Ph.D., Ohio State University, 1957

Curriculum Vitae

My research is focused on bacteria that cause plant disease. The bacterial spot disease of pepper and tomato cause by Xanthomonas campestris pv. vesicatoria is used as a model to study pathogenicity. I am interested in the mechanism of hypersensitivity as a system that determines the specificity of the bacteria-plant interaction. My present approach is to use genetic recombination techniques to isolate the avirulence genes involved in the interaction. I am also involved in studying the genetic diversity within thes bacterium by using fatty acid analyses, endonuclease restriction profiles, and DNA homology. I also teach the course "Bacterial Plant Pathogens".
