Horizontal gene transfers as metagenomic gene duplications.
While it is well accepted that horizontal gene transfer plays an important role in the evolution and the diversification of prokaryotic genomes, many questions remain open regarding its functional mechanisms of action and its interplay with the extant genome. This study addresses the relationship between proteome innovation by horizontal gene transfer and genome content in Proteobacteria. We ch...
متن کاملHorizontal gene transfers in vicious parasites
Microsporidia are obligate intracellular parasites whose genomes have been shaped by an extreme lifestyle. Specifically, their obligate intracellular parasitism has resulted in the loss of many genes and biochemical pathways, but these reductive processes have been often offset by the acquisition of several genes by means of horizontal gene transfer (HGT). Until recently, these HGTs were all fo...
متن کاملDetection of Horizontal Gene Transfers from Phylogenetic Comparisons
Bacterial phylogenies have become one of the most important challenges for microbial ecology. This field started in the mid-1970s with the aim of using the sequence of the small subunit ribosomal RNA (16S) tool to infer bacterial phylogenies. Phylogenetic hypotheses based on other sequences usually give conflicting topologies that reveal different evolutionary histories, which in some cases may...
متن کاملPrediction of horizontal gene transfers in eukaryotes: approaches and challenges.
HGT (horizontal gene transfer) is recognized as an important force in bacterial evolution. Now that many eukaryotic genomes have been sequenced, it has become possible to carry out studies of HGT in eukaryotes. The present review compares the different approaches that exist for identifying HGT genes and assess them in the context of studying eukaryotic evolution. The metabolic evolution resourc...
متن کاملAdaptive Horizontal Gene Transfers between Multiple Cheese-Associated Fungi
Domestication is an excellent model for studies of adaptation because it involves recent and strong selection on a few, identified traits [1-5]. Few studies have focused on the domestication of fungi, with notable exceptions [6-11], despite their importance to bioindustry [12] and to a general understanding of adaptation in eukaryotes [5]. Penicillium fungi are ubiquitous molds among which two ...
