The amino acid sequences of the virion proteins of 7 definitive tobamoviruses have been compared. The results show that the proteins may be arranged unequivocally in a single dendrogram which, by analogy with similar comparisons of other sets of homologous proteins, probably reflects their phylogeny. The magnitude of the differences between these sequences suggests that the tobamoviruses are at least as old as flowering plants. The sequence differences are significantly correlated with serological differences and with differences in amino acid composition, and so the latter was used to compute a classification of 13 tobamoviruses that also probably reflects their phylogeny. The possible ages of several other virus groups are discussed.
对7种确定的烟草花叶病毒属病毒的病毒粒子蛋白的氨基酸序列进行了比较。结果表明，这些蛋白可以明确地排列在一个单一的系统树中，通过与其他同源蛋白组的类似比较类推，这可能反映了它们的系统发育。这些序列之间差异的大小表明，烟草花叶病毒属病毒至少与开花植物一样古老。序列差异与血清学差异以及氨基酸组成差异显著相关，因此利用后者对13种烟草花叶病毒属病毒进行了分类，该分类可能也反映了它们的系统发育。还讨论了其他几个病毒组可能的年代。
