Expression of sigU and sigT. β-galactosidase activity assays of wild type and cspC strains carrying either a sigU (a) or sigT (b) transcriptional fusion to lacZ was measured at exponential-phase and 24 h growth. The results are the average of three independent assays; bars represent the standard error. Significance was assessed using 1-way ANOVA and Tukey post-test; p < 0.01 (**)
