Fig. 2. A neighbor-joining phylogenetic tree, based on 16S rRNA gene sequences, showing the phylogenetic relationships between the strains isolated in this study and their relatives in the orders Caulobacterales, Rhizobiales, Rhodobacterales, Rhodospirillales, and Sphingomonadales of the class of Alphaproteobacteria. Bootstrap values (>70%) are shown above nodes. Scale bar: 0.02 changes per nucleotide.
