Area of Specialization

Genetic, biochemical and molecular analysis of plant-microbe interactions: mycotoxins, programmed cell death in plant disease, diseases of agronomic crops.

Research

Research is focused in two areas: 1) genetic regulation and biochemical response of plants to infection and 2) signals and signal transduction pathways leading to the activation of apoptosis in plant disease. The latter includes a proteomic approach to the assessment of factors that control apoptotic cell death in both resistant and susceptible reactions of plants to pathogens. Topical areas involve the functional analysis and cloning of genes, which regulate apoptosis in plants and the biosynthesis and mode of action of mycotoxins in plant and animal diseases. Host emphasis in these analyses is on diseases of grape and tomato.
