The phylogenetic tree, based on 16S rDNA sequences, indicated that strains 117 and 43401 formed two distinct phyletic lines within the evolutionary radiation occupied by the genus Nocardia.

20株稀有放线菌的16S rDNA序列分析表明，分离菌株117、43401和12202与其相关种之间具有相对低的序列相似性，被选择以进行进一步的多相分类研究。

The phylogenetic analysis of these two nonmarine crabs together with intertidal, supratidal and swimming crabs based on portions of mitochondrial 16S rDNA sequences suggested that Grapsioidea, Ocypodoidea, Potamoidea and Portunoidea arose from a common marine ancestor, and the estimated divergence time are similar.

We have no common name for a mime of Sophron or Xenarchus and a Socratic Conversation; and we should still be without one even if the imitation in the two instances were in trimeters or elegiacs or some other kind of verse--though it is the way with people to tack on 'poet' to the name of a metre, and talk of elegiac-poets and epic-poets, thinking that they call them poets not by reason of the imitative nature of their work, but indiscriminately by reason of the metre they write in.

索夫农 、森那库斯和苏格拉底式的对话采用的模仿没有一个公共的名称；三音步诗、挽歌体或其他类型的诗的模仿也没有——人们把&诗人&这一名词和格律名称结合到一起，称之为挽歌体诗人或者史诗诗人，他们被称为诗人，似乎只是因为遵守格律写作，而非他们作品的模仿本质。
