Mutational signatures indicative of environmental stress in bacteria.

Molecular biology and evolution - 1 Feb 2015

Maharjan Ram, Ferenci Thomas

Abstract excerpt

Evolutionary innovations are dependent on mutations. Mutation rates are increased by adverse conditions in the laboratory, but there is no evidence that stressful environments that do not directly impact on DNA leave a mutational imprint on extant genomes. Mutational spectra in the laboratory are normally determined with unstressed cells but are unavailable with stressed bacteria. To by-pass problems with...
