Blind killing of both male and female Drosophila embryos by a natural variant of the endosymbiotic bacterium Spiroplasma poulsonii

Bruno Lemaitre, Florent François Masson, Samuel Rommelaere, Juan Camilo Paredes Escobar, Mario Gonzalo Garcia Arraez

Spiroplasma poulsonii is a vertically transmitted endosymbiont of Drosophila melanogaster that causes male-killing, that is the death of infected male embryos during embryogenesis. Here, we report a natural variant of S. poulsonii that is efficiently verti ...

Common and unique strategies of male killing evolved in two distinct Drosophila symbionts

Bruno Lemaitre, Toshiyuki Harumoto

Male killing is a selfish reproductive manipulation caused by symbiotic bacteria, where male offspring of infected hosts are selectively killed. The underlying mechanisms and the process of their evolution are of great interest not only in terms of fundame ...

In and out—contribution of natural transformation to the shuffling of large genomic regions

Melanie Blokesch

Naturally competent bacteria can pull free DNA from their surroundings. This incoming DNA can serve various purposes, ranging from acting as a source of nutrients or DNA stretches for repair to the acquisition of novel genetic information. The latter proce ...

An Approximate Markov Model for the Wright-Fisher Diffusion and Its Application to Time Series Data

Jeffrey David Jensen

The joint and accurate inference of selection and demography from genetic data is considered a particularly challenging question in population genetics, since both process may lead to very similar patterns of genetic diversity. However, additional informat ...

A genome-to-genome analysis of associations between human genetic variation, HIV-1 sequence diversity, and viral control

Jacques Fellay, Paul Jack Mc Laren, Istvan Bartha

HIV-1 sequence diversity is affected by selection pressures arising from host genomic factors. Using paired human and viral data from 1071 individuals, we ran >3000 genome-wide scans, testing for associations between host DNA polymorphisms, HIV-1 sequence ...

Loss of reproductive parasitism following transfer of male-killing Wolbachia to Drosophila melanogaster and Drosophila simulans

Wolbachia manipulate insect host biology through a variety of means that result in increased production of infected females, enhancing its own transmission. A Wolbachia strain (wInn) naturally infecting Drosophila innubila induces male killing, while nativ ...
