Increased expression and activity of the extracytoplasmic function sigma factors AlgU and SigX. Relative mRNA levels of algU and algD (A), sigX and cmpX (B) in P. aeruginosa H636 (white bars) and H636C (gray bars) relatively to H103. (C) Relative mRNA levels of PA1181, PA2072 and adcA in PAOSX [sigX mutant strain (Bouffartigues et al., 2012) relatively to H103]. (D) Relative mRNA levels of the SigX-dependent PA1181, PA2072 and adcA (PA4843) gene in P. aeruginosa H636 (white bars) and H636C (gray bars) relatively to H103. Each experiment was performed at least three times. Statistics were achieved by unpaired t-test. p < 0.05, ∗∗p < 0.01, ∗∗∗p < 0.001, NS, not significant.
