Delineation of the Rv1057 promoter using lacZ reporter constructs. (A) Dashed lines indicate the sections of the Rv1056-Rv1057 intergenic region inserted upstream of lacZ in constructs P1-P3. P4 represents the promoterless lacZ control pSM128. (B) H37Rv and Rv-D981 were transformed with constructs P1-P4. Recombinants strains were exposed to 0.05% SDS for 90 min or left unexposed (controls). RNA was extracted, and lacZ expression was evaluated by qRT-PCR. Data are the mean +/− SEM from triplicate experiments.
