Grapevine leafroll disease (GLRD) is one of the most important viral diseases grapevine worldwide. The aim this study was to investigate prevelance associated virus-1 (GLRaV-1), leafroll-associated virus-2 (GLRaV-2), virus-3 (GLRaV-3), virus 4 (GLRaV-4), and virus-9 (GLRaV-9) in Tokat province Turkey. In 2018, leaf samples one-year-old shoots plants, showing virus-like symptoms, were collected ...

Symptomatic grapevine samples were collected from vineyards in Zanjan province to detect Grapevine virus A. Total RNA was extracted from symptomatic leaf samples and subjected to cDNA synthesis using random hexamer primers. Then, a DNA fragment around 800 bp including the complete coat protein (CP) gene was amplified from nine out of 57 samples by polymerase chain reaction (PCR) using specific ...

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...

Red wines produced in the Xinjiang region of China possess poor color density, and lack fruity notes and elegance. The freeze concentration technique, as a well-established concentration method for liquid food systems, was applied to the Cabernet Sauvignon (Vitis vinifera L.) wine-making process, aiming to investigate its effect on wine quality improvement. Results showed that the freeze concen...

The role of Grapevine Pinot gris virus (GPGV) in the etiology of grapevine leaf mottling and deformation was investigated by biological and molecular assays. A survey on different cultivars from the Trentino Region in Italy showed a widespread distribution of GPGV, which was associated with symptomatic (79%) but also with symptomless (21%) vines. Symptomatic and GPGV-infected 'Pinot gris' vines...
