      abstract     = {· Background and Aims: Plants store carbohydrates for
                      later use during, e.g., night, drought, and recovery after
                      stress. Carbon allocation presents the plant with tradeoffs,
                      notably between growth and storage. We asked how this
                      tradeoff works for cassava (Manihot esculenta)pre- and
                      post-storage root (SR) formation and if manipulation of the
                      number of storage organs and leaf growth rate might increase
                      yield. · Methods: We developed a functional-structural
                      plant model, called MeOSR, to simulate carbon partitioning
                      underlying cassava growth and SR formation in conjunction
                      with the root system's three-dimensional (3D) architecture
                      (RSA). We validated the model against experimental data and
                      simulated phenotypes varying in the number of SR and leaf
                      growth rate. · Results: The simulated 3D RSA and the root
                      mass closely represented those of field-grown plants. The
                      model simulated root growth and associated carbon allocation
                      across development stages. Substantial accumulation of
                      non-structural carbohydrates (NSC) preceded SR formation,
                      suggesting sink-limited growth. SR mass and canopy
                      photosynthesis might be increased by both increasing the
                      number of SR and the leaf growth rate. · Conclusion: MeOSR
                      offers a valuable tool for simulating plant growth, its
                      associated carbon economy, and 3D RSA over time. In the
                      first month, the specific root length increased due to root
                      branching, but in the third month, it decreased due to
                      secondary root growth. The accumulation of NSC might
                      initiate SR development in cassava. Cassava growth is
                      relatively slow during the first 3 months, and a faster crop
                      establishment combined with a greater SR growth might
                      increase yield.},
