      abstract     = {The short-lived radioisotope 11C can be applied
                      non-invasively to the plant as 11CO2 to follow the flow of
                      recently fixed carbon. This method has allowed for many
                      interesting findings on phloem flow in the past. The
                      combination with PET detection and compartmental modelling
                      has the potential to allow the imaging and quantification of
                      phloem flow in complex 3D structures such as root system or
                      branched shoots. However, this requires an experimental
                      pipeline and facility to label and image plants in a
                      reliable and consistent manner. We will show the key
                      elements of the pipeline we have established in a
                      plant-dedicated radiotracer lab for routine flow imaging
                      along with discussing the advantages and limitation of the
                      approach. Results will be presented on phloem flow
                      velocities simultaneously measured in different root types
                      of maize with statistically relevant numbers of individuals
                      and other 3D examples. Furthermore, results will be
                      presented on phloem flow in different parts of bean shoots
                      and examples for other species.},
