Abstract
The complete genome sequence of yam chlorotic necrotic mosaic virus (YCNMV) was determined. It is a monopartite ssRNA 8208 nucleotides in length (excluding the poly(A) tail) and encoding a polyprotein of 2622 amino acids. Sequence analysis showed that the P1 region and some conserved motifs, such as the typical potyvirus aphid-transmission motifs DAG, PTK and KITC, are absent. Phylogenetic analysis based on the complete polyprotein sequences of YCNMV and selected members of the family Potyviridae clearly showed that this virus should be assigned to the genus Macluravirus and suggest that YCNMV is a new member of the genus Macluravirus.
