Mobile genetic elements and genome evolution 2014

Mobile elements and mammalian genome evolution.

Mobile elements make up large portions of most eukaryotic genomes. They create genetic instability, not only through insertional mutation but also by contributing recombination substrates, both during and long after their insertion. The combination of whole-genome sequences and the development of innovative new assays to test the function of mobile elements have increased our understanding of h...

Mobile elements: drivers of genome evolution.

Mobile elements within genomes have driven genome evolution in diverse ways. Particularly in plants and mammals, retrotransposons have accumulated to constitute a large fraction of the genome and have shaped both genes and the entire genome. Although the host can often control their numbers, massive expansions of retrotransposons have been tolerated during evolution. Now mobile elements are bec...

Modelling the evolution of mobile genetic elements

Contribution of mobile genetic elements to Desulfovibrio vulgaris genome plasticity.

The genome of Desulfovibrio vulgaris strain DePue, a sulfate-reducing Deltaproteobacterium isolated from heavy metal-impacted lake sediment, was completely sequenced and compared with the type strain D. vulgaris Hildenborough. The two genomes share a high degree of relatedness and synteny, but harbour distinct prophage and signatures of past phage encounters. In addition to a highly variable ph...

Species hybridization is reviewed focusing on its role as a source of evolutionary novelties. Contrary to the view that hybrids are lineages devoid of evolutionary value, a number of case studies are given that show how hyb...
