Phloem transport of sulfur in Ricinus
Planta, 1982Mature leaves of Ricinus communis fed with (35)SO 4 (2-) in the light export labeled sulfate and reduced sulfur compounds by phloem transport. Only 1-2% of the absorbed radiosulfur is exported to the stem within 2-3 h, roughly 12% of (35)S recovered was in reduced form.

Universality of phloem transport in seed plants
Plant, Cell and Environment, 2012ABSTRACTSince Münch in the 1920s proposed that sugar transport in the phloem vascular system is driven by osmotic pressure gradients, his hypothesis has been strongly supported by evidence from herbaceous angiosperms. Experimental constraints made it difficult to test this proposal in large trees, where the distance between source and sink might prove ...

The direction of the long distance transport of solutes in the xylem is governed by transpiration and so takes place from root to shoot. Transport in the reverse direction occurs in a specialised tissue known as phloem (from the Latin word for bark): together xylem and phloem make up the vascular tissue of the plant.

Abstract Flow of photo assimilates into various compartments or biochemical pathways within source and sink regions. In source organs, carbon is allocated to various uses including export. In a sink organ, carbon enters into compartments or is used for synthesis, storage, or energy metabolism.

A multicellular plant with specialised organs can only function effectively if it has an organised transport system. The over-all nutrition and growth of a plant may depend as much on the efficient transfer of nutrients between its component parts as it does on their total synthesis or uptake.

Exactly how nutrient materials travel through the green plant is still a matter for controversy. This review highlights some of the current points of interest.

On the volume-flow mechanism of phloem transport
Planta, 1973A steady-state model of solution flow in a tubular semipermeable membrane is developed for an arbitrary distribution of solute sources and sinks along the translocation path. It is demonstrated that the volume-flow mechanism of phloem transport depends only on the two assumptions: 1.

Intracellular Transport Apparatus of Phloem Fibers
Science, 1964Rotational streaming of cytoplasm occurs in the form of longicellular currents in immature and relatively mature fibers of bean stems. Plastids carried by these currents move continuously on their rotational course from one end of the cell to the other in relatively straight lines.
