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.
