The genetic diversity of plum pox virus strain M (PPV-M) was assessed by analyzing 28 isolates collected in 8 European countries. Two genomic fragments spanning the (Cter)P3-6K1-(Nter)CI coding region as well as the full coat protein coding region were sequenced directly from PCR products. Phylogenetic analysis showed that the geographical origin of the collected isolates was clearly associated with two different PPV-M clades. Moreover, the pattern of substitutions in the CP gene shed light on the evolutionary relationships between PPV-M and the recombinant strains PPV-Rec and PPV-T.
通过分析在 8 个欧洲国家采集的 28 个分离物，评估了李痘病毒 M 株（PPV-M）的遗传多样性。直接从 PCR 产物中对跨越（Cter）P3-6K1-（Nter）CI 编码区的两个基因组片段以及完整外壳蛋白编码区进行了测序。系统发生分析表明，收集的分离物的地理来源与两个不同的 PPV-M 分支明显相关。此外，CP 基因中的替换模式阐明了 PPV-M 与重组株 PPV-Rec 和 PPV-T 之间的进化关系。
