Average gene expression indices for σB-dependent genes. The histogram shows the average GEI of σB-dependent genes in 10403S (red) and the ΔsigB (blue) strains. GEIs were grouped in intervals of 0.7, i.e., the first bar represents genes with GEIs between 0 and 0.7; the second bar represents GEIs between > 0.7 and ≤ 1.4, etc. Genes with average GEI ≥ 50 were grouped together.
