Proteins and peptides in Drosophila melanogaster seminal fluid induce mated females to increase their rates of egg deposition. One seminal-fluid protein, ovulin (Acp26Aa), stimulates an early step in the egg-laying process, the release of oocytes by the ovary. Ovulin, upon transfer to females, is cleaved sequentially within the mated female's reproductive tract. Here, we show that systemic ectopic expression of ovulin is sufficient to stimulate ovulation in unmated females. By using this assay t ...[more]
