Regulation of flagellar biosynthesis. Heat map showing the expression of flagellar genes with corresponding genomic context. Color bar as in Figure 3. Arrows indicate ORFs and the direction of transcription. Gene names are indicated above or below the respective ORFs. ORFs without gene names represent genes annotated as hypothetical protein. Colored arrows represent flagellar genes belonging to class II (yellow), class III (orange), class IV (green) and motor switch complex (pink). Open arrows represent ORFs with unknown classification. Vertical red arrows indicate the position of putative CtrA binding sites found in the promoters of some flagella genes.
