Location: Horticultural Crops Research
Project Number: 5358-22000-034-00
Start Date: May 14, 2007
End Date: May 13, 2012
This research will be accomplished through a multifaceted approach integrating the disciplines molecular biology, genomics, population ecology, epidemiology, meteorology, climatology, and microbiology. Initially the project will deal with two recently introduced pathogens, Phytophthora ramorum and Phragmidium violaceum, as well as other Phytophthora, powdery mildew and Botrytis diseases of various horticultural crops. This research project will utilize: novel techniques for rapid and accurate assessment of pathogen presence and abundance in the field; quantitative information on distribution of clones, migration of new strains, degree and rates of out-crossing, and sources of resistance to the introduced pathogens P. ramorum and P. violaceum; elucidation of important genetic traits that impact disease development; and increased understanding of factors influencing disease epidemics that will be used to generate improved disease forecasting models.
