Stationary phase mutagenesis: mechanisms that accelerate adaptation of microbial populations under environmental stress.

Abstract

Microorganisms are exposed to constantly changing environmental conditions. In a growth-restricting environment (e.g. during starvation), mutants arise that are able to take over the population by a process known as stationary phase mutation. Genetic adaptation of a microbial population under environmental stress involves mechanisms that lead to an elevated… (More)
