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 ...
Figure 2: The plant vascular network and the development of the phloem sieve-tube system. The discovery of a new RNA-binding protein that is localized exclusively in the sieve-tube system and shows ...
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 ...
Phloem diseases, including the economically devastating citrus greening, are particularly difficult to study because phloem cells -- essential for plant nutrient transport -- are difficult to access ...
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 ...
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 ...
Figure 3: CHER1 localizes to TGN, nascent cell plates and in phloem precursor cells to the sites of forming sieve plates. Figure 4: Continuous vesicle trafficking is required for establishing CHER1 ...
These are distributed differently in roots and stems. In the root, the xylem forms a central column. It forms a solid support. The phloem is towards the centre, outside the xylem. Any green part of a ...
The phloem moves food substances that the plant has produced by photosynthesis to where they are needed for processes such as: Transport of substances in the phloem is called translocation. Phloem ...
