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 کاملA genetic test of the mechanism of Wolbachia-induced cytoplasmic incompatibility in Drosophila.
Cytoplasmic bacteria of the genus Wolbachia are best known as the cause of cytoplasmic incompatibility (CI): many uninfected eggs fertilized by Wolbachia-modified sperm from infected males die as embryos. In contrast, eggs of infected females rescue modified sperm and develop normally. Although Wolbachia cause CI in at least five insect orders, the mechanism of CI remains poorly understood. Her...
متن کاملMale development time influences the strength of Wolbachia-induced cytoplasmic incompatibility expression in Drosophila melanogaster.
Cytoplasmic incompatibility (CI) is the most widespread reproductive modification induced in insects by the maternally inherited intracellular bacteria, Wolbachia. Expression of CI in Drosophila melanogaster is quite variable. Published papers typically show that CI expression is weak and often varies between different Drosophila lines and different labs reporting the results. The basis for thi...
