Fraction of cells expressing hilA (on state) during growth in TB medium containing acetate or yeast extract (YE) (a). Mean expression of hilA promoter for cells in the on state (b). Expression from hilA promoter was determined using single-copy transcriptional fusions to GFP as determined using flow cytometry. Fraction of cells in the on state was determined relative to the negative control (100% in the off state), which consisted of the measured fluorescence of wild-type cells not containing the gfp gene during growth in TB medium Representative data are provided in Fig. 2. Error bars denote the standard deviation from three biological replicates
