摘要
During screening of non-cultivated (wild) grapevine (Vitis sp.) from Napa County, California for the grapevine red blotch virus (GRBV; genus Glabrovirus, family Geminiviridae), an atypical polymerase chain reaction product pattern was observed. Rolling circle amplification followed by cloning and sequencing revealed the presence of a circular DNA characteristic of geminiviruses. The complete genome of nine isolates of the virus ranged from 3204 to 3278 nt in size. The genome most closely resembled that of GRBV in both sequence (57 to 59% identity) and organization. With limited sequence identity to described geminiviruses, this virus warrants designation as a new species, and the name 'Wild Vitis virus 1' is proposed.
