Values (relative to wild-type levels) are averages and standard deviations of the results from three independent biological replicates. All genes listed had a Cyber-T Bayesian P value of <0.001 (see Materials and Methods for experimental details).
TCS, two-component system that includes histidine kinase and response regulator.
Positive polar effect was indicated by strong expression of upstream genes.
