Impact of Recombination on the Base Composition of Bacteria and Archaea.

Molecular biology and evolution - 1 Oct 2017

Bobay Louis-Marie, Ochman Howard

Abstract excerpt

The mutational process in bacteria is biased toward A and T, and most species are GC-rich relative to the mutational input to their genome. It has been proposed that the shift in base composition is an adaptive process-that natural selection operates to increase GC-contents-and there is experimental evidence that bacterial strains with GC-rich versions of genes have higher growth rates than those strains with...
