Abstract

The complete genome sequence of a putative novel potyvirus, tentatively named “polygonatum mosaic-associated virus 1” (PMaV1), was sequenced from naturally infected Polygonatum cyrtonema Hua in China. PMaV1 has a typical genome organization of potyviruses with a single large open reading frame (nt 119–9448) that encodes a 3109-aa polyprotein that is predicted to be cleaved into 10 mature proteins by virus-encoded proteases. Pairwise comparisons revealed that PMaV1 shares 71.50% complete genome sequence identity with Polygonatum kingianum virus 4 and 80.00% amino acid sequence identity with Polygonatum kingianum virus 3 of the genus Potyvirus. Phylogenetic analysis indicated that PMaV1 clustered with other potyviruses and that it was most closely related to Polygonatum kingianum virus 3 and Polygonatum kingianum virus 4. These results suggest that PMaV1 is a new member of the genus Potyvirus of the family Potyviridae (Nucleotide sequence data reported are available in the GenBank databases under the accession number OP380926).
