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....
7 maj 2021 · Here, we model the evolution of 11,272 gene families to identify the root, extent of horizontal gene transfer (HGT), and the nature of the last bacterial common ancestor (LBCA). Our analyses root the tree between the major clades Terrabacteria and Gracilicutes and suggest that LBCA was a free-living flagellated, rod-shaped double-membraned ...
6 kwi 2012 · Bacterial speciation is driven by interplay between natural selection, genetic linkage, and lateral gene transfer. Most people today recognize bacterial names like Escherichia coli and Neisseria meningitidis. Yet, from an evolutionary viewpoint, the clarity of species labels for bacteria is blurred by rampant horizontal gene transfer between ...
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.
1 mar 2013 · Here we synthesize recent literature demonstrating the importance of habitat and niche in structuring horizontal gene transfer. This leads to a model of ecological speciation via gradual genetic isolation triggered by differential habitat-association of nascent populations.
10 lis 2022 · Results Here, we analyze the patterns of gene flow within and between >2600 bacterial species. Our results show that fewer than 10% of bacterial species are truly clonal, indicating that...
