title: Introduction to bacterial signal transduction networks.
abstract: Transcriptional analysis using a DNA microarray is an extremely efficient method for analyzing two-component signal transduction networks. Here we introduce three such networks in Escherichia coli that were clarified using a DNA microarray: a PhoQ/PhoP system that senses extracellular Mg2+ and controls the gene expression for adaptation to environmental Mg2+ deprivation (Mg2+ stimulon); an EvgS/EvgA signal transduction system that activates expression of multiple drug efflux pumps and acid resistance genes; and a signal transduction cascade between EvgS/EvgA and PhoQ/PhoP.
