The complete coat protein nucleotide sequences of 11 Potato virus X isolates from Australia and two from Britain were compared to those of 72 others. On phylogenetic analysis, clade I contained all 11 Australian sequences, and sub-clade II-1 contained the two new British sequences. Clade I isolates were from six different continents, but those in sub-clades II-1 and II-2 were only from Europe and the Americas, respectively. Clade I contained isolates in strain groups 1, 3 and 4, and sub-clades II-1 and II-2, isolates in strain groups 2 and 4. Thus, strain group 4 now occurs within both clades.
对来自澳大利亚的 11 个马铃薯 X 病毒分离株和来自英国的 2 个病毒分离株的完整外壳蛋白核苷酸序列与其他 72 个分离株进行了比较。系统进化分析表明，I 类群包含所有 11 个澳大利亚分离株，而 II-1 亚类群包含 2 个新的英国分离株。I 类群的分离株来自六大洲，但 II-1 和 II-2 亚类群的分离株分别仅来自欧洲和美洲。I 类群包含了 1 组、3 组和 4 组以及 II-1 和 II-2 亚类群的分离株，而 II-1 和 II-2 亚类群的分离株则包含了 2 组和 4 组。因此，现在 4 组在两个类群中都有出现。
