Abstract: Disclosed are novel insecticidal polypeptides, and compositions comprising these polypeptides, peptide fragments thereof, and antibodies specific therefor. Also disclosed are vectors, transformed host cells, and transgenic plants that contain nucleic acid segments that encode the disclosed &dgr;-endotoxin polypeptides. Also disclosed are methods of identifying related polypeptides and polynucleotides, methods of making and using transgenic cells comprising these polynucleotide sequences, as well as methods for controlling an insect population, such as Colorado potato beetle, southern corn rootworm and western corn rootworm, and for conferring to a plant resistance to a target insect species.

Abstract: Disclosed is a novel &dgr;-endotoxin, designated CryET29, that exhibits insecticidal activity against siphonapteran insects, including larvae of the cat flea (Ctenocephalides felis), as well as against coleopteran insects, including the southern corn rootworm (Diabrotica undecimpunctata), western corn rootworm (D. virgifera), Colorado potato beetle (Leptinotarsa decemlineata), Japanese beetle (Popillia japonica), and red flour beetle (Tribolium castaneum). Also disclosed are nucleic acid segments encoding CryET29, recombinant vectors, host cells, and transgenic plants comprising a cryET29 DNA segment. Methods for making and using the disclosed protein and nucleic acid segments are disclosed as well as assays and diagnostic kits for detecting cryET29 and CryET29 sequences in vivo and in vitro.

Abstract: The present invention is based on the discovery, isolation, sequencing and characterization of two protease genes present in B.t. One is an alkaline protease gene generally designated "apr." The other is a neutral protease gene generally designated "npr." The invention also includes genetically disabling the apr and the npr genes to reduce proteolytic activity of the proteases encoded by the genes, and using the disabled genes in insecticidal B.t. constructs along with one or more B.t. protein toxin genes. These resulting B.t. constructs are useful for the enhanced production of B.t. toxin protein. The B.t. toxin protein recovered from the fermentation production of these B.t. constructs also exhibits improved stability with respect to its insecticidal activity.

Abstract: A Bacillus thuringiensis strain isolate, designated B.t. strain EG5847, exhibits insecticidal activity against lepidopteran insects. Two novel toxin genes from B.t. strain EG5847 designated cryET4 and cryET5 produce insecticidal proteins with activity against a broad spectrum of insects of the order Lepidoptera, The cryET4 gene has a nucleotide base sequence shown in FIG. 1 and listed in SEQ ID NO:1 and produces a CryET4 gene product having the deduced amino acid sequence shown in FIG. 1 and listed in SEQ ID NO:2. The cryET5 gene has a nucleotide base sequence shown in FIG. 2 and listed in SEQ ID NO:3 and produces a CryET5 gene product having the deduced amino acid sequence shown in FIG. 2 and listed in SEQ ID NO:4.
