Gammaproteobacteria phylogenetic tree. Neighbor-joining trees were constructed from aligned, full-length clone 16S rRNA sequences of OTUs detected more than once, based on 1,153 homologous positions filtered by base frequency (50%) using MEGA6. Tag sequences that were identical to a clone sequence were identified. Bootstrap values were calculated in MEGA6, and nodes with >50% support, based on 1,000 replicates are displayed. Haliangium tepidum (NR_024781) and Kofleria flava (NR_041981) were used as outgroups.
