a The percentage of the population expressing GFP under control of PcomG (St29, St145, St158 and St177) in a wild type background or in the absence of srrA, nreC, or airR was determined after 26 hours of growth in GS medium. The results are presented as mean ± SD. For each strain, the percentage of the population expressing GFP has been calculated from at least 4 independent experiments (biological replicates). Individual experiments are shown as blue circles. b The percentage of the population expressing GFP under control of PcomG (St29, St41, St158 and St273) in a wild type background or in the absence of comK2, nreC, or both, was determined after 26 hours of growth in GS medium. The results are presented as mean ± SD. For each strain, the percentage of the population expressing GFP has been calculated from at least 5 independent experiments (biological replicates). Individual experiments are shown as blue circles. Statistical significance was evaluated by two-way ANOVA with Tukey’s posthoc test as follows: *P < 0.05.
