Cytoplasmic incompatibility in Australian populations of Drosophila melanogaster.
In Drosophila melanogaster, weak incompatibility in crosses between infected and uninfected strains is associated with a Wolbachia microorganism. Crosses between infected males and uninfected females show a reduction (15-30%) in egg hatch. Progeny tests indicated that the infection is widespread in Australian D. melanogaster populations and that populations are polymorphic for the presence of t...
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...
متن کاملPopulation dynamics of the Wolbachia infection causing cytoplasmic incompatibility in Drosophila melanogaster.
Field populations of Drosophila melanogaster are often infected with Wolbachia, a vertically transmitted microorganism. Under laboratory conditions the infection causes partial incompatibility in crosses between infected males and uninfected females. Here we examine factors influencing the distribution of the infection in natural populations. We show that the level of incompatibility under fiel...
متن کاملCytoplasmic myosin from Drosophila melanogaster
Myosin is identified and purified from three different established Drosophila melanogaster cell lines (Schneider's lines 2 and 3 and Kc). Purification entails lysis in a low salt, sucrose buffer that contains ATP, chromatography on DEAE-cellulose, precipitation with actin in the absence of ATP, gel filtration in a discontinuous KI-KCl buffer system, and hydroxylapatite chromatography. Yield of ...
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...
