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

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 …

Although Bacteria and Archaea reproduce by binary fission, exchange of genes among
lineages has shaped the diversity of their populations and the diversification of their …

Many gene flow barriers associated with genetic isolation during eukaryotic species
divergence, are lacking in prokaryotes. In these organisms the processes associated with …

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 …

Accumulating prokaryotic gene and genome sequences reveal that the exchange of genetic
information through both homology-dependent recombination and horizontal (lateral) gene …

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 …

In bacteria, recombination is a rare event, not a part of the reproductive process.
Nevertheless, recombination—broadly defined to include the acquisition of genes from …

Microbiologists have long recognized that the uptake and incorporation of homologous DNA
from outside the cell is a common feature of bacteria, with important implications for their …

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