Sad-looking Herbarium specimen yields clues to wine country blight

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.

WeedChat: An AI-powered chatbot answers thorny questions

Mohsen Mesgaran, at the UC Davis Department of Plant Sciences, and team are developing a chatbot powered by artificial intelligence to help growers, backyard gardeners, landowners and others identify and treat weeds. The state Department of Food and Agriculture is funding the project with a grant of nearly $430,000. The development is expected to take two years.

Gene “boosts” hope for plant-based jet fuel, plentiful food

A team of scientists, including Gail Taylor of the UC Davis Department of Plant Sciences, has identified a gene in poplar trees that enhances photosynthesis and can boost tree height by as much as 200 percent. Discovery of the “Booster” gene has enormous potential for both the nation’s efforts to create plant-based jet fuel and to boost the yield of key food crops.
