Transport in biology means carrying substance absorbed or made in the body of an organism to all other parts of its body. In plants, it is only water and minerals that need to be transported to its ...

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 ...

Vascular pathways consisting of interconnected cells act as a system for the transport of carbohydrates in plants. Phloem, the tissue that carries the nutrients, consists of, among other things, the ...

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 ...

The tomato plant's news is carried in code. Molecular messengers carry vital instructions from leaves to far-flung stems, say US researchers. Long-distance traffic in grafted tomato stems switches ...
