Bacterial genomes evolve through mutations, rearrangements or horizontal gene transfer.
Besides the core genes encoding essential metabolic functions, bacterial genomes also …

Horizontal transfer of genomic islands (GEIs), that is, chromosomal regions encoding
functions that can be advantageous for the host, plays a key role in bacterial evolution, but …

Horizontal gene transfer is an important mechanism for the evolution of microbial genomes.
