Rrp1 regulates RpoS expression through BosR. (a) Detection of BosR, Pta, and Rrp2 via immunoblot analyses was performed as described for Fig. 6. (b) qRT-PCR analysis of bosR, rpoN, rpoS, and eno transcripts was performed as described for Fig. 4a. Data are expressed as expression of the rrp1^mut transcripts relative to that of the corresponding wild-type transcripts. Asterisks indicate that the differences between WT and rrp1^mut transcript levels were statistically significant at a P value of <0.01 (two-way ANOVA).
