Molecular characterization and field survey of Iranian potato virus X isolates.

Six hundred and one symptomatic potato samples were collected from nine provinces in Iran. Screening by double-antibody sandwich enzyme linked immunosorbent assay using a potato virus X (PVX) together with a few potyviruses polyclonal antibodies, produced positive reactions in 4.3 % of samples against PVX.

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 %.
