The complete nucleotide sequence of peach virus D (PeVD) from Prunus persica was determined. The PeVD genome consists of 6,612 nucleotides excluding the 3' poly(A) tail and contains a single open reading frame coding for a polyprotein of 227 kDa. Sequence comparisons and phylogenetic analysis revealed that PeVD is most closely related to viruses in the genus Marafivirus, family Tymoviridae. The complete nucleotide and CP amino acid sequences of PeVD were most similar (51.1-57.8% and 32.2-48.0%, respectively) to members of the genus Marafivirus, suggesting that PeVD is a new member of this genus.
测定了来自桃（Prunus persica）的桃病毒D（PeVD）的完整核苷酸序列。PeVD基因组由6612个核苷酸组成（不包括3' 多聚腺苷酸尾），包含一个单一的开放阅读框，编码一个227 kDa的多聚蛋白。序列比较和系统发育分析表明，PeVD与番茄丛矮病毒科马拉病毒属中的病毒关系最为密切。PeVD的完整核苷酸序列和外壳蛋白氨基酸序列与马拉病毒属成员最为相似（分别为51.1 - 57.8%和32.2 - 48.0%），这表明PeVD是该属的一个新成员。
