A whole plant model was build up based on programmable and self-organised morphogenesis processes. The coupling between aboce- and below- ground components of the system is based on two principles: i) self regulation rules from shoot architecture trigger the initiation of new nodal roots, and ii) carbon allocation drives root development.
