Abstract

The genera (family '') and (family ) are close relatives within the phylum . Members of these genera are strictly anaerobic, non-spore-forming and short straight rods with diverse phenotypes. Phylogenetic analysis of 16S rRNA genes suggest that splits into a polyphyletic clade. In an effort to ensure that family/genus names represent monophyletic clades, we performed a whole-genome based analysis of the genomes available for the cultured representatives of these genera: four species of and two strains of . A concatenated alignment of 135 shared protein sequences of single-copy core genes present in the included strains indicates that is indeed nested within the clade. Based on their evolutionary relationship, we propose the transfer of to the genus as comb. nov.

摘要

属（科）和属（科）是门内的近亲。这些属的成员是严格的厌氧、非孢子形成和短直杆，具有不同的表型。16S rRNA 基因的系统发育分析表明，分裂成一个多系群。为了确保科/属的名称代表单系群，我们对这些属的培养代表的基因组进行了全基因组分析：属的四个种和属的两个菌株。包含菌株中存在的 135 个单拷贝核心基因的共享蛋白质序列的串联比对表明，确实嵌套在 属的进化关系中，我们建议将 转移到属中作为 comb. nov.
