We report the physiological role of OhrR as an organic peroxide sensor and transcription repressor in Xanthomonas campestris pv. phaseoli. In vivo exposure of X. campestris pv. phaseoli to either tert-butyl or cumene hydroperoxides efficiently neutralized OhrR repression of expression from the OhrR-...
