Abstract excerpt
The stationary-phase response mediated by the RpoS sigma factor (σ(S), σ³⁸) has been widely studied as a general mechanism of activation of highly diverse genes that maintain cell viability. In bacteria, genes for diverse functions have been associated with this response, showing that bacteria use a large number of functions to contend with adverse conditions in their environment. However, little is known about...
