Novel pesticidal proteins and strains

0001The present invention is drawn to methods and compositions for controlling plant and non-plant pests. Particularly, new pesticidal proteins are disclosed which are isolatable from the vegetative growth stage of <i>Bacillus. Bacillus</i> strains, proteins, and genes encoding the proteins are provided. The methods and compositions of the invention may be used in a variety of systems for controlling plant and non-plant pests.

0002Insect pests are a major factor in the loss of the world's commercially important agricultural crops. Broad spectrum chemical pesticides have been used extensively to control or eradicate pests of agricultural importance. There is, however, substantial interest in developing effective alternative pesticides.

0003Microbial pesticides have played an important role as alternatives to chemical pest control. The most extensively used microbial product is based on the bacterium <i>Bacillus thuringiensis</i> (Bt). Bt is a gram-positive spore forming <i>Bacillus</i> which produces an insecticidal crystal protein (ICP) during sporulation.

0004Numerous varieties of Bt are known that produce more than 25 different but related ICP's. The majority of ICP's made by Bt are toxic to larvae of certain insects in the orders <i>Lepidoptera, Diptera</i> and <i>Coleoptera.</i> In general, when an ICP is ingested by a susceptible insect the crystal is solubilized and transformed into a toxic moiety by the insect gut proteases. None of the ICP's active against coleopteran larvae such as Colorado potato beetle (<i>Leptinotarsa decemlineata</i>) or Yellow mealworm (<i>Tenebrio molitor)</i> have demonstrated significant effects on members of the genus <i>Diabrotica</i> particularly <i>Diabrotica virgifera virgifera</i>, the western corn rootworm (WCRW) or <i>Diabrotica longicornis barberi</i>, the northern corn rootworm.

0005<i>Bacillus cereus</i> (Bc) is closely related to Bt. A major distinguishing characteristic is the absence of a parasporal crystal in Bc. Bc is a widely distributed bacterium that is commonly found in soil and has been isolated from a variety of foods and drugs. The organism has been implicated in the spoilage of food.

0006Although Bt has been very useful in controlling insect pests, there is a need to expand the number of potential biological control agents.

0007Within the present invention compositions and methods for controlling plant pests are provided. In particular, novel pesticidal proteins are provided which are produced during vegetative growth of Bacillus strains. The proteins are useful as pesticidal agents.

0062Now that it has been recognized that pesticidal proteins can be isolated from the vegetative growth phase of <i>Bacillus,</i> other strains can be isolated by standard techniques and tested for activity against particular plant and non-plant pests. Generally <i>Bacillus</i> strains can be isolated from any environmental sample, including soil, plant, insect, grain elevator dust, and other sample material, etc., by methods known in the art. See, for example, Travers <i>et al</i>. (1987) <nplcit id="ncit0001" npl-type="s"><text>Appl. Environ. Microbiol. 53:1263-1266</text></nplcit>; Saleh <i>et al</i>.

0064In accordance with the present invention, the pesticidal proteins produced during vegetative growth can be isolated from <i>Bacillus.</i> In one embodiment, insecticidal proteins produced during vegetative growth, can be isolated. Methods for protein isolation are known in the art. Generally, proteins can be purified by conventional chromatography, including gel-filtration, ion-exchange, and immunoaffinity chromatography, by high-performance liquid chromatography, such as reversed-phase high-performance liquid chromatography, ion-exchange high-performance liquid chromatography, size-exclusion high-performance liquid chromatography, high-performance chromatofocusing and hydrophobic interaction chromatography, etc., by electrophoretic separation, such as one-dimensional gel electrophoresis, two-dimensional gel electrophoresis, etc. Such methods are known in the art. See for example <u>Current Protocols in Molecular Biology</u>, Vols. 1 and 2, Ausubel <i>et al</i>. (eds.), John Wiley &amp; Sons, NY (1988). Additionally, antibodies can be prepared against substantially pure preparations of the protein. See, for example, Radka <i>et al</i>. (1983) <u>J.</u><u>Immunol.</u> 128:2804; and Radka <i>et al.</i> (1984) <u>Immunogenetios</u> 19:63. Any combination of methods may be utilized to purify protein having pesticidal properties. As the protocol is being formulated, pesticidal activity is determined after each purification step.

0065Such purification steps will result in a substantially purified protein fraction. By "substantially purified" or "substantially pure" is intended protein which is substantially free of any compound normally associated with the protein in its natural state. "Substantially pure" preparations of protein can be assessed by the absence of other detectable protein bands following SDS-PAGE as determined visually or by densitometry scanning. Alternatively, the absence of other amino-terminal sequences or N-terminal residues in a purified preparation can indicate the level of purity. Purity can be verified by rechromatography of "pure" preparations showing the absence of other peaks by ion exchange, reverse phase or capillary electrophoresis. The terms "substantially pure" or "substantially purified" are not meant to exclude artificial or synthetic mixtures of the proteins with other compounds. The terms are also not meant to exclude the presence of minor impurities which do not interfere with the biological activity of the protein, and which may be present, for example, due to incomplete purification.

0066Once purified protein is isolated, the protein, or the polypeptides of which it is comprised, can be characterized and sequenced by standard methods known in the art. For example, the purified protein, or the polypeptides of which it is comprised, may be fragmented as with cyanogen bromide, or with proteases such as papain, chymotrypsin, trypsin, lysyl-C endopeptidase, etc. (Oike <i>et al</i>. (1982) <u>J.</u><u>Biol.</u><u>Chem.</u> 257:9751-9758; Liu <i>et al</i>. (1983) <u>Int.</u><u>J.</u><u>Pept.</u><u>Protein Res.</u> 21:209-215). The resulting peptides are separated, preferably by HPLC, or by resolution of gels and electroblotting onto PVDF membranes, and subjected to amino acid sequencing. To accomplish this task, the peptides are preferably analyzed by automated sequenators. It is recognized that N-terminal, C-terminal, or internal amino acid sequences can be determined. From the amino acid sequence of the purified protein, a nucleotide sequence can be synthesized which can be used as a probe to aid in the isolation of the gene encoding the pesticidal protein.

0067It is recognized that the pesticidal proteins may be oligomeric and will vary in molecular weight, number of protomers, component peptides, activity against particular pests, and in other characteristics. However, by the methods set forth herein, proteins active against a variety of pests may be isolated and characterized.

0068Once the purified protein has been isolated and characterized it is recognized that it may be altered in various ways including amino acid substitutions, deletions, truncations, and insertions. Methods for such manipulations are generally known in the art. For example, amino acid sequence variants of the pesticidal proteins can be prepared by mutations in the DNA. Such variants will possess the desired pesticidal activity. Obviously, the mutations that will be made in the DNA encoding the variant must not place the sequence out of reading frame and preferably will not create complementary regions that could produce secondary mRNA structure. See, EP Patent Application Publication No. 75,444.

0069In this manner, the present invention encompasses the pesticidal proteins as well as components and fragments thereof. That is, it is recognized that component protomers, polypeptides or fragments of the proteins may be produced which retain pesticidal activity. These fragments include truncated sequences, as well as N-terminal, C-terminal, internal and internally deleted amino acid sequences of the proteins.

0070Most deletions, insertions, and substitutions of the protein sequence are not expected to produce radical changes in the characteristics of the pesticidal protein. However, when it is difficult to predict the exact effect of the substitution, deletion, or insertion in advance of doing so, one skilled in the art will appreciate that the effect will be evaluated by routine screening assays.

0071The proteins or other component polypeptides described herein may be used alone or in combination. That is, several proteins may be used to control different insect pests.

0072Some proteins are single polypeptide chains while many proteins consist of more than one polypeptide chain, i.e., they are oligomeric. Additionally, some VIPs are pesticidally active as oligomers. In these instances, additional protomers are utilized to enhance the pesticidal activity or to activate pesticidal proteins. Those protomers which enhance or activate are referred to as auxiliary proteins. Auxiliary proteins activate or enhance a pesticidal protein by interacting with the pesticidal protein to form an oligomeric protein having increased pesticidal activity compared to that observed in the absence of the auxiliary protein.

0073Amongst the pesticidal proteins of the invention a new class of insect-specific proteins could be surprisingly identified within the scope of the present invention. The said proteins, which are designated throughout this application as VIP3, can be obtained from <i>Bacillus spp</i> strains, but preferably from <i>Bacillus thuringiensis</i> strains and most preferably from <i>Bacillus thuringiensis</i> strains AB88 and AB424. The said VIPs are present mostly in the supernatants of <i>Bacillus</i> cultures amounting to at least 75% of the total in strain AB88. The VIP3 proteins are further characterized by their unique spectrum of insectical acitivity, which includes an activity against <i>Agrotis</i> and/or <i>Spodoptera</i> species, but especially a black cutworm [BCW] and/or fall armyworm and/or beet armyworm and/or tobacco budworm and/or corn earworm activity.

0074Black cutworm is an agronomically important insect quite resistant to δ-endotoxins. Maclntosh et al (1990) J Invertebr Pathol 56, 258-266 report that the δ-endotoxins CrylA(b) and CrylA(c) possesses insecticidal properties against BCW with LC₅₀ of more than 80 µg and 18 µg/ml of diet respectively. The vip3A insecticidal proteins according to the invenition provide >50% mortality when added in an amount of protein at least 10 to 500, preferably 50 to 350, and more preferably 200 to 300 fold lower than the amount of CrylA proteins needed to achieve just 50% mortality. Especially preferred within the invention are vip3A insecticidal proteins which provide 100% mortality when added in an amount of protein at least 260 fold lower than the amount of CrylA proteins needed to achieve just 50% mortality.

0075The vip3 insecticidal proteins according to the invention are present mostly in the supernatants of the cultures and are therefore are to be classified as secreted proteins. They preferably contain in the N-terminal sequence a number of positively charged residues followed by a hydrophobic core region and are not N-terminally processed during export.

0076As the other pesticidal proteins reported hereto within the scope of the invention, the VIP3 proteins can be detected in growth stages prior to sporulation establishing a further clear distinction from other proteins that belong to the δ-endotoxin family. Preferably, expression of the insect-specific protein starts during mid-log phase and continues during sporulation. Owing to the specific expression pattern in combination with the high stability of the VIP3 proteins, large amounts of the VIP3 proteins can be found in supernatants of sporulating cultures. Especially preferred are the VIP3 proteins identified in SEQ ID NO:2 and SEQ ID NO:5 and the corresponding DNA molecules comprising nucleotide sequences encoding the said proteins, but especially those DNA molecules comprising the nucleotide sequences given in SEQ ID NO:1, SEQ ID NO:3 and SEQ ID NO:4.

0077The pesticidal proteins of the invention can be used in combination with Bt endotoxins or other insecticidal proteins to increase insect target range. Furthermore, the use of the VIPs of the present invention in combination with Bt δ-endotoxins or other insecticidal principles of a distinct nature has particular utility for the prevention and/or management of insect resistance. Other insecticidal principles include protease inhibitors (both serine and cysteine types), lectins, α-amylase and peroxidase. In one preferred embodiment, expression of VIPs in a transgenic plant is accompanied by the expression of one or more Bt δ-endotoxins. This co-expression of more than one insecticidal principle in the same transgenic plant can be achieved by genetically engineering a plant to contain and express all the genes necessary. Alternatively, a plant, Parent 1, can be genetically engineered for the expression of VIPs. A second plant, Parent 2, can be genetically engineered for the expression of Bt δ-endotoxin. By crossing Parent 1 with Parent 2, progeny plants are obtained which express all the genes introduced into Parents 1 and 2. Particularly preferred Bt δ-endotoxins are those disclosed in <patcit id="pcit0001" dnum="EP0618976A"><text>EP-A 0618976</text></patcit>, herein incorporated by reference.

0078A substantial number of cytotoxic proteins, though not all, are binary in action. Binary toxins typically consist of two protein domains, one called the A domain and the other called the B domain (see <u>Sourcebook of Bacterial Protein Toxins</u>, J. E. Alouf and J. H. Freer eds.(1991) Academic Press). The A domain possesses a potent cytotoxic activity. The B domain binds an external cell surface receptor before being internalized. Typically, the cytotoxic A domain must be escorted to the cytoplasm by a translocation domain. Often the A and B domains are separate polypeptides or protomers, which are associated by a protein-protein interaction or a di-sulfide bond. However, the toxin can be a single polypeptide which is proteolytically processed within the cell into two domains as in the case for <i>Pseudomonas</i> exotoxin A. In summary binary toxins typically have three important domains, a cytotoxic A domain, a receptor binding B domain and a translocation domain. The A and B domain are often associated by protein-protein interacting domains.

0079The receptor binding domains of the present invention are useful for delivering any protein, toxin, enzyme, transcription factor, nucleic acid, chemical or any other factor into target insects having a receptor recognized by the receptor binding domain of the binary toxins described in this patent. Similarly, since binary toxins have translocation domains which penetrate phosopholipid bilayer membranes and escort cytotoxins across those membranes, such translocation domains may be useful in escorting any protein, toxin, enzyme, transcription factor, nucleic acid, chemical or any other factor across a phospholipid bilayer such as the plasma membrane or a vesicle membrane. The translocation domain may itself perforate membranes, thus having toxic or insecticidal properties. Further, all binary toxins have cytotoxic domains; such a cytotoxic domain may be useful as a lethal protein, either alone or when delivered into any target cell(s) by any means.

0080Finally, since binary toxins comprised of two polypeptides often form a complex, it is likely that there are protein-protein interacting regions within the components of the binary toxins of the invention. These protein-protein interacting domains may be useful in forming associations between any combination of toxins, enzymes, transcription factors, nucleic acids, antibodies, cell binding moieties, or any other chemicals, factors, proteins or protein domains.

0081Toxins, enzymes, transcription factors, antibodies, cell binding moieties or other protein domains can be fused to pesticidal or auxiliary proteins by producing in frame genetic fusions which, when translated by ribosomes, would produce a fusion protein with the combined attributes of the VIP and the other component used in the fusion. Furthermore, if the protein domain fused to the VIP has an affinity for another protein, nucleic acid, carbohydrate, lipid, or other chemical or factor, then a three-component complex can be formed. This complex will have the attributes of all of its components. A similar rationale can be used for producing four or more component complexes. These complexes are useful as insecticidal toxins, pharmaceuticals, laboratory reagents, and diagnostic reagents, etc. Examples where such complexes are currently used are fusion toxins for potential cancer therapies, reagents in ELISA assays and immunoblot analysis.

0082One strategy of altering pesticidal or auxiliary proteins is to fuse a 15-amino-acid "S-tag" to the protein without destroying the insect cell binding domain(s), translocation domains or protein-protein interacting domains of the proteins. The S-tag has a high affinity (K_d = 10^-9 M) for a ribonuclease S-protein, which, when bound to the S-tag, forms an active ribonuclease (See F. M. Richards and H. W. Wyckoff (1971) in "The Enzymes", Vol. IV (Boyer, P.D. ed.). pp. 647-806. Academic Press, New York). The fusion can be made in such a way as to destroy or remove the cytotoxic activity of the pesticidal or auxiliary protein, thereby replacing the VIP cytotoxic activity with a new cytotoxic ribonuclease activity. The final toxin would be comprised of the S-protein, a pesticidal protein and an auxiliary protein, where either the pesticidal protein or the auxiliary protein is produced as translational fusions with the S-tag. Similar strategies can be used to fuse other potential cytotoxins to pesticidal or auxiliary proteins including (but not limited to) ribosome inactivating proteins, insect hormones, hormone receptors, transcription factors, proteases, phosphatases, <i>Pseudomonas</i> exotoxin A, or any other protein or chemical factor that is lethal when delivered into cells. Similarly, proteins can be delivered into cells which are not lethal, but might after cellular biochemistry or physiology.

0083The spectrum of toxicity toward different species can be altered by fusing domains to pesticidal or auxiliary proteins which recognize cell surface receptors from other species. Such domains might include (but are not limited to) antibodies, transferrin, hormones, or peptide sequences isolated from phage displayed affinity selectable libraries. Also, peptide sequences which are bound to nutrients, vitamins, hormones, or other chemicals that are transported into cells could be used to alter the spectrum of toxicity.

0084The pesticidal proteins of the present invention are those proteins which confer a specific pesticidal property. Such proteins may vary in molecular weight, having component polypeptides at least a molecular weight of 30 kDa or greater, preferably about 50 kDa or greater.

0085It is possible that the pesticidal protein may be a component of a multimeric, pesticidal protein. Such a pesticidal protein may vary in molecular weight, having at least a molecular weight of 50 kDa up to at least 200 kDa, preferably about 100 kDa to 150 kDa.

0086For purposes of the invention, the term "Vegetative Insecticidal Protein" (VIP) encompasses those proteins produced during vegetative growth which alone or in combination can be used for pesticidal activity. This includes pesticidal proteins, auxiliary proteins and those proteins which demonstrate activity only in the presence of the auxiliary protein or the polypeptide components of these proteins.

0087It is recognized that there are alternative methods available to obtain the nucleotide and amino acid sequences of the present proteins. For example, to obtain the nucleotide sequence encoding the pesticidal protein, cosmid clones, which express the pesticidal protein, can be isolated from a genomic library. From larger active cosmid clones, smaller subclones can be made and tested for activity. In this manner, clones which express an active pesticidal protein can be sequenced to determine the nucleotide sequence of the gene. Then, an amino acid sequence can be deduced for the protein. For general molecular methods, see, for example, Molecular Cloning, A Laboratory Manual, Second Edition, Vols. 1-3, Sambrook <i>et al</i>. (eds.) Cold Spring Harbor Laboratory Press, Cold Spring Harbor, NY (1989), and the references cited therein.

0088The present invention also encompasses nucleotide sequences from organisms other than <i>Bacillus,</i> where the nucleotide sequences are isolatable by hybridization with the <i>Bacillus</i> nucleotide sequences of the invention. Proteins encoded by such nucleotide sequences can be tested for pesticidal activity. The invention also encompasses the proteins encoded by the nucleotide sequences. Furthermore, the invention encompasses proteins obtained from organisms other than <i>Bacillus</i> wherein the protein cross-reacts with antibodies raised against the proteins of the invention. Again the isolated proteins can be assayed for pesticidal activity by the methods disclosed herein or others well-known in the art.

0089Once the nucleotide sequences encoding the pesticidal proteins of the invention have been isolated, they can be manipulated and used to express the protein in a variety of hosts including other organisms, including microorganisms and plants.

0090The pesticidal genes of the invention can be optimized for enhanced expression in plants. See, for example <patcit id="pcit0002" dnum="EP0618976A"><text>EP-A 0618976</text></patcit>; <patcit id="pcit0003" dnum="EP0359472A"><text>EP-A 0359472</text></patcit>; <patcit id="pcit0004" dnum="EP0385962A"><text>EP-A 0385962</text></patcit>; <patcit id="pcit0005" dnum="WO9116432A"><text>WO 91/16432</text></patcit>; <nplcit id="ncit0004" npl-type="s"><text>Perlak et al.

In this manner, the genes can be synthesized utilizing plant preferred codons. That is the preferred codon for a particular host is the single codon which most frequently encodes that amino acid in that host. The maize preferred codon, for example, for a particular amino acid may be derived from known gene sequences from maize. Maize codon usage for 28 genes from maize plants is found in <nplcit id="ncit0006" npl-type="s"><text>Murray et al. (1989), Nucleic Acids Research 17:477-498</text></nplcit>, the disclosure of which is incorporated herein by reference. Synthetic genes can also be made based on the distribution of codons a particular host uses for a particular amino acid.

0091In this manner, the nucleotide sequences can be optimized for expression in any plant. It is recognized that all or any part of the gene sequence may be optimized or synthetic. That is, synthetic or partially optimized sequences may also be used.

0092In like manner, the nucleotide sequences can be optimized for expression in any microorganism. For <i>Bacillus</i> preferred codon usage, see, for example <patcit id="pcit0006" dnum="US5024837A"><text>US Patent No. 5,024,837</text></patcit> and <nplcit id="ncit0007" npl-type="s"><text>Johansen et al. (1988) Gene 65:293-304</text></nplcit>.

0093Methodologies for the construction of plant expression cassettes as well as the introduction of foreign DNA into plants are described in the art. Such expression cassettes may include promoters, terminators, enhancers, leader sequences, introns and other regulatory sequences operably linked to the pesticidal protein coding sequence. It is further recognized that promoters or terminators of the VIP genes can be used in expression cassettes.

0094Generally, for the introduction of foreign DNA into plants Ti plasmid vectors have been utilized for the delivery of foreign DNA as well as direct DNA uptake, liposomes, electroporation, micro-injection, and the use of microprojectiles. Such methods had been published in the art.

It is understood that the method of transformation will depend upon the plant cell to be transformed.

0095It is further recognized that the components of the expression cassette may be modified to increase expression. For example, truncated sequences, nucleotide substitutions or other modifications may be employed. See, for example <nplcit id="ncit0014" npl-type="s"><text>Perlak et al. (1991) Proc. Natl. Acad.

0098For tissue specific expression, the nucleotide sequences of the invention can be operably linked to tissue specific promoters. See, for example, <patcit id="pcit0011" dnum="EP0618976A"><text>EP-A 0618976</text></patcit>, herein incorporated by reference.

0099Further comprised within the scope of the present invention are transgenic plants, in particular transgenic fertile plants transformed by means of the aforedescribed processes and their asexual and/or sexual progeny, which comprise and preferably also express the pesticidal protein according to the invention. Especially preferred are hybrid plants.

0100The transgenic plant according to the invention may be a dicotyledonous or a monocotyledonous plant. Preferred are monocotyledonous plants of the <i>Graminaceae</i> family involving <i><u>Lolium,</u><u>Zea</u></i>, <i><u>Triticum,</u><u>Triticale</u>, <u>Sorghum,</u><u>Saccharum,</u><u>Bromus, Oryzae,</u><u>Avena,</u><u>Hordeum,</u><u>Secale</u></i> and <i><u>Setaria</u></i> plants.

0101Especially preferred are transgenic maize, wheat, barley, sorghum, rye, oats, turf grasses and rice.

0102Among the dicotyledonous plants soybean, cotton, tobacco, sugar beet, oilseed rape, and sunflower are especially preferred herein.

0103The expression 'progeny' is understood to embrace both, "asexually" and "sexually" generated progeny of transgenic plants. This definition is also meant to include all mutants and variants obtainable by means of known processes, such as for example cell fusion or mutant selection and which still exhibit the characteristic properties of the initially transformed parent plant, together with all crossing and fusion products of the transformed plant material.

0104Another object of the invention concerns the proliferation material of transgenic plants.

0105The proliferation material of transgenic plants is defined relative to the invention as any plant material that may be propagated sexually or asexually <i>in vivo</i> or <i>in vitro.</i> Particularly preferred within the scope of the present invention are protoplasts, cells, calli, tissues, organs, seeds, embryos, pollen, egg cells, zygotes, together with any other propagating material obtained from transgenic plants.

0106Parts of plants, such as for example flowers, stems, fruits, leaves, roots originating in transgenic plants or their progeny previously transformed by means of the process of the invention and therefore consisting at least in part of transgenic cells, are also an object of the present invention.

0107Before the plant propagation material [fruit, tuber, grains, seed], but expecially seed is sold as a commerical product, it is customarily treated with a protectant coating comprising herbicides, insecticides, fungicides, bactericides, nematicides, molluscicides or mixtures of several of these preparations, if desired together with further carriers, surfactants or application-promoting adjuvants customarily employed in the art of formulation to provide protection against damage caused by bacterial, fungal or animal pests.

0108In order to treat the seed, the protectant coating may be applied to the seeds either by impregnating the tubers or grains with a liquid formulation or by coating them with a combined wet or dry formulation. In addition, in special cases, other methods of application to plants are possible, eg treatment directed at the buds or the fruit.

0109The plant seed according to the invention comprising a DNA molecule comprising a nucleotide sequence encoding a pesticidal protein according to the invention may be treated with a seed protectant coating comprising a seed treatment compound, such as, for example, captan, carboxin, thiram (TMTD®), methalaxyl (Apron®) and pirimiphos-methyl (Actellic®) and others that are commonly used in seed treatment. Preferred within the scope of the invention are seed protectant coatings comprising an entomocidal composition according to the invention alone or in combination with one of the a seed protectant coating customarily used in seed treatment.

0110It is thus a further object of the present invention to provide plant propagation material for cultivated plants, but especially plant seed that is treated with a seed protectant coating as defined hereinbefore.

0111It is recognized that the genes encoding the pesticidal proteins can be used to transform insect pathogenic organisms. Such organisms include Baculoviruses, fungi, protozoa, bacteria and nematodes.

0112The <i>Bacillus</i> strains of the invention may be used for protecting agricultural crops and products from pests. Alternatively, a gene encoding the pesticide may be introduced via a suitable vector into a microbial host, and said host applied to the environment or plants or animals. Microorganism hosts may be selected which are known to occupy the "phytosphere" (phylloplane, phyllosphere, rhizosphere, and/or rhizoplana) of one or more crops of interest. These microorganisms are selected so as to be capable of successfully competing in the particular environment with the wild-type microorganisms, provide for stable maintenance and expression of the gene expressing the polypeptide pesticide, and, desirably, provide for improved protection of the pesticide from environmental degradation and inactivation.

0113Such microorganisms include bacteria, algae, and fungi. Of particular interest are microorganisms, such as bacteria, e.g., <i>Pseudomonas, Erwinia, Serratia, Klebsiella</i>, <i>Xanthomonas, Streptomyces, Rhizobium, Rhodopseudomonas, Methylius, Agrobacterium, Acetobacter, Lactobacillus, Arthrobacter, Azotobacter, Leuconostoc,</i> and <i>Alcaligenes;</i> fungi, particularly yeast, e.g., <i>Saccharomyces, Cryptococcus</i>, <i>Kluyveromyces, Sporobolomyces, Rhodotorula,</i> and <i>Aureobasidium.</i> Of particular interest are such phytosphere bacterial species as <i>Pseudomonas syringae</i>, <i>Pseudomonas fluorescens, Serratia marcescens, Acetobacter xylinum, Agrobacteria, Rhodopseudomonas spheroides, Xanthomonas campestris, Rhizobium melioti, Alcaligenes entrophus, Clavibacter xyli and Azotobacter vinlandir,</i> and phytosphere yeast species such as <i>Rhodotorula rubra, R. glutinis, R. marina, R. aurantiaca</i>, <i>Cryptococcus albidus, C. diffluens, C. laurentii, Saccharomyces rosei, S. pretoriensis, S. cerevisiae, Sporobolomyces rosues, S. odorus, Kluyveromyces veronae</i>, and <i>Aureobasidium pollulans</i>. Of particular interest are the pigmented microorganisms.

0114A number of ways are available for introducing a gene expressing the pesticidal protein into the microorganism host under conditions which allow for stable maintenance and expression of the gene. For example, expression cassettes can be constructed which include the DNA constructs of interest operably linked with the transcriptional and translational regulatory signals for expression of the DNA constructs, and a DNA sequence homologous with a sequence in the host organism, whereby integration will occur, and/or a replication system which is functional in the host, whereby integration or stable maintenance will occur.

0115Transcriptional and translational regulatory signals include but are not limited to promoter, transcriptional initiation start site, operators, activators, enhancers, other regulatory elements, ribosomal binding sites, an initiation codon, termination signals, and the like. See, for example, <patcit id="pcit0012" dnum="US5039523A"><text>US Patent 5,039,523</text></patcit>; <patcit id="pcit0013" dnum="US4853331A"><text>US Patent No. 4,853,331</text></patcit>; <patcit id="pcit0014" dnum="EP0480762A2"><text>EPO 0480762A2</text></patcit>; Sambrook <i>et al</i>. <u>supra</u>; Molecular Cloning, a Laboratory Manual, Maniatis <i>et al.</i> (eds) Cold Spring Harbor Laboratory, Cold Spring Harbor, NY (1982); Advanced Bacterial Genetics, Davis <i>et al</i>. (eds.) Cold Spring Harbor Laboratory, Cold Spring Harbor, NY (1980); and the references cited therein.

0116Suitable host cells, where the pesticide-containing cells will be treated to prolong the activity of the toxin in the cell when the then treated cell is applied to the environment of the target pest(s), may include either prokaryotes or eukaryotes, normally being limited to those cells which do not produce substances toxic to higher organisms, such as mammals. However, organisms which produce substances toxic to higher organisms could be used, where the toxin is unstable or the level of application sufficiently low as to avoid any possibility of toxicity to a mammalian host. As hosts, of particular interest will be the prokaryotes and the lower eukaryotes, such as fungi. Illustrative prokaryotes, both Gram-negative and -positive, include <i>Enterobacteriaceae,</i> such as <i>Escherichia, Erwinia, Shigella, Salmonella,</i> and <i>Proteus</i>; <i>Bacillaceae; Rhizobiceae, such as Rhizobium; Spirillaceae,</i> such as photobacterium, <i>Zymomonas, Serratia, Aeromonas, Vibrio, Desulfovibrio, Spirillum; Lactobacillaceae; Pseudomonadaceae,</i> such as <i>Pseudomonas</i> and <i>Acetobacter; Azotobacteraceae</i> and <i>Nitrobacteraceae.</i> Among eukaryotes are fungi, such as <i>Phycomycetes</i> and <i>Ascomycetes,</i> which includes yeast, such a <i>Saccharomyces</i> and <i>Schizosaccharromyces;</i> and <i>Basidiomycetes</i> yeast, such as <i>Rhodotorula, Aureobasidium, Sporobolomyces,</i> and the like.

0117Characteristics of particular interest in selecting a host cell for purposes of production include ease of introducing the protein gene into the host, availability of expression systems, efficiency of expression, stability of the protein in the host, and the presence of auxiliary genetic capabilities. Characteristics of interest for use as a pesticide microcapsule include protective qualities for the pesticide, such as thick cell walls, pigmentation, and intracellular packaging or formation of inclusion bodies; leaf affinity; lack of mammalian toxicity; attractiveness to pests for ingestion; ease of killing and fixing without damage to the toxin; and the like. Other considerations include ease of formulation and handling, economics, storage stability, and the like.

0118Host organisms of particular interest include yeast, such as <i>Rhodotorula sp., Aureobasidium sp., Saccharomyces sp., and Sporobolomyces sp</i>.; phylloplane organisms such as <i>Pseudomonas sp., Erwinia sp</i>. and <i>Flavobacterium sp</i>.; or such other organisms as <i>Escherichia, LactoBacillus sp., Bacillus sp.,</i> and the like. Specific organisms include <i>Pseudomonas aeurginosa, Pseudomonas fluorescens, Saccharomyces cerevisiae, Bacillus thuringiensis, Escherichia coli, Bacillus subtilis,</i> and the like.

0119VIP genes can be introduced into micro-organisms that multiply on plants (epiphytes) to deliver VIP proteins to potential target pests. Epiphytes can be gram-positive or gram-negative bacteria for example.

0120Root colonizing bacteria, for example, can be isolated from the plant of interest by methods known in the art. Specifically, a <i>Bacillus cereus</i> strain which colonizes roots could be isolated from roots of a plant ( for example see <nplcit id="ncit0039" npl-type="s"><text>J. Handelsman, S. Raffel, E. Mester, L. Wunderlich and C. Grau, Appl. Environ. Microbiol. 56:713-718, (1990)</text></nplcit>). VIP1 and/or VIP2 and/or VIP3 could be introduced into a root colonizing <i>Bacillus</i> cereus by standard methods known in the art.

0121Also, VIP3 or other VIPs of the invention can be introduced into the root colonizing <i>Bacillus</i> by means of electro-transformation. Specifically, VIPs can be cloned into a shuttle vector, for example, pHT3101 (<nplcit id="ncit0040" npl-type="s"><text>D. Lereclus et al., FEMS Microbiol. Letts., 60:211-218 (1989)</text></nplcit>) as described in Example 10. The shuttle vector pHT3101 containing the coding sequence for the particular VIP can then be transformed into the root colonizing <i>Bacillus</i> by means of electroporation (<nplcit id="ncit0041" npl-type="s"><text>D. Lereclus et al. 1989, FEMS Microbiol. Letts. 60:211-218</text></nplcit>).

0122Expression systems can be designed so that VIP proteins are secreted outside the cytoplasm of gram negative bacteria, <i>E. coli</i>, for example. Advantages of having VIP proteins secreted are (1) it avoids potential toxic effects of VIP proteins expressed within the cytoplasm and (2) it can increase the level of VIP protein expressed and (3) can aid in efficient purification of VIP protein.

0123VIP proteins can be made to be secreted in <i>E. coli</i>, for example, by fusing an appropriate <i>E. coli</i> signal peptide to the amino-terminal end of the VIP signal peptide or replacing the VIP signal peptide with the <i>E. coli</i> signal peptide. Signal peptides recognized by <i>E. coli</i> can be found in proteins already known to be secreted in <i>E. coli</i>, for example the OmpA protein (<nplcit id="ncit0042" npl-type="s"><text>J. Ghrayeb, H. Kimura, M. Takahara, Y. Masui and M. Inouye, EMBO J., 3:2437-2442 (1984)</text></nplcit>). OmpA is a major protein of the <i>E. coli</i> outer membrane and thus its signal peptide is thought to be efficient in the translocation process. Also, the OmpA signal peptide does not need to be modified before processing as may be the case for other signal peptides, for example lipoprotein signal peptide ( <nplcit id="ncit0043" npl-type="s"><text>G. Duffaud, P. March and M. Inouye, Methods in Enzymology, 153:492 (1987</text></nplcit>)).

0124Specifically, unique BamHI restriction sites can be introduced at the amino-terminal and carboxy-terminal ends of the VIP coding sequences using standard methods known in the art. These BamHI fragments can be cloned, in frame, into the vector pIN-III-ompA1, A2 or A3 (<nplcit id="ncit0044" npl-type="s"><text>J. Ghrayeb, H. Kimura, M. Takahara, H. Hsiung, Y. Masui and M. Inouye, EMBO J., 3:2437-2442 (1984)</text></nplcit>) thereby creating ompA:VIP fusion gene which is secreted into the periplasmic space. The other restriction sites in the polylinker of pIN-III-ompA can be eliminated by standard methods known in the art so that the VIP amino-terminal amino acid coding sequence is directly after the ompA signal peptide cleavage site. Thus, the secreted VIP sequence in <i>E. coli</i> would then be identical to the native VIP sequence.

0125When the VIP native signal peptide is not needed for proper folding of the mature protein, such signal sequences can be removed and replaced with the ompA signal sequence. Unique BamHI restriction sites can be introduced at the amino-termini of the proprotein coding sequences directly after the signal peptide coding sequences of VIP and at the carboxy-termini of VIP coding sequence. These BamHI fragments can then be cloned into the pIN-III-ompA vectors as described above.

0126General methods for employing the strains of the invention in pesticide control or in engineering other organisms as pesticidal agents are known in the art. See, for example <patcit id="pcit0015" dnum="US5039523A"><text>US Patent No. 5,039,523</text></patcit> and <patcit id="pcit0016" dnum="EP0480762A2A"><text>EP 0480762A2</text></patcit>.

0127VIPs can be fermented in a bacterial host and the resulting bacteria processed and used as a microbial spray in the same manner that <i>Bacillus thuringiensis</i> strains have been used as insecticidal sprays. In the case of a VIP(s) which is secreted from <i>Bacillus,</i> the secretion signal is removed or mutated using procedures known in the art. Such mutations and/or deletions prevent secretion of the VIP protein(s) into the growth medium during the fermentation process. The VIPs are retained within the cell and the cells are then processed to yield the encapsulated VIPs. Any suitable microorganism can be used for this purpose. <i>Psuedomonas</i> has been used to express <i>Bacillus thuringiensis</i> endotoxins as encapsulated proteins and the resulting cells processed and sprayed as an insecticide. (H. Gaertner <i>et al</i>. 1993, In Advanced Engineered Pesticides, L. Kim ed.)

0128Various strains of <i>Bacillus thuringiensis</i> are used in this manner. Such Bt strains produce endotoxin protein(s) as well as VIPs. Alternatively, such strains can produce only VIPs. A sporulation deficient strain of <i>Bacillus subtilis</i> has been shown to produce high levels of the CryIIIA endotoxin from <i>Bacillus thuringiensis</i> (<nplcit id="ncit0045" npl-type="s"><text>Agaisse, H. and Lereclus, D., "Expression in Bacillus subtilis of the Bacillus thuringiensis CryIIIA toxin gene is not dependent on a sporulation-specific sigma factor and is increased in a spoOA mutant", J. Bacteriol., 176:4734-4741 (1994)</text></nplcit>). A similar <i>spoOA</i> mutant can be prepared in <i>Bacillus thuringiensis</i> and used to produce encapsulated VIPs which are not secreted into the medium but are retained within the cell.

0129To have VIPs maintained within the <i>Bacillus</i> cell the signal peptide can be disarmed so that it no longer functions as a secretion signal.

0130Alternatively, the signal peptides of VIPs of the invention can be eliminated from the sequence thereby making them unrecognizable as secretion proteins in <i>Bacillus</i>. Specifically, a methionine start site can be engineered in front of the proprotein sequence in using methods known in the art.

0131VIP genes can be introduced into micro-organisms that mutiply on plants (epiphytes) to deliver VIP proteins to potential target pests. Epiphytes can be gram-positive or gram-negative bacteria for example.

0132The <i>Bacillus</i> strains of the invention or the microorganisms which have been genetically altered to contain the pesticidal gene and protein may be used for protecting agricultural crops and products from pests. In one aspect of the invention, whole, i.e., unlysed, cells of a toxin (pesticide)-producing organism are treated with reagents that prolong the activity of the toxin produced in the cell when the cell is applied to the environment of target pest(s).

0133Alternatively, the pesticides are produced by introducing a heterologous gene into a cellular host. Expression of the heterologous gene results, directly or indirectly, in the intracellular production and maintenance of the pesticide. These cells are then treated under conditions that prolong the activity of the toxin produced in the cell when the cell is applied to the environment of target pest(s). The resulting product retains the toxicity of the toxin. These naturally encapsulated pesticides may then be formulated in accordance with conventional techniques for application to the environment hosting a target pest, e.g., soil, water, and foliage of plants. See, for example EPA 0192319, and the references cited therein.

0134The active ingredients of the present invention are normally applied in the form of compositions and can be applied to the crop area or plant to be treated, simultaneously or in succession, with other compounds. These compounds can be both fertilizers or micronutrient donors or other preparations that influence plant growth. They can also be selective herbicides, insecticides, fungicides, bactericides, nematicides, mollusicides or mixtures of several of these preparations, if desired, together with further agriculturally acceptable carriers, surfactants or application-promoting adjuvants customarily employed in the art of formulation. Suitable carriers and adjuvants can be solid or liquid and correspond to the substances ordinarily employed in formulation technology, e.g. natural or regenerated mineral substances, solvents, dispersants, wetting agents, tackifiers, binders or fertilizers.

0135Preferred methods of applying an active ingredient of the present invention or an agrochemical composition of the present invention which contains at least one of the insect-specific proteins produced by the bacterial strains of the present invention are leaf application, seed coating and soil application. The number of applications and the rate of application depend on the intensity of infestation by the corresponding pest.

0136The present invention thus further provides an entomocidal composition comprising as an active ingrdient at least one of the novel insect-specific proteins according to the invention and/or a recombinant microorganism containing at least one DNA molecule comprising a nucleotide sequence encoding the novel insect-specific proteins in recombinant form, but especially a recombinant <i>Bacillus spp</i> strain, such as <i>Bacillus cereus</i> or <i>Bacillus thuringiensis,</i> containing at least one one DNA molecule comprising a nucleotide sequence encoding the novel insect-specific proteins in recombinant form, or a derivative or mutant thereof, together with an agricultural adjuvant such as a carrier, diluent, surfactant or application-promoting adjuvant. The composition may also contain a further biologically active compound. The said compound can be both a fertilizer or micronutrient donor or other preparations that influence plant growth. It can also be a selective herbicide, insecticide, fungicide, bactericide, nematicide, molluscide or mixtures of several of these preparations, if desired, together with further agriculturally acceptable carriers, surfactants or application-promoting adjuvants customarily employed in the art of formulation. Suitable carriers and adjuvants can be solid or liquid and correspond to the substances ordinarily employed in formulation technology, e.g. natural or regenerated mineral substances, solvents, dispersants, wetting agents, tackifiers, binders or fertilizers

0137The composition may comprise from 0.1 to 99% by weight of the active ingredient, from 1 to 99.9% by weight of a solid or liquid adjuvant, and from 0 to 25% by weight of a surfactant. The acitve ingredient comprising at least one of the novel insect-specific proteins according to the invention or a recombinant microorganism containing at least one DNA molecule comprising a nucleotide sequence encoding the novel insect-specific proteins in recombinant form, but especially a recombinant <i>Bacillus spp strain</i>, <i>such as Bacillus cereus or Bacillus thuringiensis</i> strain containing at least one DNA molecule comprising a nucleotide sequence encoding the novel insect-specific proteins in recombinant form, or a derivative or mutant thereof, or the composition containing the said acitve ingredient, may be administered to the plants or crops to be protected together with certain other insecticides or chemicals (1993 Crop Protection Chemicals Reference, Chemical and Pharmaceutical Press, Canada) without loss of potency. It is compatible with most other commonly used agricultural spray materials but should not be used in extremely alkaline spray solutions. It may be administered as a dust, a suspension, a wettable powder or in any other material form suitable for agricultural application.

0138The invention further provides methods for for controlling or inhibiting of insect pests by applying an active ingredient comprising at least one of the novel insect-specific proteins according to the invention or a recombinant microorganism containing at least one DNA molecule comprising a nucleotide sequence encoding the novel insect-specific proteins in recombinant form or a composition comprising the said active ingredient to (a) an environment in which the insect pest may occur, (b) a plant or plant part in order to protect said plant or plant part from damage caused by an insect pest, or (c) seed in order to protect a plant which develops from said seed from damage caused by an insect pest.

0139A preferred method of application in the area of plant protection is application to the foliage of the plants (foliar application), with the number of applications and the rate of application depending on the plant to be protected and the risk of infestation by the pest in question. However, the active ingredient may also penetrate the plants through the roots (systemic action) if the locus of the plants is impregnated with a liquid formulation or if the active ingredient is incorporated in solid form into the locus of the plants, for example into the soil, e.g. in granular form (soil application). In paddy rice crops, such granules may be applied in metered amounts to the flooded rice field.

0140The compositions according to the invention are also suitable for protecting plant propagating material, e.g. seed, such as fruit, tubers or grains, or plant cuttings, from insect pests. The propagation material can be treated with the formulation before planting: seed, for example, can be dressed before being sown. The acitve ingredient of the invention can also be applied to grains (coating), either by impregnating the grains with a liquid formulation or by coating them with a solid formulation. The formulation can also be applied to the planting site when the propagating material is being planted, for example to the seed furrow during sowing. The invention relates also to those methods of treating plant propagation material and to the plant propagation material thus treated.

0141The compositions according to the invention comprising as an active ingredient a recombinant microorganism containing at least one of the novel toxin genes in recombinant form, but especially a recombinant <i>Bacillus spp strain, such as Bacillus cereus or Bacillus thuringiensis</i> strain containing at least one DNA molecule comprising a nucleotide sequence encoding the novel insect-specific proteins in recombinant form, or a derivative or mutant thereof may be applied in any method known for treatment of seed or soil with bacterial strains. For example, see <patcit id="pcit0017" dnum="US4863866A"><text>US Patent No.4,863,866</text></patcit>. The strains are effective for biocontrol even if the microorganism is not living. Preferred is, however, the application of the living microorganism.

0142Target crops to be protected within the scope of the present invention comprise, e.g., the following species of plants: <ul id="ul0005" list-style="none" compact="compact"><li>cereals (wheat, barley, rye, oats, rice, sorghum and related crops), beet (sugar beet and fodder beet), forage grasses (orchardgrass, fescue, and the like), drupes, pomes and soft fruit (apples, pears, plums, peaches, almonds, cherries, strawberries, raspberries and blackberries), leguminous plants (beans, lentils, peas, soybeans), oil plants (rape, mustard, poppy, olives, sunflowers, coconuts, castor oil plants, cocoa beans, groundnuts), cucumber plants (cucumber, marrows, melons) fiber plants (cotton, flax, hemp, jute), citrus fruit (oranges, lemons, grapefruit, mandarins), vegetables (spinach, lettuce, asparagus, cabbages and other Brassicae, onions, tomatoes, potatoes, paprika), lauraceae (avocados, carrots, cinnamon, camphor), deciduous trees and conifers (e.g. linden-trees, yew-trees, oak-trees, alders, poplars, birch-trees, firs, larches, pines), or plants such as maize, tobacco, nuts, coffee, sugar cane, tea, vines, hops, bananas and natural rubber plants, as well as ornamentals (including composites).</li></ul>

0143A recombinant <i>Bacillus spp strain, such as Bacillus cereus or Bacillus thuringiensis</i> strain, containing at least one DNA molecule comprising a nucleotide sequence encoding the novel insect-specific proteins in recombinant form is normally applied in the form of entomocidal compositions and can be applied to the crop area or plant to be treated, simultaneously or in succession, with further biologically active compounds. These compounds may be both fertilizers or micronutrient donors or other preparations that influence plant growth. They may also be selective herbicides, insecticides, fungicides, bactericides, nematicides, molluscicides or mixtures of several of these preparations, if desired together with further carriers, surfactants or application-promoting adjuvants customarily employed in the art of formulation.

0144The active ingredient according to the invention may be used in unmodified form or together with any suitable agriculturally acceptable carrier. Such carriers are adjuvants conventionally employed in the art of agricultural formulation, and are therefore formulated in known manner to emulsifiable concentrates, coatable pastes, directly sprayable or dilutable solutions, dilute emulsions, wettable powders, soluble powders, dusts, granulates, and also encapsulations, for example, in polymer substances. Like the nature of the compositions, the methods of application, such as spraying, atomizing, dusting, scattering or pouring, are chosen in accordance with the intended objective and the prevailing circumstances. Advantageous rates of application are normally from about 50 g to about 5 kg of active ingredient (a.i.) per hectare ("ha", approximately 2.471 acres), preferably from about 100 g to about 2kg a.i./ha. Important rates of application are about 200 g to about 1 kg a.i./ha and 200g to 500g a.i./ha. For seed dressing advantageous application rates are 0.5 g to 1000 g a.i.per 100 kg seed, preferably 3 g to 100 g a.i. per 100 kg seed or 10 g to 50 g a.i.per 100 kg seed.

0145Suitable carriers and adjuvants can be solid or liquid and correspond to the substances ordinarily employed in formulation technology, e.g. natural or regenerated mineral substances, solvents, dispersants, wetting agents, tackifiers, binders or fertilizers. The formulations, i.e. the entomocidal compositions, preparations or mixtures containing the recombinant <i>Bacillus spp strain, such as Bacillus cereus or Bacillus thuringiensis</i> strain containing at least one DNA molecule comprising a nucleotide sequence encoding the novel insect-specific proteins in recombinant form as an active ingredient or combinations thereof with other active ingredients, and, where appropriate, a solid or liquid adjuvant, are prepared in known manner, e.g., by homogeneously mixing and/or grinding the active ingredients with extenders, e.g., solvents, solid carriers, and in some cases surface-active compounds (surfactants).

0146Suitable solvents are: aromatic hydrocarbons, preferably the fractions containing 8 to 12 carbon atoms, e.g. xylene mixtures or substituted naphthalenes, phthalates such as dibutyl phthalate or dioctyl phthalate, aliphatic hydrocarbons such as cyclohexane or paraffins, alcohols and glycols and their ethers and esters, such as ethanol, ethylene glycol monomethyl or monoethyl ether, ketones such as cyclohexanone, strongly polar solvents such as N-methyl-2-pyrrolidone, dimethylsulfoxide or dimethylformamide, as well as vegetable oils or epoxidised vegetable oils such as epoxidised coconut oil or soybean oil; or water.

0147The solid carriers used, e.g., for dusts and dispersible powders, are normally natural mineral fillers such as calcite, talcum, kaolin, montmorillonite or attapulgite. In order to improve the physical properties it is also possible to add highly dispersed silicic acid or highly dispersed absorbent polymers. Suitable granulated adsorptive carriers are porous types, for example pumice, broken brick, sepiolite or bentonite; and suitable nonsorbent carriers are materials such as calcite or sand. In addition, a great number of pregranulated materials of inorganic or organic nature can be used, e.g. especially dolomite or pulverized plant residues.

0148Depending on the nature of the active ingredients to be formulated, suitable surface-active compounds are non-ionic, cationic and/or anionic surfactants having good emulsifying, dispersing and wetting properties. The term "surfactants" will also be understood as comprising mixtures of surfactants. Suitable anionic surfactants can be both water-soluble soaps and water-soluble synthetic surface-active compounds. Suitable soaps are the alkali metal salts, alkaline earth metal salts or unsubstituted or substituted ammonium salts of higher fatty acids (C₁₀ -C₂₂), e.g. the sodium or potassium salts of oleic or stearic acid, or of natural fatty acid mixtures which can be obtained, e.g. from coconut oil or tallow oil. Further suitable surfactants are also the fatty acid methyltaurin salts as well as modified and unmodified phospholipids.

0149More frequently, however, so-called synthetic surfactants are used, especially fatty sulfonates, fatty sulfates, sulfonated benzimidazole derivatives or alkylarylsulfonates. The fatty sulfonates or sulfates are usually in the forms of alkali metal salts, alkaline earth metal salts or unsubstituted or substituted ammonium salts and generally contain a C₈ -C₂₂ alkyl radical which also includes the alkyl moiety of acyl radicals, e.g. the sodium or calcium salt of lignosulfonic acid, of dodecylsulfate, or of a mixture of fatty alcohol sulfates obtained from natural fatty acids. These compounds also comprise the salts of sulfuric acid esters and sulfonic acids of fatty alcohol/ethylene oxide adducts. The sulfonated benzimidazole derivatives preferably contain 2 sulfonic acid groups and one fatty acid radical containing about 8 to 22 carbon atoms. Examples of alkylarylsulfonates are the sodium, calcium or triethanolamine salts of dodecylbenzenesulfonic acid, dibutylnaphthalenesulfonic acid, or of a naphthalenesulfonic acid/formaldehyde condensation product. Also suitable are corresponding phosphates, e.g. salts of the phosphoric acid ester of an adduct of p-nonylphenol with 4 to 14 moles of ethylene oxide. Non-ionic surfactant are preferably polyglycol ether derivatives of aliphatic or cycloaliphatic alcohols, or saturated or unsaturated fatty acids and alkylphenols, said derivatives containing 3 to 30 glycol ether groups and 8 to 20 carbon atoms in the (aliphatic) hydrocarbon moiety and 6 to 18 carbon atoms in the alkyl moiety of the alkylphenols.

0150Further suitable non-ionic surfactants are the water-soluble adducts of polyethylene oxide with polypropylene glycol, ethylenediaminopolypropylene glycol and alkylpolypropylene glycol containing 1 to 10 carbon atoms in the alkyl chain, which adducts contain 20 to 250 ethylene glycol ether groups and 10 to 100 propylene glycol ether groups. These compounds usually contain 1 to 5 ethylene glycol units per propylene glycol unit. Representative examples of non-ionic surfactants are nonylphenolpolyethoxyethanols, castor oil polyglycol ethers, polypropylene/polyethylene oxide adducts, tributylphenoxypolyethoxyethanol, polyethylene glycol and octylphenoxypolyethoxyethanol. Fatty acid esters of polyoxyethylene sorbitan, such as polyoxyethylene sorbitan trioleate, are also suitable non-ionic surfactants.

0151Cationic surfactants are preferably quaternary ammonium salts which contain, as N-substituent, at least one C₈ -C₂₂ alkyl radical and, as further substituents, lower unsubstituted or halogenated alkyl, benzyl or hydroxyl-lower alkyl radicals. The salts are preferably in the form of halides, methylsulfates or ethylsulfates, e.g., stearyltrimethylammonium chloride or benzyldi-(2-chloroethyl)ethylammonium bromide.

0152The surfactants customarily employed in the art of formulation are described, e.g., in "McCutcheon's Detergents and Emulsifiers Annual", MC Publishing Corp. Ridgewood, N.J., 1979; Dr. Helmut Stache, "Tensid Taschenbuch" (Handbook of Surfactants), Carl Hanser Verlag, MunichNienna.

0153Another particularly preferred characteristic of an entomocidal composition of the present invention is the persistence of the active ingredient when applied to plants and soil. Possible causes for loss of activity include inactivation by ultra-violet light, heat, leaf exudates and pH. For example, at high pH, particularly in the presence of reductant, δ-endotoxin crystals are solubilized and thus become more accessible to proteolytic inactivation. High leaf pH might also be important, particularly where the leaf surface can be in the range of pH 8-10. Formulation of an entomocidal composition of the present invention can address these problems by either including additives to help prevent loss of the active ingredient or encapsulating the material in such a way that the active ingredient is protected from inactivation. Encapsulation can be accomplished chemically (<nplcit id="ncit0046" npl-type="s"><text>McGuire and Shasha, J Econ Entomol 85: 1425-1433, 1992</text></nplcit>) or biologically (Barnes and Cummings, 1986; <patcit id="pcit0018" dnum="EP0192319A"><text>EP-A 0 192 319</text></patcit>). Chemical encapsulation involves a process in which the active ingredient is coated with a polymer while biological encapsulation involves the expression of the δ-endotoxin genes in a microbe. For biological encapsulation, the intact microbe containing at least one DNA molecule comprising a nucleotide sequence encoding the novel insect-specific proteins in recombinant form is used as the active ingredient in the formulation. The addition of UV protectants might effectively reduce irradiation damage. Inactivation due to heat could also be controlled by including an appropriate additive.

0154Preferred within the present application are formulations comprising living microorganisms as active ingredient either in form of the vegetative cell or more preferable in form of spores, if available. Suitable formulations may consist, for example, of polymer gels which are crosslinked with polyvalent cations and comprise these microorganisms. This is described, for example, by <nplcit id="ncit0047" npl-type="s"><text>D.R. Fravel et al. in Phytopathology, Vol. 75, No. 7, 774-777, 1985</text></nplcit> for alginate as the polymer material. It is also known from this publication that carrier materials can be co-used. These formulations are as a rule prepared by mixing solutions of naturally occurring or synthetic gel-forming polymers, for example alginates, and aqueous salt solutions of polyvalent metal ions such that individual droplets form, it being possible for the microorganisms to be suspended in one of the two or in both reaction solutions. Gel formation starts with the mixing in drop form. Subsequent drying of these gel particles is possible. This process is called ionotropic gelling. Depending on the degree of drying, compact and hard particles of polymers which are structurally crosslinked via polyvalent cations and comprise the microorganisms and a carrier present predominantly uniformly distributed are formed. The size of the particles can be up to 5 mm.

0155Compositions based on partly crosslinked polysaccharides which, in addition to a microorganism, for example, can also comprise finely divided silicic acid as the carrier material, crosslinking taking place, for example, via Ca⁺⁺ ions, are described in <patcit id="pcit0019" dnum="EP0097571A1"><text>EP-A1-0 097 571</text></patcit>. The compositions have a water activity of not more than 0.3. W.J. Cornick et al. describe in a review article [New Directions in Biological Control: <ul id="ul0006" list-style="none" compact="compact"><li>Alternatives for Suppressing Agricultural Pests and Diseases, pages 345-372, Alan R. Liss, Inc. (1990)] various formulation systems, granules with vermiculite as the carrier and compact alginate beads prepared by the ionotropic gelling process being mentioned. Such compositions are also disclosed by D.R.Fravel in Pesticide Formulations and Application Systems: 11 th Volume, ASTM STP 1112 American Society for Testing and Materials, Philadelphia, 1992, pages 173 to 179 and can be used to formulate the recombinant microorganisms according to the invention.</li></ul>

0156The entomocidal compositions of the invention usually contain from about 0.1 to about 99%, preferably about 0.1 to about 95%, and most preferably from about 3 to about 90% of the active ingredient, from about 1 to about 99.9%, preferably from about 1 to about 99%, and most preferably from about 5 to about 95% of a solid or liquid adjuvant, and from about 0 to about 25%, preferably about 0.1 to about 25%, and most preferably from about 0.1 to about 20% of a surfactant.

0157In a preferred embodiment of the invention the entomocidal compositions usually contain 0.1 to 99%, preferably 0.1 to 95%, of a recombinant <i>Bacillus spp strain,</i> such as <i>Bacillus cereus or Bacillus thuringiensis</i> strain containing at least one DNA molecule comprising a nucleotide sequence encoding the novel insect-specific proteins in recombinant form, or combination thereof with other active ingredients, 1 to 99.9% of a solid or liquid adjuvant, and 0 to 25%, preferably 0.1 to 20%, of a surfactant.

0158Whereas commercial products are preferably formulated as concentrates, the end user will normally employ dilute formulations of substantially lower concentration. The entomocidal compositions may also contain further ingredients, such as stabilizers, antifoams, viscosity regulators, binders, tackifiers as well as fertilizers or other active ingredients in order to obtain special effects.

0159The invention now being generally described, the same will be better understood by reference to the following detailed examples that are provided for the purpose of illustration and are not to be considered limiting of the invention unless so specified.

<u>EXAMPLE 1. BACTERIAL CULTURE</u>

0168A subculture of Bc strain AB78 was used to inoculate the following medium, known as TB broth: <tables id="tabl0019" num="0019"><table frame="all"><tgroup cols="2" rowsep="0"><colspec colnum="1" colname="col1" colwidth="23mm" /><colspec colnum="2" colname="col2" colwidth="15mm" /><tbody><row><entry>Tryptone</entry><entry align="right">12 g/l</entry></row><row><entry>Yeast Extract</entry><entry align="right">24 g/l</entry></row><row><entry>Glycerol</entry><entry align="right">4 ml/l</entry></row><row><entry>KH₂PO₄</entry><entry align="right">2.1 g/l</entry></row><row><entry>K₂HPO₄</entry><entry align="right">14.7 g/l</entry></row><row rowsep="1"><entry>pH 7.4</entry><entry /></row></tbody></tgroup></table></tables>

0169The potassium phosphate was added to the autoclaved broth after cooling. Flasks were incubated at 30°C on a rotary shaker at 250 rpm for 24 h-36 h, which represents an early to mid-log growth phase.

0170The above procedure can be readily scaled up to large fermentors by procedures well known in the art.

0171During vegetative growth, usually 24-36 h. after starting the culture, which represents an early to mid-log growth phase, AB78 bacteria were centrifuged from the culture supernatant. The culture supernatant containing the active protein was used in bioassays.

<u>EXAMPLE 2. INSECT BIOASSAYS</u>

0172<i>B. cereus</i> strain AB78 was tested against various insects as described below.

0173Western, Northern and Southern corn rootworm, <i>Diabrotica virgifera virgifera, D. longcornis barberi</i> and <i>D. undecempunctata howardi</i>, respectively: dilutions were made of AB78 culture supernatant grown 24-36 h., mixed with molten artificial diet (<nplcit id="ncit0048" npl-type="s"><text>Marrone et al. (1985) J. of Economic Entomology 78:290-293</text></nplcit>) and allowed to solidify. Solidified diet was cut and placed in dishes. Neonate larvae were placed on the diet and held at 30 C. Mortality was recorded after 6 days.

0174<i><u>E.</u><u>coli</u></i><u>clone</u><u>bioassay</u>: <i>E. coli cells</i> were grown overnight in broth containing 100 µg/ml ampicillin at 37°C. Ten ml culture was sonicated 3X for 20 sec each. 500 µl of sonicated culture was added to molten western corn rootworm diet.

0175Colorado potato beetle, Leptinotarsa decemlineata: dilutions in Triton X-100 (to give final concentration of 0.1% TX-100) were made of AB78 culture supernatant grown 24-36 h. Five cm² potato leaf pieces were dipped into these dilutions, air dried, and placed on moistened filter paper in plastic dishes. Neonate larvae were placed on the leaf pieces and held at 30°C. Mortality was recorded after 3-5 days.

0176Yellow mealworm, <i>Tenebrio molitor</i>. dilutions were made of AB78 culture supernatant grown 24-36 h., mixed with molten artificial diet (Bioserv #F9240) and allowed to solidify. Solidified diet was cut and placed in plastic dishes. Neonate larvae were placed on the diet and held at 30°C. Mortality was recorded after 6-8 days.

0177European corn borer, black cutworm, tobacco budworm, tobacco hornworm and beet armyworm; <i>Ostrinia nubilalis, Agrotis ipsilon, Heliothis virescens, Manduca sexta</i> and <i>Spodoptera exigua,</i> respectively: dilutions, in TX-100 (to give final concentration of 0.1% TX-100), were made of AB78 culture supernatant grown 24-36 hrs. 100 µl was pipetted onto the surface of 18 cm² of solidified artificial diet (Bioserv #F9240) and allowed to air dry. Neonate larvae were then placed onto the surface of the diet and held at 30°C. Mortality was recorded after 3-6 days. Northern house mosquito, <i>Culex pipiens</i>:-dilutions were made of AB78 culture supernatant grown 24-36 h. 100 µl was pipetted into 10 ml water in a 30 ml plastic cup. Third instar larvae were added to the water and held at room temperature. Mortality was recorded after 24-48 hours.

0178The newly discovered <i>B. cereus</i> strain AB78 showed a significantly different spectrum of insecticidal activity as compared to known coleopteran active δ-endotoxins from Bt. In particular, AB78 showed more selective activity against beetles than known coleopteran-active Bt strains in that it was specifically active against <i>Diabrotica</i><u>spp</u>. More specifically, it was most active against <i>D. virgifera virgifera</i> and <i>D. longicornis barberi</i> but not <i>D. undecimpunctata howardi</i>.

0179A number of <i>Bacillus</i> strains were bioassayed for activity during vegetative growth (Table 15) against western corn rootworm. The results demonstrate that AB78 is unique in that activity against western corn rootworm is not a general phenomenon. <tables id="tabl0021" num="0021"><table frame="all"><title>TABLE 15</title><tgroup cols="2" rowsep="0"><colspec colnum="1" colname="col1" colwidth="73mm" /><colspec colnum="2" colname="col2" colwidth="67mm" /><thead valign="top"><row rowsep="1"><entry namest="col1" nameend="col2" align="left"><b>Activity of culture supernatants from various <i>Bacillus spp.</i> against western corn rootworm</b></entry></row><row rowsep="1"><entry><i>Bacillus</i> strain</entry><entry>Percent WCRW mortality</entry></row></thead><tbody><row><entry><i>B. cereus</i> AB78 (Bat.1)</entry><entry align="right">100</entry></row><row><entry><i>B. cereus</i> AB78 (Bat.2)</entry><entry align="right">100</entry></row><row><entry><i>B. cereus</i> (Carolina Bio.)</entry><entry align="right">12</entry></row><row><entry>B. cereus ATCC 11950</entry><entry align="right">12</entry></row><row><entry><i>B. cereus</i> ATCC 14579</entry><entry align="right">8</entry></row><row><entry><i>B. mycoides</i> (Carolina Bio.)</entry><entry align="right">30</entry></row><row><entry><i>B. popilliae</i></entry><entry align="right">28</entry></row><row><entry><i>B. thuringiensis</i> HD135</entry><entry align="right">41</entry></row><row><entry><i>B. thuringiensis</i> HD191</entry><entry align="right">9</entry></row><row><entry><i>B. thuringiensis</i> GC91</entry><entry align="right">4</entry></row><row><entry><i>B. thuringiensis isrealensis</i></entry><entry align="right">24</entry></row><row rowsep="1"><entry>Water Control</entry><entry align="right">4</entry></row></tbody></tgroup></table></tables>

0181The LC₅₀ was calculated to be 6.2 µl of culture supernatant per ml of western corn rootworm diet.

0182The cell pellet was also bioassayed and had no activity against WCRW. Thus, the presence of activity only in the supernatant indicates that this VIP is an exotoxin.

<u>EXAMPLE 4. PURIFICATION OF VIPS FROM STRAIN AB88:</u>

0188Bacterial liquid culture was grown overnight [for 12h] at 30°C in TB media. Cells were centrifuged at 5000 x g for 20 minutes and the supernatant retained. Proteins present in the supernatant were precipitated with ammonium sulfate (70% saturation), centrifuged [at 5000 x g for 15 minutes] and the pellet retained. The pellet was resuspended in the original volume of 20 mM Tris pH 7.5 and dialyzed overnight against the same buffer at 4°C. AB88 dialysate was more turbid than comparable material from AB78. The dialysate was titrated to pH 4.5 using 20 mM sodium citrate (pH 2.5) and, after 30 min incubation at room temperature, the solution was centrifuged at 3000 x g for 10 min. The protein pellet was redissolved in 20 mM Bis-Tris-Propane pH 9.0.

0189AB88 proteins have been separated by several different methods following clarification including isoelectric focusing (Rotofor, BioRad, Hercules, CA), precipitation at pH 4.5, ion-exchange chromotography, size exclusion chromatography and ultrafiltration. Proteins were separated on a Poros HQ/N anion exchange column (PerSeptive Biosystems, Cambridge, MA) using a linear gradient from 0 to 500 mM NaCl in 20 mM Bis-Tris-Propane pH 9.0 at a flow rate of 4 ml/min. The insecticidal protein eluted at 250 mM NaCl.

0190European corn borer (ECB)-active protein remained in the pellet obtained by pH 4.5 precipitation of dialysate. When preparative IEF was done on the dialysate using pH 3-10 ampholytes, ECB insecticidal activity was found in all fractions with pH of 7 or greater. SDS-PAGE analysis of these fractions showed protein bands of MW ∼60 kDa and ∼80 kDa. The 60 kDa and 80 kDa bands were separated by anion exchange HPLC on a Poros-Q column (PerSeptive Biosystems, Cambridge, MA). N-terminal sequence was obtained from two fractions containing proteins of slightly differing MW, but both of approximately 60 kDa in size. The sequences obtained were similar to each other and to some δ-endotoxins.

0191When the ECB-active pH 4.5 pellet was further separated by anion exchange on a Poros-Q column, activity was found only in fractions containing a major band of ∼60 kDa.

0192Black cutworm-active protein also remained in the pellet when AB88 dialysate was brought down to pH 4.5. In preparative IEF using pH 3-10 ampholytes, activity was not found in the ECB-active IEF fractions; instead, it was highest in a fraction of pH 4.5-5.0. Its major components have molecular weights of ∼35 and -80 kDa.

0193The pH 4.5 pellet was separated by anion exchange HPLC to yield fractions containing only the 35 kDa material and fractions containing both 35 kDa and 80 kDa bands.

<u>EXAMPLE 5. CHARACTERIZATION OF AB88 VIP.</u>

0194Fractions containing the various lepidopteran active vegetative proteins were generated as described in Example 4. Fractions with insecticidal acitivity were separated in 8 to 16% SDS-polyacrylamide gels and transferred to PVDF membranes [LeGendre et al, (1989) in: A Practical Guide to Protein and Peptide Purification for Microsequencing, ed Matsudaria PT (Academic Press Inc, New Yorkl]. Biological analysis of fractions demonstrated that different VIPs were responsible for the different lepidopteran species activity.

0195The <i>Agrotis ipsilon</i> activity is due to an 80 kDa and/or a 35 kDa protein, either delivered singly or in combination. These proteins are not related to any δ-endotoxins from Bt as evidenced by the lack of sequence homology of known Bt δ-endotoxin sequences. The vip3A(a) insecticidal protein from strain AB88 is present mostly (at least 75% of the total) in supernatants of AB88 cultures.

0196Also, these proteins are not found in the AB88 δ-endotoxin crystal. N-terminal sequences of the major δ-endotoxin proteins were compared with the N-terminal sequences of the 80 kDa and 35 kDa VIP and revealed no sequence homology. The N-terminal sequence of the vip3A(a) insecticidal protein posses a number of positively charged residues (from Asn2 to Asn7) followed by a hydrophobic core region (from Thr8 to Ile34). Unlike most of the known secretion proteins, the vip3A(a) insecticidal protein from strain AB88 is not N-terminally processed during export.

0197The <i>Ostrinia nubilalis</i> activity is due to a 60 kDa VIP and the <i>Spodoptera frugiperda</i> activity is due to a VIP of unknown size.

<u>EXAMPLE 7. CLONING OF THE VIP3A(a) and VIP3A(b) GENES WHICH ENCODE PROTEINS ACTIVE AGAINST BLACK CUTWORM.</u>

0202Total DNA from isolates AB88 and AB424 was isolated [Ausubel et al (1988), in: Current Protocols in Molecular Biology (John Wiley &amp; Sons, NY)] and digested with the restriction enzymes <i>Xba</i>l [library of 4.0 to 5.0 Kb size-fractionated <i>XbaI</i> fragments of <i>B thuringiensis</i> AB88 DNA] and <i>EcoR</i>I [library of 4.5 to 6.0 Kb size-fractionated <i>EcoRI</i> fragments <i>B thuringiensis</i> AB424 DNA] respectively, ligated into pBluescript vector previously linearized with the same enzymes and dephosphorylated, and transformed into <i>E. coli</i> DH5α strain. Recombinant clones were blotted onto nitrocellulose filters which were subsequently probed with a ³² P labeled 33-bases long oligonucleotide corresponding to the 11-N terminal amino acids of the 80 kDa protein active against <i>Agrotis ipsilon</i> (black cutworm). Hybridization was carried out at 42°C in 2 x SSC/0.1% SDS (1 x SSC = 0.15 m NaCl/0.015 M sodium citrate, pH 7.4) for 5 min and twice at 50°C in 1 x SSC/0.1 SDS for 10 min. Four out of 400 recombinant clones were positive. Insect bioassays of the positive recombinants exhibited toxicity to black cutworm larvae comparable to that of AB88 or AB424 supernantants.

0203Plasmid pCIB7104 contains a 4.5 Kb <i>XbaI</i> fragment of AB88 DNA. Subclones were constructed to define the coding region of the insecticidal protein.

0204<i>E coli</i> pCIB7105 was constructed by cloning the 3.5 Kb <i>XbaI-AccI</i> fragment of pCIB7104 into pBluescript.

0205Plasmid pCIB7106 contained a 5.0 Kb <i>EcoRI</i> fragment of AB424 DNA. This fragment was further digested with <i>HincII</i> to render a 2.8 kb <i>EcoRI-HincII</i> insert (pCIB7107), which still encoded a functional insecticidal protein.

0206The nucleotide sequence of pCIB7104, a positive recombinant clone from AB88, and of pCIB7107, a positive recombinant clone from AB424, was determined by the dideoxy termination method of <nplcit id="ncit0049" npl-type="s"><text>Sanger et al., Proc. Natl. Acad. Sci. USA, 74: 5463-5467 (1977)</text></nplcit>, using PRISM Ready Reaction Dye Deoxy Terminator Cycle Sequencing Kits and PRISM Sequenase® Terminator Double-Stranded DNA Sequencing Kit and analysed on an ABI 373 automatic sequencer.

0207The clone pCIB7104 contains the VIP3A(a) gene whose coding region is disclosed in SEQ ID NO:1 and the encoded protein sequence is disclosed in SEQ ID NO:2. A synthetic version of the coding region designed to be highly expressed in maize is given in SEQ ID NO:3. A fusion between synthetic and native sequences is disclosed in SEQ ID NO: 6. Any number of synthetic genes can be designed based on the amino acid sequence given in SEQ ID NO:2.

0208The clone pCIB7107 contains the VIP3A(b) gene whose coding region is disclosed in SEQ ID NO:4 and the encoded protein is disclosed in SEQ ID NO:5. Both pCIB7104 and pCIB7107 have been deposited with the Agricultural Research Service Patent Culture Collection (NRRL) and given Accession Nos. NRRL B-21422 and B-21423, respectively.

0209The VIP3A(a) gene contains an open reading frame (ORF) that extends form nucleotide 732 to 3105. This ORF encodes a peptide of 791 amino acids corresponding to a molecular mass of 88,500 daltons. A Shine-Dalgarno (SD) sequence is located 6 bases before the first methionine and its sequence identifies a strong SD for <i>Bacillus</i>.

0210The VIP3A(b) gene is 98% identical to VIP3A(a).

0211When blost of total DNA isolated from AB88 <i>B thuringiensis</i> cells were probed with a 33.base fragment that spans the N-terminal region of the VIP3A-insecticidal protein, single bands could be observed in different restriction digests. This result was confirmed by using larger probes spanning the coding region of the gene. A search of the GenBank data base revealed no homology to known proteins.

<u>EXAMPLE 8. EXPRESSION OF THE VIP3A INSECTICIDAL PROTEINS</u>

0212The time course for expression of the VIP3A(a) insecticidal protein was analyzed by western blot. Samples from <i>Bacillus thuringiensis</i> Ab88 clutures were taken throughout ist growth curve and sporulation. The VIP3A(a) insecticidal protein can be detected in the supernatants of AB88 cultures during logarithmic phase, as early as 15 h after initiating the culture. It reached its maximum level during early stages of stationary phase and remained at high levels during and after sporulation. Similar results were obtained when supernatants of AB424 <i>Bacillus cereus</i> cultures were used. The levels of VIP3A(a) insecticidal protein reflected the expression of the VIP3A(a) gene as determined by Northern blot. The initiation of the sporulation was determined by direct microscopic observations and by analyzing the presence of δ-endotoxins in cell pellets. Cry-I type prtoeins could be detected late in the stationary phase , during and after sporulation.

<u>EXAMPLE 9. IDENTIFICATION OF NOVEL VIP3-LIKE GENES BY HYBRIDIZATION</u>

0213To identify <i>Bacillus</i> containing genes related to the VIP3A(a) from isolate AB88, a collection of <i>Bacillus</i> isolates was screened by hybridization. Cultures of 463 <i>Bacillus</i> strains were grown in microtiter wells until sporulation. A 96-pin colony stampel was used to transfer the cultures to 150 mm plates containing L-agar. Inoculated plates were kept at 30°C for 10 hours, then at 4°C overnight. Colonies were blotted onto nylon filters and probed with a 1.2Kb <i>Hin</i>dIII VIP3A(a) derived fragment. Hybridization was performed overnight at 62°C using hybridization conditions of Maniatis <i>et al</i>. <u>Molecular Cloning: A Laboratory Manual</u> (1982). Filters were washed with 2xSSC/0.1% SDS at 62°C and exposed to X-ray film.

0214Of the 463 <i>Bacillus</i> strains screened, 60 contain VIP3-like genes that could detected by hybridization. Further characterization of some of them (AB6 and AB426) showed that their supernatants contain a BCW insecticidal protein similar to the Vip3 protein that are active against black cutworm.

<u>EXAMPLE 10. CHARACTERIZATION OF A <i>B. thuringiensis</i> STRAIN M2194 CONTAINING A CRYPTIC VIP3-LIKE GENE</u>

0215A <i>B. thuringiensis</i> strain, designated M2194, was shown to contain VIP3-like gene(s) by colony hybridization as described in Example 8. The M2194 VIP3 like gene is considered cryptic since no expression can be detected throughout the bacterial growth phases either by immunoblot analysis using polyclonal antibodies raised against the VIP3A(a) protein isolated from AB88 or by bioassay as described in Example 2. Antiserum against purified VIP3A(a) insecticidal protein was produced in rabbits. Nictrocellulose-bound protein (50 µg) was dissolved in DMSO and emulsified with Freund's complete adjuvant (Difco). Two rabbits were given subcutaneous injections each month for three month. They were bled 10 days after the second and third injection and the serum was recovered from the blood sample [Harlow et al (1988) in : Antibodies: A Laboratory Manual (Cold Spring Harbor Lab Press, Plainview, NY)].

0216The M2194 VIP3-like gene was cloned into pKS by following the protocol described in Example 3, which created pCIB7108. <i>E. coli</i> containing pCIB7108 which comprises the M2194 VIP3 gene were active against black cutworm demonstrating that the gene encodes a functional protein with insecticidal activity. The plasmid pCIB7108 has been deposited with the Agricultural Research Service Patent Culture Collection (NRRL) and given Accession No. NRRL B-21438.

<u>EXAMPLE 11. INSECTICIDAL ACITIVITY OF VIP3A PROTEINS</u>

0217The activity spectrum of VIP3A insecticidal proteins was qualitatively determined in insect bioassays in which recombinant <i>E coli</i> carrying the VIP*A genes were fed to larvae. In these assays, cells carrying the VIP3A(a) and VIP3A(b) genes were insecticidal to <i>Agrotis ipsilon, Spodoptera frugiperda, Spodoptera exigua, Heliothis virescens</i> and <i>Helicoverpa zea.</i> Under the same expermimental conditions, bacterial extracts containing VIP3A proteins did not show any activity against <i>Ostrinia nubilalis.</i><tables id="tabl0025" num="0025"><table frame="all"><tgroup cols="2" rowsep="0"><colspec colnum="1" colname="col1" colwidth="47mm" /><colspec colnum="2" colname="col2" colwidth="41mm" /><thead valign="top"><row rowsep="1"><entry namest="col1" nameend="col2" align="left">Effect of VIP*A insecticidal proteins on <i>Agrotis ipsilon</i> larvae</entry></row><row rowsep="1"><entry>Treatment</entry><entry>(%) Mortality</entry></row></thead><tbody><row><entry>TB medium</entry><entry align="right">5</entry></row><row><entry>AB88 Supernatant</entry><entry align="right">100</entry></row><row><entry>Ab424 Supernatant</entry><entry align="right">100</entry></row><row><entry>Buffer</entry><entry align="right">7</entry></row><row><entry><i>E coli</i> pKS</entry><entry align="right">10</entry></row><row><entry><i>E coli</i> pCIB7104 (AB88)</entry><entry align="right">100</entry></row><row><entry><i>E coli</i> pCIB7105 (AB88)</entry><entry align="right">100</entry></row><row><entry><i>E coli</i> pCIB7106 (AB424)</entry><entry align="right">100</entry></row><row rowsep="1"><entry><i>E coli</i> pCIB7107 (AB424)</entry><entry align="right">100</entry></row></tbody></tgroup></table></tables><tables id="tabl0026" num="0026"><table frame="all"><tgroup cols="3" rowsep="0"><colspec colnum="1" colname="col1" colwidth="54mm" /><colspec colnum="2" colname="col2" colwidth="56mm" /><colspec colnum="3" colname="col3" colwidth="57mm" /><thead valign="top"><row rowsep="1"><entry namest="col1" nameend="col3" align="left">Effect of VIP3A insecticidal proteins on lepidopteran insect larvae</entry></row><row rowsep="1"><entry>Treatment</entry><entry>Insect</entry><entry>(%) Mortality</entry></row></thead><tbody><row><entry><i>E coli</i> pKS</entry><entry>BCW</entry><entry align="right">10</entry></row><row><entry /><entry>FAW</entry><entry align="right">5</entry></row><row><entry /><entry>BAW</entry><entry align="right">10</entry></row><row><entry /><entry>TBW</entry><entry align="right">8</entry></row><row><entry /><entry>CEW</entry><entry align="right">10</entry></row><row><entry /><entry>ECB</entry><entry align="right">5</entry></row><row><entry /><entry /><entry /></row><row><entry><i>E coli</i> pCIB7105</entry><entry /><entry /></row><row><entry><i>E coli</i> pCIB7107</entry><entry>BCW</entry><entry align="right">100</entry></row><row><entry /><entry>FAW</entry><entry align="right">100</entry></row><row><entry /><entry>BAW</entry><entry align="right">100</entry></row><row><entry /><entry>TBW</entry><entry align="right">100</entry></row><row><entry /><entry>CEW</entry><entry align="right">50</entry></row><row rowsep="1"><entry /><entry>ECB</entry><entry align="right">10</entry></row><row rowsep="1"><entry namest="col1" nameend="col3" align="justify">BCW = Black Cut Worm; FAW = Fall Army Worm; BAW = Beet Army Worm; TBW = Tobacco Bud Worm; CEW = Corn Ear Worm; ECB = European Corn Borer</entry></row></tbody></tgroup></table></tables>
