The rpoS-encoded sigmaS subunit of RNA polymerase regulates the expression of stationary phase and stress response genes in Escherichia coli. Recent study of our DNA microarray analysis suggested that the rpoS expression is affected by multiple two-component systems. In this study, we identified two-component-system mutants in which the rpoS expression increased. The regulatory manner of the systems on rpoS expression is suggested.
