Golino cautions that many more new viruses and other microbes are likely to be found in grapevines in the next few years to add to the list of more than 75 graft-transmissible agents that have been identified in grapevines, thanks to powerful new DNA sequencing technology. "Some of those will be disease agents, some beneficial, and some neutral," she explains. "We will have our work cut out for us in understanding the role of these microbes, but the ultimate result will be increased ability to create superior grapevine material." "The appearance of red blotch virus," says John Aguirre, president of California Association of Wine grape Growers, "underscores the vital importance of the Foundation Plant Services and adequate funding for the U.S. Department of Agriculture's (USDA) National Clean Plant Network. Growers need clean plant material to meet winery demands for increased wine grape production and improved quality." Progress on identifying and characterizing red blotch has been a collaborative effort between many USDA-ARS and university-based researchers over several years, notes Golino. Golino announced that California rootstock nurserymen acted in February to assist the California viticulture industry with research addressing GRBaV. The California Grape Rootstock Research Foundation, which funds research to enhance California viticulture and the grape nursery industry, has agreed to provide seed money to jumpstart research on the virus.
