MICROBIOLOGY AND EVOLUTION:
Modulating Mutation Rates in the Wild

Susan M. Rosenberg and P. J. Hastings

What happens to wild isolates of Escherichia coli bacteria from all walks of life when you put them in a laboratory and starve them? In their Perspective, Rosenberg and Hastings discuss just such a scenario and explain the increased rate of stress-induced mutagenesis--a strategy that may hasten evolution--in starved, aging bacterial colonies derived from wild isolates (Bjedov et al.).
