| Abstract: | The complete nucleotide sequence of the genomic RNA of a Japanese isolate of Potato virus X (PVX), strain OS (PVX-OS), was determined. The PVX-OS genome is 6435 nucleotides in length, excluding the 3′ poly(A) sequence,
and encodes for five open reading frames (ORFs), similar to other reported PVX strains. Comparisons of the nucleotide sequence
of PVX-OS with those of European and South American PVX strains revealed that the PVX-OS genomic sequence showed 95-96% homology
with European strains and 77-78% with South American strains. Phylogenetic analysis of PVX-OS and other PVX strains found
that PVX-OS clusters with European strains. This is the first report on the complete nucleotide sequence of a PVX strain from
Japan.
