Newsheadline bar **Recent Accomplishments for the Crops Pathology/Genetics Research Center include:** **Crops Pathology** Graft inoculated 47 collections across nine different test plants to demonstrate the importance of post grafting temperature on cullus formation and uniting buds and test plants.
Demostrated that saturated soils induced greater incidence of union mild etch on almond trees.
Discovery of uncharacterized graft transmissible agent (GTA) in Clone 8 of C. Sauvignon.
Established field trials to characterize new GTA.
Completed seven field trials to identify Methyl Bromide Alternatives to control Almond replant disease.
Completed Parlier microplot studies to identify etiology of Almond replant disease and establish mitigation measures.
Determined efficacy of Phosphonate application for control of Phytophthora canker on almond.
Developed Methyl Bromide alternative for Phytophthora control on strawberry.
Identified walnut root stocks resistant to Phytophthora.
Developed a culture independent method for detection of Agrobacterium tumefaciens. **Rice Genetics** Completed genotyping phase of NRI-funded project. Molecular evaluation of rice germplasm using microsatellite markers.
Continued to examine new microsatellite markers (renewed CRADA with Syngenta AG.
Fine mapped the low phytic acid 1-1 locus to a 140 kb region of rice chromosome 2 and fine conducted screen for additional low phytic acid rice mutants.
Initiated genetic analysis of stem rot resistance in rice.
Continued genetic analysis of cold tolerance in rice.
Conducted screen for low silicon rice mutants. **Sustainable Viticulture** Established field plots to examine significance of riparian plants in the epidemiology of Pierce's Disease.
Demonstrated efficacy of root collar excavation for control of armillaria root disease of grapevine.
Discovered that arbuscular mycorrhizal fungal populations in the vineyard are significantly reduced when rootstocks were propagated in the greenhouse and when weed populations are suppressed.
