Genomic islands are dynamic, ancient integrative elements in bacterial evolution.

Abstract excerpt

Acquisition of genomic islands plays a central part in bacterial evolution as a mechanism of diversification and adaptation. Genomic islands are non-self-mobilizing integrative and excisive elements that encode diverse functional characteristics but all contain a recombination module comprised of an integrase, associated attachment sites and, in some cases, a recombination directionality factor. Here, we discuss...
