by different genes, phylogenetic methods are powerful tools for detecting lateral gene transfer. …

… bacterial populations, yet allow for the separation of these populations upon bacterial
speciation. In … allelic exchange, horizontally transferred genes may initiate ecological barriers to …

… transduction) for acquiring genetic information in prokaryotes, what we call now horizontal
gene transfer (HGT). The role of gene transfer in the evolution of bacteria and archaea has …

… except minor species such as the second phosphofructokinase, … support for a specific role
of horizontal gene transfer in bacterial populations, Finally, this raises a more general question …

… from distantly related organisms, horizontal gene transfer often causes drastic changes in …
character of bacterial species and thereby promotes microbial diversification and speciation. …

… As the potential for global dispersal and widespread horizontal gene transfer (HGT) becomes
increasingly apparent, it is not implausible to consider all bacteria, or even all life on Earth, …

… This is a response to the observation that, in many cases, when multiple genomes of the
same named species are compared with one another we observe extensive variation in …

… to the strong evidence for lateral gene transfer between distantly related bacterial taxa, thereby
… a Tree of Life that results from bacterial evolution without considering such lateral gene …

… horizontal gene transfer was assumed to provide a selective advantage to either the host or
the gene itself, but could horizontally transferred genes … the boundaries between species are …

… Most of the understanding of the processes facilitating HGT and their frequencies of
occurrence have come from well designed laboratory studies of a few model bacterial species. …
