Figure 1

Genome abbreviations are given in the second column. The conventional taxonomic tree of α-proteobacteria shown on the left of the table was adapted from the NCBI Taxonomy Homepage (http://www.ncbi.nlm.nih.gov/Taxonomy/taxonomyhome.html) and is in agreement with the tree of α-proteobacteria based on 16S rRNA sequences [64]. Double plus (“++”) denotes the presence of two genes encoding copies of a given transcription factor.
