Abstract

The complete 9,556-nt genomic sequence of a putative new potyvirus, tentatively named “platycodon mild mottle virus” (PlaMMV), infecting Platycodon grandiflorum was determined (GenBank accession no. MH779625). A single large open reading frame (ORF; nt 121-9360, 3079 aa) encoding a polyprotein that was predicted to be cleaved into 10 mature proteins was detected. By comparison with other potyviruses, nine cleavage sites and conserved domains/motifs were identified. PlaMMV also has a highly conserved GA 6 motif (nt 2857-2863) that could enable a small overlapping ORF (PIPO) embedded within the P3 cistron to be translated by a viral polymerase slippage mechanism. A BLAST analysis showed that the complete PlaMMV nucleotide sequence shared 70% identity (40% query coverage) with carrot thin leaf virus (JX156434) and that the complete amino acid sequence of the PlaMMV polyprotein shared 54% identity (98% query coverage) with Thunberg fritillary mosaic virus (CAI59123). These results suggest that PlaMMV is a new member of the genus Potyvirus in the family Potyviridae.
