Wolbachia 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 کاملEvolution 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 کاملCytoplasmic incompatibility and sperm cyst infection in different Drosophila-Wolbachia associations.
Wolbachia are a group of maternally transmitted obligatory intracellular alpha-proteobacteria that infect a wide range of arthropod and nematode species. Wolbachia infection in Drosophila in most cases is associated with the induction of cytoplasmic incompatibility (CI), manifested as embryonic lethality of offspring in a cross between infected males and uninfected females. While the molecular ...
متن کاملWolbachia transfer from Drosophila melanogaster into D. simulans: Host effect and cytoplasmic incompatibility relationships.
Wolbachia are maternally transmitted endocellular bacteria causing a reproductive incompatibility called cytoplasmic incompatibility (CI) in several arthropod species, including Drosophila. CI results in embryonic mortality in incompatible crosses. The only bacterial strain known to infect Drosophila melanogaster (wDm) was transferred from a D. melanogaster isofemale line into uninfected D. sim...
متن کاملWolbachia-Induced Unidirectional Cytoplasmic Incompatibility and Speciation: Mainland-Island Model
Bacteria of the genus Wolbachia are among the most common endosymbionts in the world. In many insect species these bacteria induce a sperm-egg incompatibility between the gametes of infected males and uninfected females, commonly called unidirectional cytoplasmic incompatibility (CI). It is generally believed that unidirectional CI cannot promote speciation in hosts because infection difference...
