ABSTRACT
The complete genomic sequence of scorzonera virus A (SCoVA) from a Scorzonera austriaca Willd. plant in South Korea was determined by high-throughput sequencing and confirmed by Sanger sequencing. The SCoVA genome contains 9867 nucleotides, excluding the 3'-terminal poly(A) tail. The SCoVA genome structure is typical of potyviruses and contains a single open reading frame encoding a large putative polyprotein of 3168 amino acids. Pairwise comparison analysis of the complete genome and polyprotein sequences of SCoVA with those of other potyviruses showed that they shared the highest nucleotide and amino acid sequences identity (54.47% and 49.57%, respectively) with those of lettuce mosaic virus (GenBank accession number KJ161185). Phylogenetic analysis of the amino acid sequence of the polyprotein confirmed that SCoVA belongs to the genus Potyvirus. These findings suggest that SCoVA should be considered a novel member of the genus Potyvirus, family Potyviridae.
