Jianjun (Jay) Hao
Assistant Professor of Plant Pathology
Degree: Ph. D. 2000, University of California-Davis
Location: 174 Hitchner Hall
Professional Interests: Plant-pathogen interaction, phytobiome related to plant health, biological control and fungicide resistance.
Teaching: PSE457 Plant Pathology / PSE557 Advanced Plant Pathology; SFA551 Infectious Diseases and Food Safety- From Plants to Humans.
Research: My research is focused on the epidemiology and management of potato diseases. Major diseases include bacterial soft rot and blackleg (Dickeya and Pectobacterium spp.), common scab (Streptomyces spp.), late blight (Phytophthora infestans),and pink rot (Phytophthora erythroseptica). I am interested in microbiomes that are associated with soil and plant health, and beneficial microorganisms (or biological control agents) for managing plant diseases. We are studying signal molecules that regulate the behavior of P. erythroseptica and factors inducing viable but nonculturable state that is related to bacterial dormancy.
