- Grapevine leafroll-associated virus (GLRaV) is a name for a group of viruses that infect grapevine. Obscure mealybugs (Pseudococcus viburni) feed on the phloem of vines and woody-stemmed plants, especially pear and apple trees and grape vines. Some individuals are vectors for infectious pathogens and can transmit them from plant to plant while feeding; mealybug-spread grapevine leafroll associated virus type III (GRLaV-3), in particular, has wreaked havoc among the grapes of New Zealand, reducing the crop yield of infected vineyards by up to 60%. The biggest problems in Grapevine Leafroll Disease are reduced grape yield, altered grape ripening, and altered grape chemistry. Leafroll viruses are associated with rugose wood condition of grapevine. (en)
- La maladie de l'enroulement de la vigne est une maladie virale qui affecte les plantes du genre Vitis, notamment la vigne (Vitis vinifera). Elle est causée par un complexe viral comprenant plusieurs espèces appelées « virus associés de l'enroulement de la vigne » (GLRaV, Grapevine leafroll-associated virus) appartenant aux genres Ampelovirus, Closterovirus et Velarivirus (famille des Closteroviridae). Ce sont des virus à ARN simple brin à polarité positive, et donc à ce titre classés dans le groupe IV de la classification Baltimore. (fr)
