Comparison of rpoS with double inrR deletion on eGFP expression from a single copy Pint-egfp fusion.

1)Time after culture inoculation. Time 24 h is onset of stationary phase.2)Average eGFP fluorescence (relative units) within the subpopulation of ICEclc active cells across biologically independent triplicates (for explanation, see Figure S7).3)Average subpopulation of cells (percent of total) expressing egfp from Pint determined from cumulative distribution curves among biologically independent triplicates.4)Significance of difference (P
