Project Number: 5302-22000-008-00
Project Type: Appropriated

Start Date: Mar 15, 2007
End Date: Mar 14, 2012

Objective:
The overall goals of this project are to reduce losses due to Xf-caused diseases during crop production and to develop effective, sustainable disease and insect vector management strategies by characterizing the host-pathogen-vector-environment interactions of these complex pathosystems. Specific objectives for the project are outlined below: Objective 1: Determine the epidemiology of exotic, emerging, re-emerging, and invasive diseases in California, including (but not necessarily limited to) Xf-caused diseases of horticultural, agronomic, and ornamental crops. Objective 2: Determine the nature and mechanism(s) of susceptibility/resistance to Xf infection and subsequent disease development in horticultural and agronomic crops, including (but not necessarily limited to) Vitis species and Prunus species. Objective 3: Develop effective, economical, environmentally sound strategies to manage exotic, emerging, re-emerging, and invasive diseases, including (but not necessarily limited to) xylella diseases.

Approach:
Determine the epidemiology of Xylellae diseases in California. Characterize the complex host-pathogen-insect vector-environment interactions of these pathosystems. Determine the biochemical, physiological, genetic and mechanistic bases of resistance to XF infection and subsequent disease development in Vitis and selected Prunus species.
