Figure 4. Alternative sigma factor σH up-regulates the mRNA levels of prophage integrases.

Figure 4

Deletion of sigH causes a reduction of prophage integrase mRNAs. The complementation of sigH gene (ΔsigHc) by transforming pMADsigH that integrated into host genome recovered the transcriptional levels of integrases. The integrases levels are indicated as the relative mRNA levels compared with the 16S RNA control (n = 3 samples/group, *p<0.05).
