Abstract

A novel virus, with characteristics of viruses classified within the genus Vitivirus, was identified from a sample of Vitis vinifera cv. Chardonnay in New Zealand. The virus was detected with high throughput sequencing (small RNA and total RNA) and its sequence was confirmed by Sanger sequencing. Its genome is 7507 nt long (excluding the polyA tail) with an organisation similar to that described for other classifiable members of the genus Vitivirus. The closest relative of the virus is grapevine virus E (GVE) with 65% aa identity in ORF1 (65% nt identity) and 63% aa identity in the coat protein (66% nt identity). The relationship with GVE was confirmed with phylogenetic analysis, showing the new virus branching with GVE, Agave tequilina leaf virus and grapevine virus G (GVG). A limited survey revealed the presence of this virus in multiple plants from the same location where the newly described GVG was discovered, and in most cases both viruses were detected as co-infections. The genetic characteristics of this virus suggest it represents an isolate of a new species within the genus Vitivirus and following the current nomenclature, we propose the name “Grapevine virus I”.
