The complete genome sequence of a divergent grapevine virus I isolate naturally infecting grapevine in Greece.

A significant number of new members of the genus Vitivirus have been identified recently, mainly due to the advent of high-throughput sequencing (HTS). Grapevine virus I (GVI), which was identified in New Zealand in 2018, is one of these viruses. RNAseq HTS analysis of a Greek grapevine (cv. Daphnia), revealed the presence of a GVI-like isolate (D2-1/19). Sequence analysis confirmed the classification of D2-1/19 as GVI. However, both sequence and phylogenetic data exhibited high levels of variability between D2-1/19 and the previously characterized GVI isolates. This study provides the full-length sequence of a divergent GVI isolate, adding knowledge to the limited information available about this recently identified virus.
