      abstract     = {The plant nutrient phosphorus (P) is spread throughout the
                      plant within the transpiration stream after uptake in the
                      form of phosphate via the roots. Short-term distribution is
                      therefore strongly dependent on transpiration rather than on
                      sinks, so that P mainly enters adult leaves. The objective
                      of this work was to investigate the transport of phosphate
                      in leaf veins and its distribution within the leaf.
                      Experiments were performed with broad bean (Vicia faba L.
                      var. Scirocco) using radioactively labeled phosphate. In a
                      relatively new approach, the tracer was monitored by a
                      sensitive imaging plate using Fujifilm's Bioimaging Analyzer
                      System. Radioactive label could be monitored in fresh leaves
                      (without fixing) using exposure times of only 5-20 min. For
                      this reason, the method offered the possibility to obtain
                      several subsequent autoradiographic images of the same
                      sample after different feeding times. Phosphate tracer
                      quickly reached small veins, which were then more intensely
                      labeled than the tissue between them. Within the first 15
                      min, intercostal fields were only slightly stained. After
                      application of phosphate tracer onto the leaf blade, export
                      from the leaf was pronounced and started within 30 min.
                      Phosphorus is effectively redistributed from adult leaves to
                      sinks such as the terminal bud or growing root tips. Using
                      the imaging method, an impression of the high velocity and
                      effectiveness of this process was obtained. The results
                      furthermore imply that leaf veins may be one of the most
                      important locations where exchange between xylem and phloem
                      transport takes place, although exchange between xylem and
                      phloem was also observed in the shoot axis and in the
                      petioles.},
