Abstract

A pesticidal protein class exhibiting toxic activity against Coleopteran and Lepidopteran pest species is disclosed, and includes, but is not limited to, TIC7040, TIC7042, TIC7381, TIC7382, TIC7383, TIC7386, TIC7388, and TIC7389. DNA constructs are provided which contain a recombinant nucleic acid sequence encoding the TIC7040, TIC7042, TIC7381, TIC7382, TIC7383, TIC7386, TIC7388, and TIC7389 pesticidal proteins. Transgenic plants, plant cells, seed, and plant parts resistant to Coleopteran and Lepidopteran infestation are provided which contain recombinant nucleic acid sequences encoding the TIC7040, TIC7042, TIC7381, TIC7382, TIC7383, TIC7386, TIC7388, and TIC7389 pesticidal proteins of the present invention. Methods for detecting the presence of the recombinant nucleic acid sequences or the proteins of the present invention in a biological sample, and methods of controlling Coleopteran and Lepidopteran species pests using the TIC7040, TIC7042, TIC7381, TIC7382, TIC7383, TIC7386, TIC7388, and TIC7389 pesticidal proteins are also provided.
