The 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...

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 کاملAutomating the Search for Lateral Gene Transfer
Most genes have attained their observed distribution among genomes by transmission from parent to offspring through time. In prokaryotes (bacteria and archaea), however, some genes are where they are as the result of transfer from an unrelated lineage. To elucidate the biological origins and functional consequences of lateral gene transfer (LGT), we have constructed an automated computational p...
