Abstract
Contigs with sequence similarity to potato virus P (PVP), which belongs to the genus Carlavirus, were identified by high-throughput sequencing analysis in potato tubers collected from a farmer's potato production field in Surazhevka, Artyom, Primorskiy Krai (Russia) in 2018. The complete genome sequence of this virus consisted of 8,394 nucleotides, excluding the poly(A) tail. This is the first report of PVP being detected outside South America. The isolate had high sequence similarity to PVP isolates from Argentina and Brazil, but low sequence similarity was observed in the genes encoding the RNA-dependent RNA polymerase (69% nucleotide sequence identity and 80% amino acid sequence identity) and coat protein (78% nucleotide sequence identity and 89% amino acid sequence identity). Phylogenetic analysis revealed that this PVP-like virus clustered with known PVP isolates but was distinct from them. Comparison of the sequences using the classification criteria of the ICTV indicated that this PVP-like virus is a strain of PVP.
