The developed researches lead in the Agroecology Joint Research Unit help to understand the biotics interactions particularly those between plants to plants and between plants to microorganisms. The analysis focuses on agrosystems with the aim to design innovative and environment-friendly systems. In that way, the developed researches answer two major stakes:
• Analyze, understand and act on the interactions and regulations within communities with various spatial and temporal scales;
• Offer innovative systems of cultures to ensure a good agricultural production in sufficient amount, while respecting the environment
These researches are led to various levels of integration from the molecule to the community and different spatiotemporal scales like microcosm, farm plot, landscape, crop cycle, rotation. They implement complementary expertises such as agronomy; ecology; biology; physiology and ecophysiology; genetics; microbiology and modelling.
