      abstract     = {Positron Emission Tomography (PET) is a potent tool in
                      plant sciences to measure allocation and transport processes
                      in vivo. Especially the radioisotope Carbon-11 is of major
                      interest as it can be administered as 11CO2 to leaves and
                      used as a tracer to monitor the flow of photoassimilates
                      within complex 3D structures such as roots.However, in the
                      past, PET studies on plants have primarily been conducted on
                      clinical or preclinical PET scanners. These scanners have
                      the drawback of being horizontally orientated and typically
                      not optimized for a plant-friendly environment, including
                      suboptimal temperature, humidity and light conditions.
                      Studies conducted on plant dedicated scanners have often
                      lacked a full characterization, quantitative image
                      reconstruction (including attenuation correction of
                      individual samples) and data analysis pipeline.In this
                      poster we present the establishment of a complete routine
                      Carbon-11 PET pipeline for plants. This pipeline begins with
                      a custom PET facility for plants, which comprises the
                      production and administration of 11CO2, gas exchange
                      measurement, and a climate chamber with a fully
                      characterized and calibrated plant-dedicated PET scanner,
                      the phenoPET. It also includes workflow protocols to measure
                      up to four plants per day and ensures that data from
                      individual plants in measuring series can be reliably and
                      quantitatively compared. Additionally, the application of an
                      in-house developed compartmental model for long-distance
                      transport allows us to quantify and analyze flow velocities
                      of the tracer and exchange rates with other tissues along
                      the transport pathways, including error calculation.},
