We investigate reproductive processes that occur around the time of fertilization. Our molecular/genetic studies focus primarily on Drosophila, because of its genetic/genomic tools and resources, easily manipulated reproductive biology, and role as a model system for understanding analogous processes in people and in insect vectors of disease. One topic that we study, and the one that I will discuss in my seminar, concerns the actions of seminal proteins that female flies receive from their mates. These proteins modify the mated females’ behavior and reproductive physiology. I will describe how males’ seminal proteins work together with females’ molecules and physiology to stimulate egg production and sperm storage within mated females. Then I will describe how evolutionary studies suggest that even though the male and female molecules work together, there are evolutionary pressures that can drive those molecules to evolve rapidly.
