ABSTRACT:
Compositions and methods for controlling pests, particularly insect pests, are provided. The compositions comprise proteins isolated from plants of the genus Pentaclethra which exhibit trypsin inhibiting activity. Nucleotide sequences encoding the proteins are also provided. Such sequences find use in transforming organisms for control of pests.
