      abstract     = {Plant carbon dioxide fixation and subsequent
                      photoassimilates allocation are fundamentally important for
                      survival, growth and yield of plants. Since carbon
                      distribution in a plant is highly dynamic its investigation
                      is a unique challenge. Radiotracers, such as radioactive
                      carbon dioxide 11CO2 can be administered to a leaf or canopy
                      for tracing photoassimilate distribution within a plant. The
                      3D distribution of the 11C tracer can be monitored with a
                      positron emission tomograph (PET) in order to obtain carbon
                      transport parameters for functional phenotyping. For
                      labelling plants we established a gas exchange system for
                      both measuring gas exchange of leaves and administering
                      11CO2 to the plant. Handling the radioactive carbon dioxide
                      safely requires special precautions which are implemented in
                      the system. Here, we present results of the first gas
                      exchange measurements of pea (Pisum sativum) under drought
                      stress as well as images of 11C allocation into the root
                      measured with the PET system ‘PlanTIS’. For an improved
                      3D visualization of 11C transport a new PET system
                      (phenoPET) was constructed, which is currently under
                      evaluation. First experimental results on plants with both
                      phenoPET and the gas exchange system are expected by mid of
                      2016. In future, it is planned to automatize plant
                      transport, labeling and tracer measurement. All
                      installations combined will facilitate dynamic monitoring
                      and quantification of carbon assimilation with regards to
                      different phenotypes and under controlled environmental
                      conditions.},
