Scientists at UC Davis have identified a key protein at the root of a disease likely ravaging California’s grapevines and costing the state’s wine and grape industry more than $100 million yearly. Pierce’s disease is caused by a bacteria known to hurt crops including almonds and grapes. It’s transmitted from vine to vine by a small winged insect called the sharpshooter which lives near rivers and streams.
