Incidence and characterization of Potato virus V infections in Iran

A survey was carried out to determine the extent of Potato virus V (PVV) infection, together with other potyviruses, in Iran in both commercial and local potato varieties. We found a low incidence of PVV in commercial varieties compared to a local potato cultivar Zardi, in which we noted a PVV infection up to ~32.9 %. We determined the genomic sequence 9,812 nucleotides of one isolate (KER.LAL.P) from cultivar Agria and the 3′-terminal sequence including coat protein (CP) gene of four additional isolates from cultivar Zardi. The Iranian isolate PVV KER.LAL.P was found to share 91 % sequence identity with the Scottish isolate DV-42 (AJ243766) of PVV. The CP gene sequences of the PVV isolates from Iran shared 96.5 to 99.3 % pairwise nucleotide identity and they shared
