Graphical representation of selected genes and putative operons comprising genes of classe A in their genomic organization. Below each gene, the induction or repression ratios are given for both strains, C. glutamicum RES167 and its derived Δrel mutant. Bold numbers indicate a significant induction or repression of the corresponding gene according to the filtering criteria (5% error probability) applied on the microarray data. Genes are not drawn to scale. Known transcription start points are marked by small arrows. Predicted rho-independent terminators are indicted by hairpins.
