Abstract
A novel virus infecting a Paris polyphylla var. yunnanensis plant, tentatively named "Paris polyphylla chlorotic mottle virus" (PpCMV), was discovered in the city of Lijiang, Yunnan Province, China. Its genome consists of 6384 nucleotides (nt), excluding the 3′-terminal poly(A) tail, and contains two open reading frames: ORF1 and ORF2. ORF1 is 6150 nt in length, encoding a large 2050-aa polyprotein with at least two conserved regions encoding a replication-associated protein and a coat protein, the latter of which is located at the 3′ end of ORF1. ORF2, consisting of 1185 nt, is located within ORF1 but has a different reading frame. It encodes a 394-aa-long putative movement protein. Phylogenetic analysis based on amino acid sequences revealed that the newly discovered virus exhibited the closest relationship to Hobart betaflexivirus 1 and rhodiola betaflexivirus 1, both of which belong to the genus Capillovirus, sharing 48.8% and 36.5% amino acid sequence identity, respectively, in the structural protein. This is the first report of the complete genome sequence of PpCMV in China.
