DksA_Vc modulates HAP production in V. cholerae. (A) Kinetics of HAP production in various V. cholerae strains derived from the parental strain C6709. Error bars indicate standard deviations. Strains used are as follows: Wt, C6709; ΔdksA, C-DksA1; ΔdksA+pEmpty, C-DksA1(pBR322); ΔdksA+pDksAvc, C-DksA1(pDksA_Vc). (B) Quantitative measurement of hapA transcript of V. cholerae. Relative expression of hapA in the ΔdksA strain (C-DksA1) with respect to that in the Wt (C6709) was measured by qRT-PCR. Error bars indicate standard deviations. Significant differences (**, P < 0.01) in expression are indicated from multiple comparison of each mutant versus the Wt.
