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.
确定了山药褪绿坏死花叶病毒（YCNMV）的全基因组序列。它是一个单分体ssRNA，长度为8208个核苷酸（不包括poly(A)尾），编码一个由2622个氨基酸组成的多聚蛋白。序列分析表明，P1区域以及一些保守基序，如典型的马铃薯Y病毒属蚜虫传播基序DAG、PTK和KITC不存在。基于YCNMV完整多聚蛋白序列和马铃薯Y病毒科选定成员的系统发育分析清楚地表明，该病毒应归入甘薯潜隐病毒属，并表明YCNMV是甘薯潜隐病毒属的一个新成员。
