Complete genome sequences of two Yellow oatgrass mosaic virus (YOgMV) isolates have been determined to be 9,292 nucleotides excluding the 3′ polyadenylated tail. The viral RNA encodes a large putative open reading frame (ORF) of a single polyprotein consisting of 3,002 amino acids with typical genome organization of monopartite potyvirids. A small overlapping ORF encoding a pretty interesting Potyviridae ORF of 122 amino acids is found in the P3 cistron of both YOgMV isolates. The nucleotide and amino acid identities between the two YOgMV isolates are 90 and 97 %, respectively. Pairwise comparison of YOgMV putative mature proteins and proteinase cleavage sites with those of representative members of the family Potyviridae indicated that YOgMV is more closely related to members of the genus Tritimovirus. In phylogenetic trees constructed with sequences of putative polyprotein, YOgMV consistently groups with members of the genus Tritimovirus. These results suggest that YOgMV should be classified as a distinct species in the genus Tritimovirus in the family Potyviridae.
