Methods and compositions for making and using compatible insecticidal proteins

Abstract

Pesticidal proteins (FFPP's) are used to produce derivatives (DP's) that are ineffective and disabled relative to conferring toxic properties upon a target pest, yet the ability of the DP to bind to the receptor to which said FFPP binds is unaffected. Such DP's are useful in inhibiting the FFPP from which it was derived when both are fed to a target pest and for comparing receptor binding capability and efficiency relative to different FFPP's from which the DP has been derived, providing for an assessment of different FFPP's relative to each other, and providing uniformity and certainty in combinations of such FFPP's for compositions, including transgenic plants, that can be used to control pest populations susceptible to both FFPP's, creating more durable transgenic plant products, inhibiting the development of resistance to such FFPP's when used in plants commercially, and in providing a durable and viable resistance management strategy for crops using such FFPP combinations. Polynucleotide sequences intended for use in expression of the DP's and FFPP's are also provided. Particular embodiments provide methods of designing and preparing DP's, as well as compositions and methods of using DP's and the FFPP's from which the DP's have been derived in more effective pesticidal compositions and products.
