Sucrose is taken up and accumulated by cotyledons of Ricinus communis L. Autoradiographic studies reveal a predominant accumulation of sucrose in the phloem of the cotyledons. The export of sucrose ...

While the movement of water through xylem tissue is relatively well understood, the movement of solute-laden sap through phloem is not. One possibility is the ‘pressure flow hypothesis’ proposed by ...

In experiments on transport tissues in plants, researchers were able to identify factors of crucial importance for the formation of the plant tissue known as phloem. These factors differ from all ...

Researchers have combined traditional genetic approaches with 3-D reconstructions from scanning electron microscopy to discover and characterize genes regulating the development of plant sieve ...

Cu is an essential element for plant growth, but the molecular mechanisms of its distribution and redistribution within the plants are unknown. Here, we report that Yellow stripe-like16 (YSL16) is ...

Sieve elements are a key component of phloem, the conductive tissue through which plants transport carbohydrates and a wide range of signalling molecules. Elongated cylindrical cells are capped at one ...
