Regulatory network of D. vulgaris Hildenborough. Circular-genome diagram depicting the loci of all RRs, the corresponding mapped genes and predicted functions based on putative annotated functions of target genes. The figure was generated using a modified Circos script . Genes and connections are as labeled in the figure. Color legends are derived from maps in Figures 4, 5 and 6. Probable functions of RRs as suggested by regulated genes are shown in green boxes. Cognate histidine kinases, where predicted, are shown in gray. Figure does not include pDV1 borne RRs or target genes that map to this plasmid. RR, response regulator; sRNA, small RNA.
