Fig. 6: The MB-dependent induction of Pdps is not affected in mntR mutants, but absent in oxyR mutants.

Shown is the YFP/CFP expression in response to MB after photoactivation in wild-type and mntR mutant (A) and wild-type and oxyR mutant (C), as well as the respective controls (B, D). As opposed to mntR mutants, the total response of the Pdps module to MB after light activation is significantly reduced in oxyR mutants (E) and very similar to the water control (F). The dashed lines indicate the time point of the addition of the test substance. Shown are the results of representative experiments. The columns (E, F) represent the average results of three biological replicates (*P < 0.05; **P < 0.01; ***P < 0.001).
