Grapevine leafroll-associated virus 1 (GLRaV-1)

The virus is one of a series of viruses associated with the grapevine leafroll disease, a widespread, graft-transmitted disease which affects grape yield and quality. This virus can be transmitted by the scale insects Neopulvinaria innumerabilis and Parthenolecanium corni. Symptoms are often dependent on the grapevine cultivar and the rootstock.

GLRaV-1 has a genome with a size of about 19 kb and 10 putative open reading frames. These encode 2 replication-associated proteins, the code protein, a transmembrane protein and others.
