A gene fusion research project led by a University of California, Davis, plant scientist delivers a one-two punch to Pierce's disease, a deadly threat to California's world-renowned wine industry.
The Fresh Fruits Magazine Pomology.org has newly included the category Grape to its collection of crops.
Predictions of grape yields are extremely important to juice processors and wineries; timely and precise yield forecasts allow producers to plan for harvest and move the highly perishable grape crop from vine to processing efficiently.
Could point the way toward production of European-tasting wines from American vines.
Genetic engineering could make grapevines immune to a common virus that now results in smaller grapes and crop loss, German scientists said. Modified plants have produced antibodies against Grapevine fanleaf virus, caused by the vine louse, or rust mite, researchers at the Institute for Molecular Biology and Applied Ecology, in Aachen, said. These antibodies 'recognize' the viruses and prevent them from spreading in the plant and causing damage, said Dr.
Viruses can cost winegrowers an entire harvest. If they infest the grapevines, even pesticides are often no use. Whatâ€™s more, these chemicals are harmful to the environment.
Canadian researchers say they've determined the scent of grapevine flowers comes from pollen grains stored in the anthers, not just the petals. University of British Columbia scientists from the school's Wine Research Center and Michael Smith Laboratories were studying grapes used to produce Cabernet Sauvignon from British Columbia's Okanagan region when they identified a gene that produces and regulates fragrance from the vines' tiny clusters of green blossoms. This was a surprise in...
Missouri State University researchers hope to apply genetic technology to make cultivated wine grapes as hardy as their wild cousins.
