FIG. 3.
(A) Expression of rpoS-lacZ translational fusion in the wild type (wt) and Fusr mutants as a function of growth stage. E is exponential growth, S is 1 h after the OD600 reached 0.5, and S + 2 is 3 h after the OD600 reached 0.5. Values shown are the means of the results from three independent measurements. Standard error bars (standard deviations of the means) are shown for each point. The data in panel B are the same as described for panel A, except that the transcription activity from the rpoS promoter is being measured.
