Weidong Chen
Research Plant Pathologist,
USDA ARS/ Adjunct Professor
Research Specialty and Interests
Dr. Weidong Chen's research focuses on diseases of grain legumes (peas, chickpeas and lentils).
His research interests encompass applied research such as epidemiology and management of grain legume diseases using host resistance, cultural practices and chemical control, and basic research on mechanisms of pathogenicity using insertional mutagenesis and fuctional genomics. Collaborating with plant geneticists, Dr. Weidong Chen is also involved in development of molecular markers for host resistance using comparative genetics and genomics. His current research projects are on Ascochyta blight (Ascochyta rabiei) of chickpea, white mold (Sclerotinia sclerotiorum) of peas and lentils, and powdery mildew (Erysiphe pisi) of peas.
