The effect of Wolbachia-induced cytoplasmic incompatibility on host population size in natural and manipulated systems.
Obligate, intracellular bacteria of the genus Wolbachia often behave as reproductive parasites by manipulating host reproduction to enhance their vertical transmission. One of these reproductive manipulations, cytoplasmic incompatibility, causes a reduction in egg-hatch rate in crosses between individuals with differing infections. Applied strategies based upon cytoplasmic incompatibility have ...
متن کاملCytoplasmic incompatibility in social insects
In this essay, I briefly summarise reproductive phenotypes associated withWolbachia in insects, present a model of the dynamics of infection frequency for maternally-inherited microorganisms and determine the effect of changing costs associated with incompatibility, infection-related fecundity loss and number of mates in ideal populations of social insects. The model predicts that infections of...
متن کاملEffects of A and B Wolbachia and host genotype on interspecies cytoplasmic incompatibility in Nasonia.
Wolbachia endosymbionts cause postmating reproductive isolation between the sibling species Nasonia vitripennis and N. giraulti. Most Nasonia are doubly infected with a representative from each of the two major Wolbachia groups (A and B). This study investigates the role of single (A or B) and double (A and B) Wolbachia infections in interspecies cytoplasmic incompatibility (CI) and host genomi...
متن کاملBidirectional cytoplasmic incompatibility and the stable coexistence of two Wolbachia strains in parapatric host populations.
Wolbachiaare intracellular bacteria which are very widely distributed among arthropods. In many insect species Wolbachiaare known to induce cytoplasmic mating incompatibility (CI). It has been suggested that Wolbachiacould promote speciation in their hosts if parapatric host populations are infected with two different Wolbachiastrains causing bidirectional mating incompatibilities. A necessary ...
متن کاملTranscriptome Sequencing Reveals Novel Candidate Genes for Cardinium hertigii-Caused Cytoplasmic Incompatibility and Host-Cell Interaction
Cytoplasmic incompatibility (CI) is an intriguing, widespread, symbiont-induced reproductive failure that decreases offspring production of arthropods through crossing incompatibility of infected males with uninfected females or with females infected with a distinct symbiont genotype. For years, the molecular mechanism of CI remained unknown. Recent genomic, proteomic, biochemical, and cell bio...
