从番茄中获得的印度黄瓜花叶病毒新德里株 (CMV-ND) 的基因组已完成测序，并与 I 和 II 亚组的 14 种已知 CMV 毒株的全基因组序列进行了比较，以了解其遗传多样性。序列分析表明，CMV-ND 在核苷酸水平上与台湾的 CMV 毒株具有最大的序列同一性。在所有 15 个 CMV 毒株中，编码的蛋白 2b 最保守，而外壳蛋白 (CP) 最保守。序列同一性值和系统图结果表明CMV-ND属于亚组I。根据重组检测程序结果，CMV很容易发生重组，并且CMV-ND的不同RNA组分有不同的进化。所有 15 个 CMV 毒株的重组分析均检测到 RNA2 中的最大重组断点； CP 显示重组位点最少。
The genome of Cucumber mosaic virus New Delhi strain (CMV-ND) from India, obtained from tomato, was completely sequenced and compared with full genome sequences of 14 known CMV strains from subgroups I and II, for their genetic diversity. Sequence analysis suggests CMV-ND shares maximum sequence identity at the nucleotide level with a CMV strain from Taiwan. Among all 15 strains of CMV, the encoded protein 2b is least conserved, whereas the coat protein (CP) is most conserved. Sequence identity values and phylogram results indicate that CMV-ND belongs to subgroup I. Based on the recombination detection program result, it appears that CMV is prone to recombination, and different RNA components of CMV-ND have evolved differently. Recombinational analysis of all 15 CMV strains detected maximum recombination breakpoints in RNA2; CP showed the least recombination sites.
