A new discovery by Washington State University scientists could help grape growers roll back a devastating virus that withers vines and shrivels harvests.
Named for how it curls the leaves of infected plants, grapevine leafroll disease costs growers millions of dollars in lost vines and productivity. Until now, no one has been able to replicate one of the main culprits behind the disease, a virus called grapevine leafroll-associated virus 3—leafroll 3, for short.
For the first time, researchers in WSU’s Department of Plant Pathology have found a way to clone leafroll 3, opening the door for experiments and treatments to protect valuable Washington vineyards.
