Recombination-Dependent Mutation in Escherichia coli Occurs in Stationary Phase

[摘要] “ADAPTIVE” or “stationary-phase” mutation occurs in apparently stationary-phase populations of cells, over time, after exposure to a nonlethal selection. In one assay system, Escherichia coli with an amber mutation in lacZ forms Lac+ colonies over time when plated on medium with lactose as
