Modeling suggests that gene circuit architecture controls phenotypic variability in a bacterial persistence network.

Abstract excerpt

BACKGROUND: Bacterial persistence is a non-inherited bet-hedging mechanism where a subpopulation of cells enters a dormant state, allowing those cells to survive environmental stress such as treatment with antibiotics. Persister cells are not mutants; they are formed by natural stochastic variation in gene expression. Understanding how regulatory architecture influences the level of phenotypic variability can...
