Bacillus thuringiensis crystal protein gene toxin segment

摘要

A DNA fragment that codes for the portion of Bacillus thuringiensis crystal protein peptide that is toxic to lepidopteran insects. The invention also comprises the DNA and amino acid sequences for the disclosed toxin-encoding DNA fragment. In addition the invention demonstrates that the disclosed toxin-encoding DNA fragment (referred to herein as the Bacillus thuringiensis crystal protein gene toxin segment) is expressible in recombinant host organisms, and that the "toxin" protein product produced by the transformed hosts is toxic to lepidopteran insects.
