Abstract
We herein present the complete genome sequence of codonopsis torradovirus A (CoTVA), which was isolated from Codonopsis lanceolata (deodeok) in Gangwon-do, South Korea. The CoTVA genome contains two positive-sense RNA segments, namely RNA1 (6922 nucleotides), which encodes a predicted polyprotein, and RNA2 (4613 nucleotides), which encodes a movement protein and coat proteins (CPs). The proteinase-polymerase (Pro-Pol) and CP amino acid sequences were 75% and 54% identical, respectively, to those of motherwort yellow mosaic virus. Pairwise comparisons of the Pro-Pol and CP sequences revealed that the virus described in this study should be considered a member of a new torradovirus species. Phylogenetic analysis of the Pro-Pol sequence encoded by RNA1 and the CP region encoded by RNA2 indicated that CoTVA is a new member of the genus Torradovirus in the family Secoviridae. CoTVA is the first torradovirus detected in Codonopsis lanceolata.
