Protection against herbivores
View Patent ↗The present invention relates to genes, proteins and methods comprising molecules that alter amino acid levels. In one embodiment, the present invention relates to altering guanidino substrate hydrolysis activities in plants, arthropods and microorganisms using molecules within the arginase family and other molecules that alter an amino acid levels. In ones embodiment, the present invention relates to altering threonine substrate deamination and dehydration activities in plants, arthropods and microorganisms using molecules within the threonine deaminase family and other molecules that alter amino acid levels. In one embodiment, the present invention relates to using genes, proteins and methods comprising arginase or threonine deaminase for altering the pathophysiology of plants, arthropods and microorganisms. In a preferred embodiment, the present invention relates to altering guanidino substrate hydrolysis activity in plants, arthropods, and microorganisms using arginase. In another preferred embodiment, the invention relates to altering threonine substrated deamination and dehydration activity in plants, arthropods, and microorganisms using threonine deaminase. In some embodiments, the invention related to overexpression and increased activity of arginase, threonine deaminase and a proteinase inhibitor.
