Evolution: bacterial mutation in stationary phase.
A recent study indicates that the genomic mutation rate of the gut bacterium Escherichia coli is substantially higher in nongrowing than growing cultures. These findings are important in the light of the ongoing controversy over the generality and robustness of stationary phase mutagenesis and its evolutionary implications.
