New Insight Into Why Pierce’s Disease is So Deadly to Grapevines: Research could help diagnose disease early and increase plant health

Scientists are gaining a better understanding of Pierce’s disease and how it affects grapevines. The disease, which annually costs California more than $100 million, comes from a bacterium called Xylella fastidiosa. While the bacterium has been present in the state for more than 100 years, Pierce’s disease became a more serious threat to agriculture with…

Newly Identified Enzyme May Be the Culprit in Pierce’s Disease Grapevine Damage

January 12, 2016 UC Davis plant scientists have identified an enzyme that appears to play a key role in the insect-transmitted bacterial infection of grapevines with Pierce’s disease, which annually costs California’s grape and wine industries more than $100 million. The researchers hope that the discovery, which runs counter to existing theories, will lead to…
