摘要

The invention provides nucleic acids obtained from strains of Bacillus thuringiensis encoding -endotoxins having pesticidal activity against insect pests including Lepidoptera. Particular embodiments of the invention provide isolated nucleic acid molecules encoding mutant pesticidal polypeptides, pesticidal compositions, expression cassettes, and transformed microorganisms and plants comprising a nucleic acid molecule of the invention. Such compositions find use in methods for controlling plant pests.
