      abstract     = {The development of a root system which is adequate for the
                      respective growing conditions of a plant is critical for
                      survival, performance and yield. Furthermore for “Root
                      Crops” where the yield-relevant organ is developing
                      belowground, the processes leading to amount and quality of
                      the product at harvest also happen among the plants hidden
                      half. 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 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. Magnetic resonance imaging (MRI) is a technique
                      that allows for visualization and quantification of root
                      system architecture traits in soil such as root length and
                      mass but also of internal structures of belowground storage
                      organs. Positron emission tomography (PET) using short-lived
                      radiotracer 11CO2 provides additional imaging of the
                      photoassimilate distribution and flow characteristics can be
                      extracted with a model-based analysis. We show here
                      application of both techniques for visualization and
                      quantification of root system architecture, anatomy and
                      photoassimilate allocation.},
