mqsR and mqsA gene expression under copper stress. The 11399-mqsR and 11399-WT cells were grown for 15 days in PW broth and then exposed to 0, 1, 3, or 7 mM of copper for 24 h. The transcript abundance was determined by real time RT-PCR. (A) Relative expression of mqsR and mqsA in 11399-mqsR compared to 11399-WT after treatment with different concentrations of copper. (B) Relative expression of mqsR and mqsA in 11399-WT following treatment with different concentrations of copper compared to the control without copper. (C) Relative expression of mqsR and mqsA in 11399-mqsR following treatment with different concentrations of copper compared to the control without copper. In all panels, data are shown as the mean of three independent biological replicates, and error bars indicate the standard error of the mean. Statistical significance was determined using Student's t-test (* indicates P < 0.05 and ** indicates P < 0.01).
