Grapevineleafroll-associated virus 7

Grapevine leafroll-associated virus 7 (GLRaV-7) is an asymptomatic virus in the newly established genus, Velarivirus, in the Closteroviridae family. GLRaV-7 has been detected in grape-growing regions across the globe and may be quite widespread. The virus is only known to infect grapevine, is transmitted through infected propagation material, and, at this time, has no known insect vector. Detection of the virus is most reliable and accurate using RT-qPCR.
