Second-order selection in bacterial evolution: selection acting on mutation and recombination rates in the course of adaptation

Res Microbiol. Jan-Feb 2001;152(1):11-6. doi: 10.1016/s0923-2508(00)01163-3.


The increase in genetic variability of a population can be selected during adaptation, as demonstrated by the selection of mutator alleles. The dynamics of this phenomenon, named second-order selection, can result in an improved adaptability of bacteria through regulation of all facets of mutation and recombination processes.
