This project investigates how flowering plants control the number of sperm cells reaching an ovule to prevent lethal polyspermy. It aims to identify the molecular mechanisms behind these reproductive barriers, particularly focusing on the pollen tube block and its relaxation in certain plant types.
The ultimate goal for the survival of all species on earth is to reproduce.
This uncompromising principle has triggered the evolution of numerous adaptations.
One strategy commonly employed by sexually reproducing eukaryotes is the production of tremendous amounts of sperm to maximize the likelihood of an egg becoming fertilised.
High sperm to egg ratios are, however, associated with an increased risk of supernumerary sperm fusion.
This so-called polyspermy is lethal in many organisms.
