Research Interests

 

Our research is focused on the comparative and functional genomics of disease resistance in plants, particularly Arabidopsis, tomato and lettuce. Our investigations of Arabidopsis involve the large-scale genomic analysis of resistance gene function and evolution in Arabidopsis as well as a comparative genomics analysis of resistance across multiple species. Our studies of disease resistance in tomato focus on structure-function analyses on the resistance gene Pto, Prf and dissection of the Pto-mediated disease resistance signaling pathway. Studies on lettuce and its pathogens includes classical studies of disease resistance, development of detailed genetic maps using molecular markers, studies on transgene expression and characterization of resistance genes at the molecular level. All of these projects are supported by the lab bioinformatics group.
