A scraggly grapevine collected in 1906 and stored at the UC Davis Center for Plant Diversity Herbarium has yielded clues to when Pierce's disease arrived in California and how the bacterium that causes it has evolved since then. Scientists hope to use that information to prevent and, eventually, treat the deadly blight, which has spread to wine-growing regions around the world.
The Foundation for Food & Agriculture Research has awarded a $500,000 grant to the University of California, Davis, to tap into the genetic diversity of wild carrots. They hope to breed Alternaria resistance and the ability to grow in water-deficient conditions into commercial varieties.
Advances in breeding and postharvest handling in strawberries and tomatoes, aimed at reducing the costs of disease in the field and in postharvest, were on display at the recent Strawberry Disease Field Day, hosted by the UC Davis Strawberry Breeding Program.
