Introduction Fanleaf degeneration/decline disease is one of the most severe viral disease complexes of grapevine worldwide. It is also one of the oldest known viral diseases of Vitis vinifera with descriptions of symptoms being reported in Europe as early as 1841. This disease is now known to affect grapevines in all temperate regions where Vitis vinifera and hybrid rootstocks are grown. Within...

Grapevine fanleaf virus (GFLV) is one of the main causes grapevine degeneration disease (GFDD) and present in almost all areas where cultivated. In this work, we ascertained presence spread GFLV different commercial vineyards four Sicilian provinces (Italy), its genetic structure molecular variability were studied. detail, a total 617 samples 11 autochthonous cultivars collected 20 vineyards. P...

Abstract Grapevine fanleaf disease, caused by grapevine virus (GFLV), transmitted the soil-borne nematode Xiphinema index , provokes severe symptoms and economic losses, threatening vineyards worldwide. As no effective solution exists so far to control disease in an environmentally friendly way, we investigated presence of resistance GFLV genetic resources. We discovered that Riesling variety d...

fanleaf degeneration, a disease caused by grapevine fanleaf virus (gflv), is considered as the most destructive grapevine viral disease worldwide causing severe losses in vineyards, annually. gflv is apparently believed to have originated from ancient persia and therefore, to restrict it in its further infections, a precise identification along with a monitoring of its distribution pattern is c...

Particles of fanleaf and yellow mosaic viruses are reported in the lumen of the esophagus of Xiphinerna index. Differences in cuticular morphology suggest differences in charged receptor sites which may offer an explanation for virus location and orderly arrangement.

Virus infected grapevines of the island of Vis display very different symptoms, such as fanleaf, yellow mosaic, vein banding, cane deformities etc. Virus isolates obtained from such plants were tested serologically by immunodiffusion in agar gel with antisera to twelve isometric viruses. A positive reaction was obtained only with grapevine fanleaf virus (GFV) antiserum. The precipitation bands ...

The nematode-borne Grapevine fanleaf virus, from the genus Nepovirus in the family Comoviridae, causes severe degeneration of grapevines in most vineyards worldwide. We characterized 347 isolates from transgenic and conventional grapevines from two vineyard sites in the Champagne region of France for their molecular variant composition. The population structure and genetic diversity were examin...

OBJECTIVE Grape virus diseases are a serious problem in Iran. Leaves and fruits of grape have been used for different purposes like cooking in Iran. The present investigation was carried out to study on the cytotoxic-activities of extracts of fruits and leaves of Vitis vinifera from both virus-free and virus-infected grape cultivars against breast cancer cell line (MDAMB- 231) and human embryon...
