10 lis 2022 · We identified which of these bacterial species are truly clonal, classified bacteria into biological species by redefining species boundaries based on gene flow, and analyzed the patterns of gene flow between species (i.e., introgression).
27 sty 2024 · A global survey of prokaryotic genomes reveals the eco-evolutionary pressures driving horizontal gene transfer. Quantifying the local adaptive landscape of a nascent bacterial community....
15 maj 2017 · The major mechanisms of DNA transfer in bacteria — natural transformation, transduction and conjugation — have been described in detail (Box 2). Although mechanistic insights in archaea are ...
26 wrz 2016 · In this minireview, we first compare two general evolutionary trajectories for the way in which small molecules originate and spread, and then we review recent observations that illustrate how HGT contributes to the catalogue of small molecules within specialized bacterial niches.
12 lis 2021 · Horizontal gene transfer (HGT) is arguably the most conspicuous feature of bacterial evolution. Evidence for HGT is found in most bacterial genomes.
Genetic exchange plays a defining role in the evolution of many bacteria. The recent accumulation of nucleotide sequence data from multiple members of diverse bacterial genera has facilitated comparative studies that have revealed many features of this process.
The small proportion of shared genes among closely related bacteria suggests that horizontal gene transfer is not only a potent force leading to the acquisition of new genes and new functions but in addition, it must be a rapid process.
