Population Genomics of the Wolbachia Endosymbiont in Drosophila melanogaster
Wolbachia are maternally inherited symbiotic bacteria, commonly found in arthropods, which are able to manipulate the reproduction of their host in order to maximise their transmission. The evolutionary history of endosymbionts like Wolbachia can be revealed by integrating information on infection status in natural populations with patterns of sequence variation in Wolbachia and host mitochondr...
متن کاملThe Gut Commensal Microbiome of Drosophila melanogaster Is Modified by the Endosymbiont Wolbachia
Endosymbiotic Wolbachia bacteria and the gut microbiome have independently been shown to affect several aspects of insect biology, including reproduction, development, life span, stem cell activity, and resistance to human pathogens, in insect vectors. This work shows that Wolbachia bacteria, which reside mainly in the fly germline, affect the microbial species present in the fly gut in a lab-r...
متن کاملThe endosymbiont Wolbachia increases insulin/IGF-like signalling in Drosophila
Insulin/IGF-like signalling (IIS) is an evolutionarily conserved pathway that has diverse functions in multi-cellular organisms. Mutations that reduce IIS can have pleiotropic effects on growth, development, metabolic homeostasis, fecundity, stress resistance and lifespan. IIS is also modified by extrinsic factors. For instance, in the fruitfly Drosophila melanogaster, both nutrition and stress...
متن کاملDraft Genome Sequence of the Wolbachia Endosymbiont of Drosophila suzukii
Wolbachia is one of the most successful and abundant symbiotic bacteria in nature, infecting more than 40% of the terrestrial arthropod species. Here we report the draft genome sequence of a novel Wolbachia strain named "wSuzi" that was retrieved from the genome sequencing of its host, the invasive pest Drosophila suzukii.
متن کاملPopulation Genomics of Inversion Polymorphisms in Drosophila melanogaster
Chromosomal inversions have been an enduring interest of population geneticists since their discovery in Drosophila melanogaster. Numerous lines of evidence suggest powerful selective pressures govern the distributions of polymorphic inversions, and these observations have spurred the development of many explanatory models. However, due to a paucity of nucleotide data, little progress has been ...
