Sexual behavior: how Sex Peptide flips the postmating switch of female flies.
Drosophila male Sex Peptide elicits an amazing variety of postmating responses in mated females, some of which are transmitted via a receptor on specific neurons of the female genital tract. New work shows that neurons expressing the sex-determination gene doublesex (dsx) play a pivotal role in the female postmating switch.
