Genome sequence of a divergent Colombian isolate of potato virus V (PVV) infecting Solanum phureja.

ABSTRACT

Deep sequencing analysis of the transcriptome of a Solanum phureja cv. Criolla Colombia plant with symptoms typical of a virus disease revealed an infection with potato virus V (PVV). The PVV-phureja genome comprises 9904 nt, exhibits 83% nucleotide identity with currently fully sequenced PVV isolates and contains one large ORF that codes for a polyprotein of 3065 residues flanked by 5' and 3' UTR of 217 and 448 nt, respectively. Phylogenetic analysis of the PVV-phureja polyprotein indicates that it is divergent with respect to most PVV isolates. This is the first complete PVV genome of an isolate infecting a host different to S. tuberosum and, to this date, the only one from the South American Andes.
