Self-incompatibility is a widespread genetic system to enforce outcrossing in the flowering plants. Over almost a century, it has attracted interest of two scientific communities. First the population genetics community, for which the well-defined genotype-to-fitness map provides a fertile ground to derive predictive population genetics models. Second the plant molecular biology community, who has described in details the molecular recognition and cellular response pathways in model species. I will describe how combining these two lines of research in the genomic era provides unique perspectives on general questions in evolutionary biology, specifically focusing on the emergence of evolutionary novelty and the structure of regulatory networks.
