...Johanna Talavera Ohlmeyer; Trudi Schüpbach Exit from the cell cycle requires the downregulation of Cyclin/Cdk activity. In the ovary of Drosophila , Encore activity is necessary in the germline to exit the division program after four mitotic divisions. We find that in encore mutant germaria...

...Cheryl Van Buskirk; Nancy C. Hawkins; Trudi Schüpbach ABSTRACT Mutations in the encore (enc) gene of Drosophila melanogaster cause one extra round of mitosis in the germline, resulting in the formation of egg chambers with extra nurse cells. In addition, enc mutations affect the accumulation...

... as nurse cells. We have identified a gene, encore , that is involved both in regulating the number of germline mitoses and in the process of oocyte differentation. Mutations in encore result in exactly one extra round of mitosis in the germline. Genetic and molecular studies indicate that this mitotic...
