N2 - 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. Based on symptoms on different test plant, the isolates were divided into two groups: the first groups causing blistering and malformation of leaves and the second showed mild mosaic and vein clearing in Nicotiana glutinosa. The almost complete nucleotide sequence of two isolates as a representative of severe and a mild isolates were determined. Genomes of two PVX Iranian isolates are identical to that of the most PVX isolates comprise 6435 nucleotides in length excluding 101 nucleotide in the 5′ end of the genome and shares 94.8–96.7 % identities with European and Asian, and 77–96.1 % with American isolates. Furthermore, the 3′-terminal sequences, including the coat protein coding region of other 13 Iranian isolates were determined and compared with the GenBank sequences. Phylogenetic analysis of the cp gene of 13 Iranian isolates together all those available in public databases indicated that the 13 Iranian isolates all belong to low diversity clade I.
