説明
<jats:title>Significance</jats:title> <jats:p> This paper shows how a male-provided seminal protein triggers postmating behavioral changes in that male's mate. Specifically, it shows that the <jats:italic>Drosophila</jats:italic> seminal protein ovulin induces females to ovulate by stimulating females' octopaminergic signaling. This is significant in revealing how a male signal connects to and modulates female physiology to enhance the reproductive capacity of both parties. That this particular seminal protein acts as an upstream regulator of a preexisting physiological pathway in the female also provides a mechanism for how rapidly evolving reproductive proteins (such as ovulin) can effect changes in reproductive behaviors even though conserved signaling systems (such as octopamine) mediate those changes. </jats:p>
