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

Horizontal gene transfer is the collective name for processes that permit the exchange of
DNA among organisms of different species. Only recently has it been recognized as a …

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

To what extent is the tree of life the best representation of the evolutionary history of
microorganisms? Recent work has shown that, among sets of prokaryotic genomes in which …

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 …

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

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 …

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

Bacterial and archaeal evolution involve extensive gene gain and loss. Thus, phylogenetic
trees of prokaryotes can be constructed both by traditional sequence-based methods (gene …

The importance of lateral gene transfer in genome evolution of microbial eukaryotes is
slowly being appreciated. Acquisitions of genes have led to metabolic adaptation in diverse …
