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 HopM1.sub.1-300 mediated protection is enhanced, such as increased protection to Pseudomonas syringae pv. tomato DC3000 HopM1 and/or there is an increase in activity of an ATMIN associated plant protection protein, such as ATMIN7. Reagents of the present invention further 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 IR01AI060761-01A2 and IR21AI060761-01. As such, the Government has certain rights in the invention.
