Abstract

A major resource in the drive to reduce chemical pesticide usage and to generate pest- resistant transgenic plants are the insecticidal proteins (delta-endotoxins) produced by Bacillus thuringiensis. Development of this resource by industry and plant breeders requires an understanding at the molecular level of factors determining the potency of these protein pesticides. We have solved the X-ray structures of representatives of the two (Cry and cyt) toxin families. This structural database, plus our experience of toxin mutagenesis, and our traditional and novel assays for quantifying toxin potency provides a unique opportunity to propose a comprehensive programme to discover the contribution of potency of each step in the insecticidal mechanism and thereby to design protocols to engineer these proteins for enhanced potency for transgenic plant expression and field application.
