ABSTRACT: More than sixty viruses have been reported from Vitis vinifera and related rootstock species/hybrids while very little is known about viruses infecting grape germplasm native to the American continent. A survey aimed at the identification of viruses present in native Vitis germplasm in the Southeastern U.S.A. was carried out in 2007 and 2008 exclusively targeting wild specimens. Shotgun sequencing of reverse-transcribed dsRNAs extracted from a specimen of Vitis aesttvalis collected from Great Smoky Mountains National Park revealed co-infection by two unrelated viruses. Complete sequences were generated for both viruses: i) a multipartite dsRNA virus related to Rice ragged stunt virus (gen. Oryzavirus; fam. Reoviridae) and ii) a luteovirid with similarities with Pea enation mosaic virus 1 (PEMV-1; gen. Enamovirus; fam. Luteoviridae). While the oryza-like virus was detected in only one additional specimen, enamo-like virus seems to be rather widespread in the native grapes. No members of these taxa were previously reported from grapevines. Susceptibility of cultivated species/hybrids to these viruses is yet to be examined.
