FIG 2.

Expression of yaiC and fimA under phosphate-limiting conditions. (A) Expression of yaiC in strains grown in LB compared to WT strain. (B) Expression of yaiC in strains grown under low-phosphate (LP) conditions. Expression in LP broth was compared to expression of the corresponding strains grown under high-phosphate (HP) conditions. (C) Expression of fimA in strains grown in LP broth. The expression was compared with those of the WT strain grown in LP broth. The dotted lines correspond to the cutoff of a significant difference in expression. All results shown are the mean values and standard deviations of the results from four biological experiments. Statistical significance was calculated by the Student t test; *, P < 0.05; **, P < 0.005; ***, P < 0.0001; NS, nonsignificant.
