Grapevine leafroll-associated virus 3
Grapevine leafroll disease (GLD) is one of the most important grapevine viral diseases affecting grapevines worldwide. The impact on vine health, crop yield, and quality is difficult to assess due to a high number of variables, but significant economic losses are consistently reported over the lifespan of a vineyard if intervention strategies are not implemented. Several viruses from the family...
متن کاملOccurrence of Grapevine Leafroll-Associated Virus Complex in Napa Valley
Grapevine leafroll disease (GLD) is caused by a complex of several virus species (grapevine leafroll-associated viruses, GLRaV) in the family Closteroviridae. Because of its increasing importance, it is critical to determine which species of GLRaV is predominant in each region where this disease is occurring. A structured sampling design, utilizing a combination of RT-PCR based testing and sequ...
متن کاملGenomic Sequence and Organization of a Grapevine Virus: Grapevine Asteroid Mosaic-associated Virus
The usefulness of repetitive transcranial magnetic stimulation (rTMS) as a neuro-rehabilitation adjunct is currently limited by the high inter-individual variability in its effects. In order to advance the use of this technology for those who experience brain damage, it is important to identify biomarkers that could be used to predict which individuals would have a good response to rTMS. In thi...
متن کاملSeasonal dynamics and virus translocation of Grapevine leafrollassociated virus 3 in grapevine cultivars
Grapevine leafroll-associated virus 3 (GLRaV-3) is associated with grapevine leafroll disease, one of the most economically important viral diseases of grapevines. This disease impacts on both vine health and grape quality; reduction in yield, brix and wine colour are among its detrimental effects. Many methods, including serological and molecular procedures, have been developed for the detecti...
متن کاملElimination of Grapevine leafroll associated virus-3, Grapevine rupestris stem pitting associated virus and Grapevine virus A from a Tunisian Cultivar by Somatic Embryogenesis and Characterization of the Somaclones Using Ampelographic Descriptors
Prospecting of local grapevine (Vitis vinifera L.) germplasm revealed that Tunisia possesses a rich patrimony which presents diversified organoleptic characteristics. However, viral diseases seriously affect all local grapevine cultivars which risk a complete extinction. Sanitation programs need to be established to preserve and exploit, as a gene pool, the Tunisian vineyards areas. The presenc...
