MODIFIED CRY1CA INSECTICIDAL CRY PROTEINS

摘要

The present invention includes modified, insecticidal B.t. Cry1Ca proteins, including the proteins designated herein as DIG-109 and DIG-152, as well as variants of DIG-109 and DIG-152, nucleic acids encoding these proteins, methods of controlling pests using the proteins, methods of producing the proteins in transgenic host cells, and transgenic plants that produce the proteins. The DIG-109 and DIG-152 proteins comprise chimeric peptides composed of a core toxin segment of B.t. Cry1Ca and a Cry1Ab protoxin segment. Insecticidally active variants of the DIG-109 and DIG-152 proteins are also described.
