Two recent studies in Drosophila demonstrate that overexpression of proteins required for centriole duplication can not only induce centriole over-duplication in cells containing centrioles, but can also drive de novo centriole assembly in unfertilized eggs that initially lack centrioles. These studies offer a new perspective on the mechanisms that control centriole duplication.
