First report of grapevine rupestris vein feathering virus in grapevine in Germany.

Abstract

Grapevine rupestris vein feathering virus (GRVFV) is a tentative member of the genus Marafivirus in the family Tymoviridae. It was described for the first time on a Greek grapevine (Vitis rupestris) with symptoms of chlorotic discolorations of leaf veins. Since then, the virus has also been reported in the USA, Canada, Uruguay, Italy, Spain, Czech Republic, China, and most recently Switzerland, New Zealand, and Korea. In September 2017, a grapevine sample from cultivar Syrah from a vineyard from the Rhineland-Palatinate area in Germany was analysed by high-throughput sequencing. Results revealed the presence of GRVFV, Grapevine rupestris stem pitting associated virus, Grapevine yellow speckle viroid 1, and Hop stunt viroid. The presence of GRVFV in the German vineyards was confirmed by reverse transcription polymerase chain reaction and sequencing of PCR products. This is thought to be the first report of GRVFV in Germany.
