Webb8 aug. 2016 · While the loading phloem in source organs (minor veins) is responsible for the active loading of photo assimilates into the phloem, the unloading phloem in sink organs delivers assimilates to sink tissues, and the transport phloem (generally found in the main leaf veins of petioles, stems and primary roots, along the path from sources to … WebbAbstract The transport events from the sieve elements to the sites of utilization within the recipient sink cells contribute to phloem unloading. The phenomenon links sink metabolism and/or compartmentation with phloem transport to, and partitioning between, sinks. The nature of the linkage depends upon the cellular pathway and mechanism of …
