Gene expression changes in male accessory glands during ageing are accompanied by reproductive decline in Drosophila melanogaster.

Molecular ecology - 1 Dec 2017

Koppik Mareike, Fricke Claudia

Abstract excerpt

Senescence is accompanied by loss of reproductive functions. Here, we studied reproductive ageing in Drosophila melanogaster males and asked whether the expected decline in male reproductive success is due to diminished functionality of the male accessory gland (AG). The male AG produces the majority of seminal fluid proteins (SFPs) transferred to the female at mating. SFPs induce female postmating changes and...
