Research Interests:

Our research is directed primarily toward virus-host interactions. Our work includes genetic and physiological characterization of naturally occurring potyvirus resistances in cucumber including expression of resistance alleles, interaction with viral protein domains, viral and host determinants of systemic infection, viral host range, and identification of host factors that directly interact with viral proteins.

Other research efforts include study of the molecular basis of sex expression in Cucumis and Phytopthora infection of cucumber. We have developed transformation systems for cucumber and melon and have introduced several genes for virus resistance, sex expression, and abiotic stress resistance. We also are involved in examination of risks associated with transgenic crops.
