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.
Pathogenicity islands—mobile genetic elements that contribute to rapid changes in …

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 …

Bacterial genomes are extremely dynamic and mosaic in nature. A substantial amount of
genetic information is inserted into or deleted from such genomes through the process of …

Bacterial genomes contain clusters of genes that are acquired by horizontal transfer, called
genomic islands (GIs). GIs are frequently associated with microbial adaptations that are of …

The compositions of bacterial genomes can be changed rapidly and dramatically through a
variety of processes including horizontal gene transfer. This form of change is key to …

Horizontal gene transfer (also called lateral gene transfer) is a major mechanism for
microbial genome evolution, enabling rapid adaptation and survival in specific niches …

Pathogenicity islands represent distinct genetic elements encoding virulence factors of
pathogenic bacteria. Pathogenicity islands belong to the class of genomic islands, which are …

Horizontal gene transfer (HGT) is arguably the most conspicuous feature of bacterial
evolution. Evidence for HGT is found in most bacterial genomes. Although HGT can …
