متن کاملLateral and oblique gene transfer.
Sequence information from complete genomes, and from multiple loci of strains within species, is transforming the way that we investigate the evolution of bacteria. Such large-scale assessments of bacterial genomes have provided evidence of extensive gene transfer and exchange. Except in rare cases, these two processes do not seem to be coupled: certain species, such as Escherichia coli, underg...
متن کاملLateral Gene Transfer from the Dead
In phylogenetic studies, the evolution of molecular sequences is assumed to have taken place along the phylogeny traced by the ancestors of extant species. In the presence of lateral gene transfer, however, this may not be the case, because the species lineage from which a gene was transferred may have gone extinct or not have been sampled. Because it is not feasible to specify or reconstruct t...
متن کاملLateral Gene Transfer, Rearrangement and Reconciliation
Background. Models of ancestral gene order reconstruction have progressively integrated different evolutionary patterns and processes such as unequal gene content, gene duplications, and implicitly sequence evolution via reconciled gene trees. In unicellular organisms, these models have so far ignored lateral gene transfer, even though it can have an important confounding effect on such models,...
متن کاملThe chemostat with lateral gene transfer.
We investigate the standard chemostat model when lateral gene transfer is taken into account. We will show that when the different genotypes have growth rate functions that are sufficiently close to a common growth rate function, and when the yields of the genotypes are sufficiently close to a common value, then the population evolves to a globally stable steady state, at which all genotypes co...
