Research

  • The emphasis of Dr. Evans' research is on the identification, etiology and control of virus and fungal diseases of vegetable and field crops. A major focus of his research is to provide a better understanding of how plants respond to infection at the cellular and molecular level. The main goal of his work is to reduce crop losses through a better understanding of epidemics and the development of resistance. Dr. Evans' laboratory currently works on the characterization of new races of the pathogen Phytophthora phaseoli, the causal agent of downy mildew of lima bean. Additionally his group is working on the development of resistant cultivars, and is developing a better understanding of the epidemiology of the disease and chemical and cultural methods of for its control. A new focus of his program is the evolution and functional genomics of P. phaseoli.
