Fig. 3.

RAxML tree calculated with an alignment of 74 protein sequences extracted from 85 genome sequences. Taxa affiliated with the phylum Proteobacteria are shown by using colour codes. All proteobacterial classes (including ‘Zetaproteobacteria’) but Deltaproteobacteria are shown by colour-coded fonts. Deltaproteobacterial orders are highlighted by colour-coded areas. Furthermore, the two representatives of the phylum Acidobacteria are highlighted by red fonts. Bootstrap values obtained by the RAxML, MrBayes and Neighbour-Joining method are depicted. The coloured dots indicate nodes supported by different treeing methods.
