Hop-off hop-on: Assimilates on the road

Solutes are subject of constant release and retrieval processes during long distance transport in higher plants. In the stem, sugars and amino acids are used for storage or for nutrition of parenchymatic tissues. Modification of export/import capacities along the transport phloem might provide a powerful tool to enhance the productivity of crop plants.

Automated summary

During long distance transport in higher plants, solutes are continuously released and retrieved, with sugars and amino acids in the stem being used for storage or nourishment of parenchymatic tissues. Modifying export/import capacities along the transport phloem could be a powerful tool for increasing crop plant productivity.
