A putative new ampelovirus associated with grapevine leafroll disease

Arch Virol. 2010 Nov;155(11):1871-6. doi: 10.1007/s00705-010-0773-2. Epub 2010 Aug 12.


A putative new ampelovirus was detected in Vitis vinifera cv. Carnelian showing mild leafroll symptoms and molecularly characterized. The complete genome consisted of 13,625 nt and had a structure similar to that of members of subgroup I in the genus Ampelovirus (fam. Closteroviridae). In-depth analyses showed that the virus from cv. Carnelian is the most distinct member of the "GLRaV-4 lineage" of ampeloviruses, which comprises GLRaV-4, -5, -6, -9, and the recently characterized GLRaV-Pr, and GLRaV-De. This virus appears to be a new member of the family Closteroviridae, for which the provisional name grapevine leafroll-associated Carnelian virus is proposed.
