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.
