使用小亚基 rRNA 基因序列对“Alphaproteobacteria”类（包括生理上多样化的物种）进行了系统发育分析。从GenBank/EMBL/DDBJ获得“Alphaproteobacteria”类261个物种的16S rRNA基因序列，并利用最大似然分析构建系统发育树。在生成的树中，“Alphaproteobacteria”类的成员被细分为五个主要簇，并将其与伯杰系统生物学手册和 ARB 树的分类概要进行了比较。基于该系统发育树，提出了三个新科： Hyphomonadaceae fam。十一月适应细菌属 Hyphomonas、Hirschia、Maricaulis 和 Oceanicaulis、Xanthobacteraceae 家族。十一月包括黄杆菌属、固氮菌属、Ancylobacter属、Labrys属和Starkeya属，以及红杆菌科家族。十一月适应红杆菌属、卟啉杆菌属和红微菌属。本研究建立的 16S rRNA 基因序列的系统发育树可能为未来“Alphaproteobacteria”类的分类学重建提供良好的基础。
Phylogenetic analysis of the class 'Alphaproteobacteria', including physiologically diverse species, was conducted by using small-subunit rRNA gene sequences. The 16S rRNA gene sequences of 261 species in the class 'Alphaproteobacteria' were obtained from GenBank/EMBL/DDBJ for constructing a phylogenetic tree by using maximum-likelihood analysis. In the resulting tree, members of the class 'Alphaproteobacteria' were subdivided into five major clusters, which were compared with the taxonomic outline of Bergey's Manual of Systematic Biology and the ARB tree. Based on this phylogenetic tree, three novel families are proposed: Hyphomonadaceae fam. nov. to accommodate the bacterial genera Hyphomonas, Hirschia, Maricaulis and Oceanicaulis, Xanthobacteraceae fam. nov. to include the genera Xanthobacter, Azorhizobium, Ancylobacter, Labrys and Starkeya, and Erythrobacteraceae fam. nov. to accommodate the genera Erythrobacter, Porphyrobacter and Erythromicrobium. The phylogenetic tree of 16S rRNA gene sequences established in this study may provide a sound basis for future taxonomic reconstruction of the class 'Alphaproteobacteria'.
