      abstract     = {Individual plants vary in their ability to respond to
                      environmental changes. The plastic response of a plant
                      enhances its ability to avoid environmental constraints, and
                      hence supports growth, reproduction, and evolutionary and
                      agricultural success.Major progress in the analysis of
                      above- and belowground processes on individual plants has
                      been made by the application of non-invasive imaging methods
                      including Magnetic Resonance Imaging (MRI) and Positron
                      Emission Tomography (PET).MRI allows for repetitive
                      measurements of roots growing in soil and facilitates
                      quantification of root system architecture traits in 3D.
                      PET, on the other hand, opens a door to analyze dynamic
                      physiological processes in plants such as long-distance
                      carbon transport in a repeatable manner. Combining MRI with
                      PET enables monitoring of short livedCarbon tracer (11C)
                      allocation along the transport paths (i.e. roots visualized
                      by MRI) into active sink structures.To analyse the link
                      between root-internal C allocation patterns and C metabolism
                      in the rhizosphere, we are combining 11CO2 with stable 13CO2
                      labelling of plants. Isotope ratio mass spectrometry (IRMS)
                      analyses of rhizosphere soil is applied to link
                      root-internal C allocation patterns with distribution of 13C
                      in the rhizosphere soil. The metabolically active
                      rhizosphere organisms are subsequently identified based on
                      DNA 13C stable isotope probing.In our presentation we will
                      highlight our approaches for gathering quantitative data
                      from both image-based technologies in combination with
                      destructive analysis that provides insights into the
                      functioning and dynamics of C transport processes in the
                      plant-soil system.},
