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.
