23 In bacteria, two-component regulatory systems (TCSs) are the critical information-processing 24 pathways that link stimuli to specific adaptive responses. Signals perceived by membrane 25 sensors, which are generally histidine kinases (HKs), are transmitted by response regulators 26 (RRs) to allow cells to cope rapidly and effectively with environmental challenges. Over the 27 past few decad...
