Figure 3

Identification of SigB-dependent genes by DNA microarray hybridization. Ratio/intensity (m/a) plots of DNA microarray hybridizations of sigB-proficient C. glutamicum RES167 (A) and sigB-deficient C. glutamicum CL1 (B) comparing genome-wide transcription at transition phase with that at early exponential phase. Diamonds represent genes with enhanced mRNA levels during transition phase; triangles represent genes with decreased mRNA levels. Each data point was calculated as the average of two biological and two technical replicates including dye-swapping. Selected genes, which were discussed in the text, are indicated (C) The diagram shows the numbers of genes with enhanced and reduced expression during transition phase in the sigB-proficient strain C. glutamicum RES167 (left), the sigB-deficient strain C. glutamicum CL1 (right) and in both strains (middle).
