对马铃薯Y病毒科中每个完全测序物种的代表的整个ORF的优化核苷酸（nt）比对进行系统发育分析，为马铃薯Y病毒属内的几个亚组提供了强有力的支持。在来自该家族的所有187个完整序列中，在整个ORF的序列和每个基因的序列之间进行了一组完整的双向比较。大多数物种在其ORF中与其属的其他成员具有50-55%的nt同一性，但存在显著的更密切相关的物种组，并且物种划分标准为
A phylogenetic analysis of the optimised nucleotide (nt) alignment of the entire ORFs of a representative of each fully-sequenced species in the family Potyviridae provided strong support for several subgroups within the genus Potyvirus. A complete set of two-way comparisons was done between the sequences for the entire ORF and for each gene amongst all the 187 complete sequences from the family. Most species had 50-55% nt identity to other members of their genus in their ORFs but there were significant groups of more closely related species and species demarcation criteria were
