Fig. 7: The SiPc-dependent induction of Pspy is reduced in cpxR mutants and not detectable in baeR mutants.

Shown is the YFP/CFP expression in response to SiPc after photoactivation in wild-type and cpxR mutant (A) and wild-type and baeR mutant (C), as well as the respective controls (B, D). The response of the Pspy module to SiPc after light activation is reduced in cpxR mutants (E) and completely absent in baeR mutants when compared to wild type (compare E and 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).
