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.},
