Abstract

Early animal development is controlled by maternally encoded RNAs and proteins, which are loaded into the egg during oogenesis. Oocyte maturation and egg activation trigger changes in the translational status and the stability of specific maternal mRNAs. Whereas both maturation and activation have been studied in depth in amphibians and echinoderms, only recently have these processes begun to be dissected using the powerful genetic and molecular tools available in Drosophila. This review focuses on the mechanisms and functions of regulated maternal ...

Abstract

Wolbachia are intracellular microorganisms that form maternally-inherited infections within numerous arthropod species. These bacteria have drawn much attention, due in part to the reproductive alterations that they induce in their hosts including cytoplasmic incompatibility (CI), feminization and parthenogenesis. Although Wolbachia's presence within insect reproductive tissues has been well described, relatively few studies have examined the extent to which Wolbachia infects other tissues. We have examined Wolbachia tissue tropism in a number of representative insect hosts by western blot, dot blot hybridization ...

Abstract

A novel protein required for RNA interference in Drosophila, Armitage, was identified in a screen for genes involved in embryonic axis formation. In armitage mutants, oocyte polarity and the regulation of oskar mRNA translation are impaired, suggesting that RNA silencing regulates the first steps of Drosophila development. ...
