Mating‐regulates reproductive‐tract neuromodulators in Drosophila

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 function...

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 ...

The Drosophila melanogaster Seminal Fluid Protease “Seminase” Regulates Proteolytic and Post-Mating Reproductive Processes

Proteases and protease inhibitors have been identified in the ejaculates of animal taxa ranging from invertebrates to mammals and form a major protein class among Drosophila melanogaster seminal fluid proteins (SFPs). Other than a single protease cascade in mammals that regulates seminal clot liquefaction, no proteolytic cascades (i.e. pathways with at least two proteases acting in sequence) ha...

Mating-responsive genes in reproductive tissues of female Drosophila melanogaster.

Male-derived accessory gland proteins that are transferred to females during mating have profound effects on female reproductive physiology including increased ovulation, mating inhibition, and effects on sperm utilization and storage. The extreme rates of evolution seen in accessory gland proteins may be driven by sperm competition and sexual conflict, processes that may ultimately drive compl...

Mating, 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...
