Implication

Tracer experiment demonstrates rapid assimilate translocation to roots and young leaves in illuminated soybean, indicating active sink-source transport during photosynthesis.

Key Points

To examine the pathways and distribution timing of photosynthetic assimilates from mature leaves to sink organs in soybean plants.
Supplied carbon-14 labeled carbon dioxide (14CO2) to a localized area of an illuminated, mature soybean leaf.
Monitored the translocation and rapid accumulation of radioactive labeled assimilates across sink tissues during active photosynthesis.
Radioactive compounds transported rapidly from the treated mature leaf to the root system, shoot apex, and expanding young leaves.
Assimilate export and delivery to sink tissues occurred in the presence of light while source leaf photosynthesis was active.
