      abstract     = {Understanding long-distance transport in plants enables the
                      investigation of functional traits under the influence of
                      diverse environmental factors. Especially carbon
                      partitioning in the phloem is of great interest, as it
                      ensures the growth and survival of higher plants. Despite
                      the long familiarity of these transport mechanisms,
                      quantifying their physical properties remains a complicated
                      task due to the many factors that influence transport. Also,
                      efficiently measuring the flow itself often poses a problem,
                      as many sampling methods are destructive and may distort the
                      allocation. Therefore, non-invasive methods utilising
                      radioactive tracers have been established in plant
                      physiological and ecological research. For example, CO2
                      marked with the short-lived radioisotope 11C can be
                      introduced to the plant as carbon source to investigate
                      carbon partitioning. The tracer inside the plant organs can
                      be detected and localised by positron emission tomography
                      (PET). In order to estimate certain transport properties,
                      the obtained spatially and temporally resolved tracer data
                      can be analysed with mathematical methods. Here, we present
                      the modelling approach of Bühler et al. (2014-2018), who
                      introduced a model family that represents tracer transport
                      in the phloem in several compartments. Between the
                      compartments axial convection as well as lateral exchange
                      can take place. We demonstrate how this modelling framework
                      allows estimation of transport parameters such as plant
                      specific flow velocities and the amount of tracer stored
                      along the transport pathway by fitting them to
                      experimentally obtained data. Finally, we discuss how the
                      modelling framework can be extended to enable analysis of
                      complex datasets from branched plant structures.},
