Research Interests

Current research in the lab focuses on reproductive (flower and fruit) development in Cucumis (cucumber and melon).  We are particularly interested in understanding the role of ethylene production, perception, and signaling in regulation of unisexual flower development using a combination of molecular genetic and transgenic approaches.  Our questions regarding fruit development focus on early stages of fruit growth and factors influencing fruit size, shape, and resistance to infection by Phytophtora capcisi.

 A second long-term area of interest is biotechnology biosafety.  Activities in this area include risk assessment research, textbook development, teaching, and international development work, including participation in MSU, USAID, and the Bill and Melinda Gates Foundation-based projects.

Program Areas

Plant Breeding and Genetics

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.
