The intermittent and synchronized production of large numbers of seeds or flowers by plant populations is called "masting" or "mast seeding". A variety of factors influence the likelihood of mast seeding. Two major factors are internal resource level (such as carbon, nitrogen, and phosphorus content) and external environmental signals (low temperature and drought). How these internal and external factors interact to induce flowering and fruiting is a central question in plant biology. In this symposium, we will introduce a new multidisciplinary approach to address the question, and will demonstrate that synthesis of molecular biology, ecology, and mathematical modeling is necessary for in-depth understanding of the mechanism of mast seeding.
