Bootstrap values > 80% are indicated by dots on branches. The scale bar indicates the average number of substitutions per site. Colour of leaves corresponds to major groups in Bacteria (Terrabacteria: marine blue, Gracilicutes: light blue, CPR: dark blue, Fusobacteria: grey blue) and in Archaea (Cluster I: orange and II: red). The group of gammaproteobacterial CsdA is indicated by a grey rectangle.
