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.
UC Davis received a $500K grant to breed drought-tolerant and disease-resistant carrots using wild genetics. Researchers aim to reduce fungicide use and secure crop yields, ensuring a stable carrot supply for growers and consumers.
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.
