Expression of tnrA under the control of GlnRWT and GlnRSPA. Promoter activity (RLU/OD) of a PtnrA′-luc transcriptional fusion with the luc reporter gene is indicated: purple line, wild-type; red line, ΔglnR cells; green line, glnR::glnR-spa cells. Strains were grown in minimal medium supplemented with glutamine as the sole nitrogen source. Growth (OD600nm) was monitored every 5 min: black lines, wild type; grey lines, ΔglnR; blue lines, glnR::glnR-spa. For each strain, one representative curve, out of three independent replicates realized, is shown
