Evolution of the RpoS Regulon: Origin of RpoS and the Conservation of RpoS-Dependent Regulation in Bacteria
Abstract
The RpoS sigma factor in proteobacteria regulates genes in stationary phase and in response to stress. Although of conserved function, the RpoS regulon may have different gene composition across species due to high genomic diversity and to known environmental conditions that select for RpoS mutants. In this study, the distribution of RpoS homologs in prokaryotes and the differential dependence of regulon members on RpoS for expression in two …
