Phylogenetic analysis of viruses in Tuscan Vitis vinifera sylvestris (Gmeli) Hegi.

PLoS ONE, 2018
The health status of the native grapevine Vitis vinifera subsp. sylvestris (Gmeli) Hegi in natural areas in Europe has received little attention. A survey was carried out on wild grapevines in Tuscany (Italy), where isolates of the Grapevine rupestris ...

Genetic variants of Grapevine leafroll-associated virus 2 infecting Portuguese grapevine cultivars

Phytopathologia Mediterranea, 2016
Genetic variability of 19 isolates of Grapevine leafroll-associated virus 2 (GLRaV-2) from Portuguese grapevine cultivars was characterized by sequencing the entire capsid protein (CP) gene of the virus. Global phylogenetic analysis of the CP gene, which

Introduction of Grapevine virus B and Grapevine leafroll-associated virus 2 testing in sanitary selection of grapevine

Acta Agriculturae Slovenica, 2008
To introduce testing of Grapevine leafroll-associated virus-2 (GLRaV-2) and Grapevine virus B (GVB) in sanitary selection of grapevine, commercially available antibodies were evaluated and conditions for routine ELISA testing were optimized.

Grapevine Leafroll Disease Control: It Pays to Test Neighboring Vines

, 2014
The economics of grapevine leafroll control through vine replacement has a spatial component.  A new model by Shady Atallah and Miguel Gomez demonstrates that testing vines adjacent to those with leafroll symptoms and replacing them if they test positive
