Abstract
The genome of a new potyvirus from a Lamprocapnos spectabilis plant in South Korea was sequenced by high-throughput sequencing and confirmed by Sanger sequencing. The new potyvirus was tentatively named "lamprocapnos virus A" (LaVA); its complete genome contains 9,745 nucleotides, excluding the 3'-terminal poly(A) tail. The LaVA genome structure is similar to that of members of the genus Potyvirus and contains an open reading frame encoding a large putative polyprotein of 3,120 amino acids (aa) with conserved motifs. The complete genome shared 48%-56% nucleotide sequence identity and the polyprotein shared 41%-52% aa sequence identity with those of other potyviruses. These values are below the standard thresholds for potyvirus species demarcation. Phylogenetic analysis based on polyprotein sequences showed that LaVA belongs to the genus Potyvirus. To our knowledge, this is the first report of the complete genome sequence and genome characterization of a potyvirus infecting Lamprocapnos spectabilis.
