The objective is to create a meeting of leading scientists in plant biology and to promote basic scientific research as a lever for the implementation of sustainable agricultural practices. Dr Rouached (co-organizer of this symposium) will organize the second edition of MBSA in his future university (Michigan State University-USA) in 2022. The initiation of the organization of this symposium will therefore have an assured international impact and will be sustainable. The initiation of this cycle of MBSA conferences in Montpellier will therefore have a maximum leverage effect on the funds allocated by the Agropolis foundation.
