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.},
