Abstract

Male D. melanogaster fruitflies transfer accessory gland proteins (Acps) together with sperm at mating. These Acps have striking effects on male and female fitness and are subject to unusually strong natural selection. This system therefore provides a unique model of adaptive evolution at the genetic level. We aim to investigate the evolutionary and functional significance of Acps by using existing, and by creating new Acp mutant strains and testing them in rigorously defined, large-scale fitness assays. We will test which sex benefits from the transfer of Acps, test directly for the involvement of Acps in sperm competition, test the extent of functional redundancy between Acps and test the effect of the presence of sperm on the magnitude of responses to Acps.
