Comparative analysis of the HrpB/X regulon. a Experimental HrpB and HrpX motifs used in the analysis, with number of available binding sites indicated. b Weighted mixture motifs generated by CGB on different target species following the HrpB/X-based phylogenetic tree. c Partial view of the CGB-generated heatmap depicting the HrpB/X regulon across 37 complete bacterial genomes encompassing members of the Comamonadaceae, Burkholderiaceae, Oxalobacteraceae and Xanthomonadaceae families. Each row represents an orthologous group, sorted by average posterior probability of regulation. Cells are colored from green (regulation) to red (no regulation); blue denotes ortholog absence. Colored circles next to species names indicate propagated motif (panel B) used in the genome search for the species. d Bootstrapped ancestral state reconstruction of the posterior probability of regulation for virulence regulator PhrI
