The expression of the genes positively regulated by the extracytoplasmic signaling systems in WT-RS218 and Δprc-RS218. The transcriptional levels of the genes in the σE (yiiS, hpf, and fkpA), RcsCDB (yjbE and osmC), CpxA-CpxR (aroG and mviM), QseB-QseC (qseB), and EnvZ-OmpR (ompC) regulons [22, 49,50,51,52,53,54,55] were determined by RT-PCR and visualized on agarose gels after EtBr staining. ftsZ served as a housekeeping gene internal control
