Fluorescence intensities for cells expressing GFP from different σ54-dependent promoters. a, b Fluorescence intensities for cells in the exponential phase and the stationary phase, respectively. c Sequence alignment of the selected promoters. The − 12 and − 24 elements are boxed. Nucleotides in red represent the consensus sequence of the σ54-dependent promoters. Nucleotides that differ from the consensus sequence are shaded. Values and error bars represent the mean and the s.d. (n = 3)
