Rhodospirillaceae represents a major family of the class alphaproteobacteria that includes an increasing number of functionally diverse taxa. The aim of this work is to evaluate the present phylogenetic diversity of the Rhodospirillaceae, which includes several metagenome-assembled genomes of uncultivated bacteria, as well as cultivated bacteria that were previously classified in different families. Various methodological approaches have been followed to discern the phylogenetic diversity of the taxa associated with the Rhodospirillaceae, which are grouped in three major sub-divisions and several other taxonomic entities that are currently confined to the genus rank. These genera include Tistrella, Elstera, Dongia and Ferrovibrio among cultivated organisms and alphaproteobacteria bacterium 41-28 among uncultivated bacteria. Overall, this study adds at least 11 genera and over 40 species to the current set of taxa belonging to the Rhodospirillaceae, a taxonomic term that clearly requires amendment. We propose to re-classify all taxa associated with the Rhodospirillaceae family under the new order, Diaforabacterales ord. nov. (from the Greek word for diversity, διάφορα). This study also uncovers the likely root of Rhodospirillaceae among recently reported metagenome-assembled genomes of uncultivated marine and groundwater bacteria.

球形螺旋藻科的当前系统发育:一项多方法研究。
红螺菌科代表了α-变形杆菌类的一个主要家族,其中包括数量越来越多的功能多样化的类群。这项工作的目的是评估红螺旋藻科目前的系统发育多样性,其中包括未经培养的细菌以及先前分类为不同家族的培养细菌的几个由基因组组装的基因组。已经采用了各种方法来辨别与红螺旋藻科相关的分类群的系统发育多样性,这些分类群分为三个主要细分领域以及目前仅限于属等级的其他几个分类学实体。这些属包括耕种生物体中的Tistrella,Elstera,Dongia和Ferrovibrio,未耕种细菌中包括α-变形杆菌41-28。全面的,这项研究在属于Rhodospirillaceae的当前分类单元中增加了至少11属和40多个物种,该分类学术语显然需要修改。我们建议根据新订单Diaforabacterales ord重新分类与Rhodospirillaceae家族相关的所有分类单元。十一月 (源自希腊文中的多样性,διάφορα)。这项研究还发现了最近报道的未经人工培育的海洋和地下水细菌的基因组组装基因组中的红螺旋藻科的可能根。
