Abstract

First report of grapevine hammerhead viroid - like RNA (GHVd) in grapevine in Greece.

Abstract

In September 2017, leafroll disease-like symptoms were observed in a commercial grape cv. Syrah vineyard in the island of Crete, Greece. A symptomatic vine (Syr1) was selected and transferred to the Institute of Olive Tree, Subtropical Crops and Viticulture for virus analysis. The causal pathogen was isolated and identified as Grapevine hammerhead viroid (GHVd) based on various molecular analyses. This is thought to be the first report of GHVd in Greece and additional work is needed to elucidate its spread and impact on Greek grapes.
