Fold induction of the PPA3552::lux fusion in BM2-glucose minimal medium supplemented with 2 mM Mg2+ in the presence of 6 μg/ml CP28 (A) or without peptides (B) or grown in a low (20 μM) concentration of Mg2+ (C). The results represent the averages and standard deviations of three independent assays carried out with the WT (H103), parR, UW-PA1798, and UW-PA1799 (A) strains or with the WT strain (H103), the cprR and cprS mutants, and their respective cprR+ and cprS+ complemented mutants carrying a single copy of the cprRS operon in their chromosome (B and C).
