Arabidopsis is universally resistant as a species to many crop pathogens, including examples from other crucifers suchas Albugo candida and Hyaloperonospora parasitica from Brassica oleracea. This species level trait could potentiallyprovide a source of durable disease resistance in crops if examples can be found which are amenable to molecular geneticcharacterization. Our research has developed from the observation that null mutation in Arabidopsis of a defense regulatorygene EDS1 (enhanced disease susceptibility) is susceptible to isolates of A. candida and H. parasitica from brassica.EDS1 is required by a major structural class of R-genes to confer resistance in Arabidopsis. We have therefore focusedon identifying R-genes in Arabidopsis that are responsible for conferring resistance to brassica pathogens.
