Evolution of Wolbachia cytoplasmic incompatibility types.
The success of obligate endosymbiotic Wolbachia infections in insects is due in part to cytoplasmic incompatibility (CI), whereby Wolbachia bacteria manipulate host reproduction to promote their invasion and persistence within insect populations. The observed diversity of CI types raises the question of what the evolutionary pathways are by which a new CI type can evolve from an ancestral type....
متن کاملRapid evolution of Wolbachia incompatibility types.
In most insects, the endosymbiont Wolbachia induces cytoplasmic incompatibility (CI), an embryonic mortality observed when infected males mate either with uninfected females or with females infected by an incompatible Wolbachia strain. Although the molecular mechanism of CI remains elusive, it is classically viewed as a modification-rescue model, in which a Wolbachia mod function disables the r...
متن کاملWolbachia Divergence and the Evolution of Cytoplasmic Incompatibility in Culex pipiens
Many insect species harbor Wolbachia bacteria that induce cytoplasmic incompatibility (CI), i.e. embryonic lethality in crosses between infected males and uninfected females, or between males and females carrying incompatible Wolbachia strains. The molecular mechanism of CI remains unknown, but the available data are best interpreted under a modification-rescue model, where a mod function disab...
متن کاملWolbachia infection and cytoplasmic incompatibility in Drosophila species.
Forty-one stocks from 30 Drosophila species were surveyed for Wolbachia infection using PCR technology. D. sechellia and two strains of D. auraria were found to be infected and were tested for the expression of cytoplasmic incompatibility, along with D. ananassae and D. melanogaster strains, which are already known to be infected. D. ananassae and D. melanogaster show levels of incompatibility ...
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...
