SEED - Seeds, Environment, Epigenetics and Development

The team's aim is to elucidate the regulatory mechanisms involved in the acquisition of various components of the physiological quality of the seed during its development and to gain a better understanding of their adaptive plasticity when the mother plant is subjected to (a)biotic constraints.

During their development, seeds gradually acquire a set of characteristics that will determine their germination performance, a crucial factor in the establishment of plant communities and therefore crop yields. These traits include germination, primary and secondary dormancy, tolerance to desiccation and seed longevity, and the ability to maintain vigour during dry storage.

Our work focuses on legumes such as the model plant Medicago truncatula, pea, bean and soybean. Protein-rich legumes with the ability to fix atmospheric nitrogen are emerging as the crop of choice for meeting the dual challenge of food security and sustainable agriculture. An additional lever for stabilising or even increasing yields is the production of vigorous seeds of high germination quality. Other models, notably tomato, are also being studied in collaborative projects with the seed industry.
