      abstract     = {Development of a root system and management of its various
                      functions suited for the local dynamic resource situation
                      and environmental conditions is critical for plant survival,
                      performance and yield. 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.
                      Unfortunately, the opaque nature of soil prevents
                      observation of such processes by simple means and while a
                      number of approaches for observing 2D root development such
                      as rhizotrons have been applied successfully, roots
                      naturally develop interacting with their 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 non-invasive
                      visualization and quantification of root system architecture
                      traits in soil such as root length and mass, as well as
                      internal structures of belowground storage organs. Positron
                      emission tomography (PET) using short-lived radiotracer
                      11CO2 provides additional imaging of the distribution of
                      newly fixed photoassimilates. Also Photoassimilate flow
                      characteristics can be extracted from PET data with a
                      model-based analysis. We show here application of both
                      techniques for visualization and quantification of root
                      system architecture, anatomy and photoassimilate allocation
                      on a range of species and developmental stages including
                      barley, maize, sugar beet and pea.},
