Abstract
The complete genomic sequence of achyranthes virus A (AcVA), from an Achyranthes bidentata Blume plant in South Korea, was determined. The genomic RNA has 9491 nucleotides (nt), excluding the 3'-terminal poly(A) tail and contains an open reading frame typical of members of the genus Potyvirus, family Potyviridae, encoding a large putative polyprotein of 3103 amino acids (aa). Pairwise comparisons showed that the AcVA sequence shares 47.81-57.78% nt sequence identity at the complete genome level, 41.89-56.41% aa sequence identity at the polyprotein level, and 50-63.8% aa sequence identity at the coat protein level with other members of genus Potyvirus. These pairwise comparison values are below the species demarcation cutoff for the family Potyviridae. Our results therefore suggest that this virus should be regarded as a novel member of the genus Potyvirus, tentatively named "achyranthes virus A".
