Evolutionary dynamics of a spatially structured host-parasite association: Drosophila innubila and male-killing Wolbachia.
The mode and tempo of host-parasite evolution depend on population structure and history and the strength of selection that the species exert on each other. Here we genetically and epidemiologically characterize populations of the mycophagous fly Drosophila innubila and its male-killing Wolbachia endosymbiont, with the aim of integrating the local through global nature of this association. Dros...

متن کاملExpression and modulation of embryonic male-killing in Drosophila innubila: opportunities for multilevel selection.
Organisms and the symbionts they harbor may experience opposing forces of selection. In particular, the contrasting inheritance patterns of maternally transmitted symbionts and their host's nuclear genes can engender conflict among organizational levels over the optimal host offspring sex ratio. This study uses a male-killing Wolbachia endosymbiont and its host Drosophila innubila to experiment...
متن کاملDisrupting the timing of Wolbachia-induced male-killing.
Several lineages of maternally inherited symbionts have evolved the ability to kill infected females' sons, a phenomenon known as male-killing. Male-killing varies in its timing, from early (death during embryogenesis) to late (mortality of late larval instars). Following the observation that treatment of male-killer infected adult females Hypolimnas bolina with tetracycline, a bacteriostatic a...
متن کاملWolbachia-Mediated Male Killing Is Associated with Defective Chromatin Remodeling
Male killing, induced by different bacterial taxa of maternally inherited microorganisms, resulting in highly distorted female-biased sex-ratios, is a common phenomenon among arthropods. Some strains of the endosymbiont bacteria Wolbachia have been shown to induce this phenotype in particular insect hosts. High altitude populations of Drosophila bifasciata infected with Wolbachia show selective...
