Complete genome sequence of Paris mosaic necrosis virus, a distinct member of the genus Potyvirus
The complete genomic sequence of a novel potyvirus was determined from Paris polyphylla var. yunnanensis. Its genomic RNA consists of 9,660 nucleotides (nt) excluding the 3’-terminal poly (A) tail, containing the typical open reading frame (ORF) of potyviruses and encoding a putative large polyprotein of 3030 amino acids. The virus shares 53.9-70.1% nt sequence identity and 43.9-73.2% amino acid sequence identity with other viruses classified within the genus Potyvirus. Proteolytic cleavage sites and conserved motifs of the potyviruses were identified in the polyprotein and within individual proteins. Phylogenetic analysis indicated that the virus is most closely related to members of the BCMV subgroup. The results suggest that the virus should be classified as a novel species within the genus Potyvirus, which we tentatively name “Paris mosaic necrosis virus”.
