Abstract:
The complete genomic nucleotide sequence of hemisteptia virus A (HemVA) from a Hemisteptia lyrata Bunge plant in South Korea was identified by high-throughput sequencing. The HemVA genome consists of 6,122 nucleotides and contains seven putative open reading frames, ORF0-5 and ORF3a, encoding the putative proteins P0-P5 and P3a, respectively. Pairwise amino acid sequence analysis shows that the HemVA P1-P5 proteins have the highest sequence identity (23.68%-54.15%) to the corresponding proteins of members of the families Solemoviridae and Tombusviridae. Phylogenetic analysis of the P1-P2 and P3 amino acid sequences indicated that HemVA should be classified as a member of a distinct species in the genus Polerovirus.
