A Novel marRAB Operon Contributes to the Rifampicin Resistance in Mycobacterium smegmatis
Figure 7
Assays for the effects of MarR on RIF resistance in M. smegmatis.
Growth curves of the wild-ype, marR-overexpressed, deletion mutant and complementation strains were determined as described in Experimental Procedures. These mycobacterial strains were grown in 7H9 broth in the absence (A) and presence of 4 µg/ml RIF (B). Representative growth curves are shown.
