摘要：
The complete genome sequence of a putative novel potyvirus, tentatively named "Polygonatum kingianum virus 1" (PKgV1), infectingPolygonatum kingianumin China was determined (GenBank accession no. MK427056). PKgV1 has a genome organization that is typical of potyviruses, with a single large open reading frame (nt 123-9236) that encodes a 3037-aa polyprotein that is predicted to be cleaved into 10 mature proteins by virus-encoded proteases. Nine cleavage sites and several conserved motifs were identified in PKgV1 by comparative sequence analysis. Pairwise comparisons revealed that the PKgV1 polyprotein shares 52.0-56.2% nucleotide and 49.2-52.8% amino acid sequence identity with members of the genusPotyvirus. Phylogenetic analysis indicated that PKgV1 clustered with members of the genusPotyvirusand that it is closely related to but distinct from lettuce mosaic virus (LMV, accession no. KJ161186). These results suggest that Polygonatum kingianum virus 1 (PKgV1) is a new member of the genusPotyvirusof the familyPotyviridae.
