There is a growing awareness that horizontal gene transfer (HGT) is a highly significant
phenomenon amongst single-celled organisms. The evolution of bacteria and archaea most …

Transpositional DNA rearrangements importantly contribute to the genomic plasticity of
bacteria, their viruses and plasmids. Interestingly, enzymatically mediated transposition is …

In phylogenetic reconstruction, two types of bacterial tyrosyl-tRNA synthetases (TyrRS) form
distinct clades with many bacterial phyla represented in both clades. Very few taxa possess …

Background Although originally thought to evolve clonally, studies have revealed that most
bacteria exchange DNA. However, it remains unclear to what extent gene flow shapes the …

Horizontal gene transfer (HGT), the acquisition of genetic material from non-parental
lineages, is known to be important in bacterial evolution,. In particular, HGT provides rapid …

Recombination enhances the adaptive potential of organisms by allowing genetic variants to
be tested on multiple genomic backgrounds. Its distribution in the genome can provide …

Horizontal gene transfer (HGT) spreads genetic diversity by moving genes across species
boundaries. By rapidly introducing newly evolved genes into existing genomes, HGT …

Horizontal gene transfer (HGT) confers the rapid acquisition of novel traits and is pervasive
throughout microbial evolution. Despite the central role of HGT, the evolutionary forces that …

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 …

Horizontal gene transfer (HGT) is a major contributor to bacterial genome evolution,
generating phenotypic diversity, driving the expansion of protein families, and facilitating the …
