Abstract
The invention provides nucleic acids, polypeptides, transgenic plants, compositions and methods for conferring pesticidal activity (e.g., insecticidal activity) to bacteria, plants, plant cells, tissues and seeds. Nucleic acids encoding the insecticidal proteins can be used to transform prokaryotic and eukaryotic organisms to express the insecticidal proteins. The recombinant organisms or compositions containing the recombinant organisms or insecticidal proteins or in combination with an appropriate agricultural carrier can be used to control an insect pest in various environments.
Claims24
A chimeric insecticidal protein that is toxic to a lepidopteran insect pest comprising in an N-terminal to C-terminal direction:
- (a) an N-terminal region of a first Cry1 protein, which is an N-terminal region of a BT-0029 protein of SEQ ID NO:2 or an amino acid sequence that is at least 90% identical thereto, fused to
- (b) a C-terminal region of a different Cry1 protein;
- wherein a crossover position between the first Cry1 protein and the different Cry1 protein is located in conserved block 3.
