چکیده
MARIANA F. WOLFNER Department of Molecular Biology and Genetics Cornell University Ithaca, NY 14853 USA E-mail: [email protected] DOI: 10.1002/mrd.22338 Mating regulates the available combinations of neuromodulators in Drosophila reproductivetract regions. This results in a combinatorial “code” of neuromodulators that changes with place and time, and is proposed to coordinate functional changes along the reproductive tract in response to mating (Current Biology. 24, 731–737). These false-colored images show octopamine, serotonin, dromyosuppressin, or nNOS immunoreactivity in different regions of the Drosophila reproductive tracts of unmated females or of females at different times post-mating.

Mating Regulates Neuromodulator Ensembles at Nerve Termini Innervating the Drosophila Reproductive Tract
Upon mating, regions of the female reproductive tract mature and alter their function [1-3], for example to facilitate storage of sperm or control the release of eggs [4-6]. The female's nervous system and neuromodulators play important roles in her responses to mating [7-13]. However, it is difficult to reconcile the reproductive tract's many changing but coordinated events with the small set ...

MARIANA F. WOLFNER Department of Molecular Biology and Genetics Cornell University Ithaca, NY 14853 USA E-mail:[email protected] Nitric oxide (NO) plays important roles in numerous physiological processes in many animals. In mammals, NO regulates muscle contractions in the female reproductive tract [e.g. Ekerhovd et al. (1997) Hum. Repro. 12: 301-305; Yampalli et al. (1993) Endocrinol...
متن کاملMating, seminal fluid components, and sperm cause changes in vesicle release in the Drosophila female reproductive tract.
Mating induces changes in female insects, including in egg production, ovulation and laying, sperm storage, and behavior. Several molecules and effects that induce these changes have been identified, but their proximate effects on females remain unexplored. We examined whether vesicle release occurs as a consequence of mating; we used transgenic Drosophila that allow monitoring of secretory gra...
متن کاملSensory Neurons in the Drosophila Genital Tract Regulate Female Reproductive Behavior
Females of many animal species behave very differently before and after mating. In Drosophila melanogaster, changes in female behavior upon mating are triggered by the sex peptide (SP), a small peptide present in the male's seminal fluid. SP activates a specific receptor, the sex peptide receptor (SPR), which is broadly expressed in the female reproductive tract and nervous system. Here, we pin...
متن کاملPostmating transcriptional changes in reproductive tracts of con- and heterospecifically mated Drosophila mojavensis females.
In internally fertilizing organisms, mating involves a series of highly coordinated molecular interactions between the sexes that occur within the female reproductive tract. In species where females mate multiply, traits involved in postcopulatory interactions are expected to evolve rapidly, potentially leading to postmating-prezygotic (PMPZ) reproductive isolation between diverging populations...
