Horizontal genetic transfer (HGT) has played an important role in bacterial evolution at least
since the origins of the bacterial divisions, and HGT still facilitates the origins of bacterial …

Bacteria experience recombination in two ways. In the context of the Biological Species
concept, allelic exchange purges genic variability within bacterial populations as gene …

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 …

Studies in microbial evolution have focused on the origin and vertical transmission of
genetic variation within populations experiencing limited recombination. Genomic analyses …

Horizontal gene transfer (HGT) is an important evolutionary process that allows the spread
of innovations between distantly related organisms. We present evidence that prokaryotes …

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 …

Nucleotide sequence analysis, and more recently whole genome analysis, shows that
bacterial evolution has often proceeded by horizontal gene flow between different species …

Inspection of the genomes of bacterial pathogens indicates that their pathogenic potential
relies, at least in part, on the activity of different elements that have been acquired by …

In bacteria, horizontal gene transfer (HGT) is widely recognized as the mechanism
responsible for the widespread distribution of antibiotic resistance genes, gene clusters …

Bacterial adaptation is accelerated by the acquisition of novel traits through horizontal gene
transfer, but the integration of these genes affects genome organization. We found that …
