Figure 3.

A Neighbor-joining phylogenetic tree inferred from the 16S rRNA gene sequence illustrating the diversity of myxobacteria in the Nannocystineae suborder from various salt-containing environments. Cultivated halotolerant or halophilic myxobacteria and their corresponding representative type strains are shown in bold-face. GenBank accession number is indicated in parenthesis. The sample source is shown after the accession number. The bar represents 20 nucleotide substitutions per 1000 sites. Bootstrap values are shown in the nodes based on 1000 replications. The sequence of Desulfovibrio desulfuricans strain MB was used as an outgroup to root the tree.
