      abstract     = {Seed filling, root and nodule development are some of the
                      key processes involved in abiotic stress resistance.
                      However, these are complex processes hidden either by pod
                      tissue (seed filling) or by soil (roots and nodules), so
                      studying them quantitatively in-vivo is challenging.
                      Non-invasive (3D) imaging techniques such as magnetic
                      resonance imaging (MRI) can be used to investigate hidden
                      structural development both above- and belowground.
                      Co-registered positron emission tomography (PET) allows the
                      acquisition of functional information by mapping of recent
                      carbon investment of the plant and its dynamics e.g. in
                      response to stress. For tasks not requiring spatial
                      (volumetric) resolution, such as monitoring changes in pod
                      water and dry-matter content, low field nuclear magnetic
                      resonance relaxometry with portable devices (pNMR) can be
                      applied. Such devices allow sensor-like applications in the
                      greenhouse and the field. In the current contribution we
                      will demonstrate the application of MRI to follow the
                      development of root system architecture in soil grown pea
                      and bean genotypes and monitor the progress of nodulation by
                      repeated 3D mapping of nodule distribution. By correlating
                      these maps with PET, monitoring carbon import, we get first
                      insights into the functionality of nodules in the soil.
                      Additionally we will demonstrate monitoring changes of bean
                      pod water and dry-matter contents over the course of several
                      weeks with pNMR. We discuss the potential and challenges of
                      all three techniques (MRI, PET and pNMR) for application in
                      legume research.},
