A. Sequences of selected promoters. The transcriptional start sites mapped previously are in bold and underlined [22, 29]. The putative -35 and -10 boxes are highlighted in grey. B. (left panel) Fold-change values from microarray experiments. (middle panel) Luciferase activity of luxCDABE transcriptional fusions to selected promoters in the wild type (WT), ecfG1 mutant (ΔecfG1), ecfG2 mutant (ΔecfG2), double ecfG1 ecfG2 mutant (Δ2), sextuple mutant (Δ6) or phyR mutant (ΔphyR). Cultures were treated with 1% ethanol (ethanol), 20 mM salt (salt) or H2O (control) in exponential phase 60 minutes prior to measurement, or were grown to stationary phase. The right panel shows the same stationary phase values with different axis ranges in order to better see the differences between the strains. AU, arbitrary units.
