An ancient horizontal gene transfer between mosquito and the endosymbiotic bacterium Wolbachia pipientis.
The extent and biological relevance of horizontal gene transfer (HGT) in eukaryotic evolution remain highly controversial. Recent studies have demonstrated frequent and large-scale HGT from endosymbiotic bacteria to their hosts, but the great majority of these transferred genes rapidly become nonfunctional in the recipient genome. Here, we investigate an ancient HGT between a host metazoan and ...
متن کاملBacteriophage WO Can Mediate Horizontal Gene Transfer in Endosymbiotic Wolbachia Genomes
Phage-mediated horizontal gene transfer (HGT) is common in free-living bacteria, and many transferred genes can play a significant role in their new bacterial hosts. However, there are few reports concerning phage-mediated HGT in endosymbionts (obligate intracellular bacteria within animal or plant hosts), such as Wolbachia. The Wolbachia-infecting temperate phage WO can actively shift among Wo...
متن کاملInvestigating the presence of Wolbachia pipientis in various mosquito species
Wolbachia pipientis are endosymbionts that infect many insects, arachnids, and nematodes. By comparing the Wolbachia DNA sequences contained in different infected insect species, one can investigate the evolutionary history of arthropods and the modes of transmission of this reproductive parasite. We collected and extracted DNA from several mosquito species to test for the presence of Wolbachia...
متن کاملTaxonomic status of the intracellular bacterium Wolbachia pipientis.
Wolbachia pipientis is a maternally inherited, intracellular bacterium found in more than 20 % of all insects, as well as numerous other arthropods and filarial nematodes. It has been the subject of a growing number of studies in recent decades, because of the remarkable effects it has on its arthropod hosts, its potential as a tool for biological control of arthropods of agricultural and medic...
متن کاملEndosymbiotic and horizontal gene transfer in microbial eukaryotes
The evolution of microbial eukaryotes, in particular of photosynthetic lineages, is complicated by multiple instances of endosymbiotic and horizontal gene transfer (E/HGT) resulting from plastid origin(s). Our recent analysis of diatom membrane transporters provides evidence of red and/or green algal origins of 172 of the genes encoding these proteins (ca. 25% of the examined phylogenies), with...
