Comparison of the nucleotide sequences of "structural" RNAs (ribosomal and transfer RNA) has enabled the construction of phylogenetic trees to be achieved. Data from 16S rRNA, 5S rRNA, and tRNA from a total of eight Mollicutes (excluding T. acidophilum) including representatives of the families Mycoplasmataceae, Spiroplasmataceae, and Acholeplasmataceae, show that these families share a close relationship and a common ancestor with the gram-positive eubacteria. Thermoplasma acidophilum is a member of the kingdom Archaebacteriae and has no relationship to the other Mollicutes.
对“结构”RNA(核糖体RNA和转运RNA)核苷酸序列的比较已使得构建系统发育树成为可能。来自总共8种柔膜菌纲微生物(不包括嗜酸嗜热放线菌)的16S rRNA、5S rRNA和tRNA的数据,这些柔膜菌纲微生物包括支原体科、螺旋体科和无胆甾原体科的代表,表明这些科与革兰氏阳性真细菌有着密切的关系和共同的祖先。嗜酸嗜热放线菌是古细菌界的成员,与其他柔膜菌纲微生物没有关系。
