ANTIFUNGAL CHITIN BINDING PROTEINS AND DNA CODING THEREFOR

摘要

A new category of antifungal chitin binding proteins (antifungal CBPs) is provided with very low chitinase activity (10 % or less than that of the class-1 chitinases from tobacco). Also substantially pure DNA sequence-C encoding antifungal CBP and plant expressile antifungal CBP genes are provided for the obtention of transgenic plants producing antifungal CBP. Plants expressing an antifungal CBP gene, optionally in combination with a plant expressible glucanase gene, show reduced susceptibility to fungi.
