Here, we report the complete genome sequence of a novel polerovirus, "Plantago asiatica virus A" (PlaVA), detected in Plantago asiatica using high-throughput RNA sequencing and validated by Sanger sequencing. The complete PlaVA genome contains 5,881 nucleotides and has seven open reading frames (ORF0-5 and ORF3a) encoding putative proteins (P0-5 and P3a, respectively) in an arrangement that is similar to that of typical Polerovirus members. Pairwise sequence comparisons revealed that P0 to P5 encoded by PlaVA had the highest sequence identity (25.48%-79.21%) to the corresponding proteins of previously reported poleroviruses. A phylogenetic analysis using the PlaVA P1-2 and P3 amino acid sequences and those of members of the family Solemoviridae (formerly Luteoviridae) indicated that although PlaVA belongs to the genus Polerovirus, it does not represent a known species. Consequently, PlaVA should be considered a member of a new species within the genus Polerovirus. © 2021.
