                      author: r.metzner@fz-juelich.deThe development of a root
                      system adequate for supplying a plant with water and
                      nutrients under dynamic growing conditions is critical for
                      survival, performance and yield. Particularly for “Root
                      Crops” where the storage organs are developing
                      belowground, the dynamics of the carbon storage of the roots
                      are also highly relevant. The opaque nature of soil prevents
                      direct observation and while a number of approaches for
                      observing 2D root development such as rhizotrons have been
                      applied successfully, roots naturally develop in interaction
                      with the 3D soil environment and form themselves complex 3D
                      structures. Therefore the ability to deep-phenotype the 3D
                      structure and function of roots and other belowground
                      structures non-invasively yields a high potential for
                      gaining new insights into root development, its regulation
                      and responses to stress. Here we present two approaches that
                      allow this kind of investigation: Magnetic resonance imaging
                      (MRI) allows for visualization and quantification of root
                      system architecture traits in soil such as root length and
                      mass, but also of internal structures of storage organs.
                      Positron emission tomography (PET) using short-lived
                      radiotracer 11C provides additional 3D imaging of the
                      photoassimilate distribution. Photoassimilate flow
                      characteristics can be extracted from these data with a
                      model-based analysis. We show here application of both
                      techniques for repeated visualization and quantification of
                      root system architecture, anatomy and photoassimilate
                      allocation of a number of species and developmental stages,
                      including barley, pea and sugar beet.},
