Wolbachia-Mediated Cytoplasmic Incompatibility Is Associated with Impaired Histone Deposition in the Male Pronucleus
Wolbachia is a bacteria endosymbiont that rapidly infects insect populations through a mechanism known as cytoplasmic incompatibility (CI). In CI, crosses between Wolbachia-infected males and uninfected females produce severe cell cycle defects in the male pronucleus resulting in early embryonic lethality. In contrast, viable progeny are produced when both parents are infected (the Rescue cross...
متن کاملWolbachia-Induced Cytoplasmic Incompatibility Is Associated with Decreased Hira Expression in Male Drosophila
BACKGROUND Wolbachia are obligate endosymbiotic bacteria that infect numerous species of arthropods and nematodes. Wolbachia can induce several reproductive phenotypes in their insect hosts including feminization, male-killing, parthenogenesis and cytoplasmic incompatibility (CI). CI is the most common phenotype and occurs when Wolbachia-infected males mate with uninfected females resulting in ...
متن کاملDoes pupal communication influence Wolbachia-mediated cytoplasmic incompatibility?
Wolbachia are widespread endosymbiotic bacteria found in terrestrial arthropods and filarial nematodes [1]. In insects, Wolbachia generally rely on diverse strategies to manipulate their host's reproduction and favor their own vertical transmission through infected eggs [2]. One such mechanism is a sterility syndrome called 'cytoplasmic incompatibility'. Cytoplasmic incompatibility occurs at fe...
متن کاملResponse to “Does pupal communication influence Wolbachia-mediated cytoplasmic incompatibility?”
In a recent Current Biology paper [1], we reported that pheromone communication occurred during metamorphosis in Drosophila melanogaster. Female pheromones appeared to influence various aspects of the physiology and development of adult males. In particular, we observed that this communication regulated testis development and had a positive impact on reproduction, as measured by a difference in...
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...
