Figure 2. Evolutionary relationships of AsIII-resistant bacteria (MS-AsIII) 16S rRNA sequences.

Figure 2

A total of 57 nucleotide sequences and 719 sites were analyzed. The phylogeny was reconstructed by maximum likelihoodand TIM3+I+G+F was selected as best fit model. Support values for each node were estimated using the Akaike Likelihood Ratio Test (aLRT). Only support values higher than 70% are shown. Reference sequences retrieved from the non-redundant database of the NCBI are shown in black, bacterial isolates (MS-AsIII and MS-AsV) in green. Different background colors highlight three well-supported clades: Firmicutes, Actinobacteria, and Proteobacteria. Thermodesulfobacteria was used as outgroup.
