Identification of new genes that control plant defense responses. We are examining both SAR and SAR-independent resistance pathways, because both appear to play important roles in defense. Investigation of the interplay between plants and biotrophic fungal pathogens. The relative roles of both plant and pathogen in these interactions is complex and poorly understood. We hope the gain understanding through molecular genetic experiments and cytological methods.
New mutants provide clues into regulation of systemic acquired resistance.
