摘要

The disclosure provides nucleic acids, and variants and fragments thereof, derived from bacillus thuringiensis strains encoding variant polypeptides with enhanced pesticidal activity against insect pests, including lepidoptera and coleopteran. Particular embodiments of the disclosure provide isolated nucleic acids encoding pesticidal proteins, pesticidal compositions, DNA constructs and transformed microorganisms and plants comprising a nucleic acid of the embodiments. These compositions find use in methods for pest control, especially plant pests.
