The present invention relates to compositions and methods for enhancing plant defenses against pathogens. More particularly, the invention relates to enhancing plant immunity against bacterial pathogens, wherein AtMIN7 mediated protection is enhanced and/or there is a decrease in activity of an AtMIN7 associated virulence protein such as a Pseudomonas syringae pv. tomato DC3000 HopM1. Reagents of the present invention provide a means of studying cellular trafficking while formulations of the present inventions provide increased pathogen resistance in plants.
The invention was made in part with Government support from the Department of Energy and National Institutes of Health, National Institute Of Allergy And Infectious Diseases, grants 1R01AI060761-01A2 and 1R21AI060761-01. As such, the Government has certain rights in the invention.
