First report of Grapevine pinot gris virus in France

Grapevine Pinot gris virus (Trichovirus, GPGV) is a newly described virus which was originally identified in a grapevine plant (Vitis vinifera cv. ‘Pinot gris’) showing symptoms of chlorotic mottling and leaf deformations in the Autonomous Province of Trento, in Italy. The virus was then detected in the Republic of Korea, as well as in other European countries (Czech Republic, Slovakia and Slovenia - see EPPO RS 2014/006 and 2014/208). However, the pathogenicity of GPGV remains to be clarified, as it is not consistently associated with symptomatic plants. In 2014, GPGV was detected (molecular tests) for the first time in France. It was found in a leaf sample collected from a plant (Vitis vinifera cv. ‘Merlot’ grafted onto Gravesac rootstock) growing in a vineyard of the Bordeaux region. Additional RT-PCR tests detected GPGV in 2 symptomatic grapevine plants (cv. ‘Carignan) originating from a French grapevine collection. It is concluded that large-scale studies are needed to determine the world distribution of GPGV, to evaluate its potential impact on yield and wine quality, as well as to better understand its epidemiology.
