Figure 4.

Time course of (a) mprA-gfp and (b) sigE-gfp expression. M. smegmatis harboring the appropriate promoter construct was grown for different periods of time (indicated in hours (h)) and the specific promoter-driven expression of GFP was monitored by flow cytometry. With time, there is a gradual transition from the L to the H subpopulation.
