In higher plants, the phloem acts not only as a conduit for photosynthates but also as a dynamic signalling highway for macromolecules such as RNAs. Messenger RNAs (mRNAs), small interfering RNAs and ...

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 ...

A tiny region at the root tip has been found to be responsible for orchestrating the growth and development of the complex network of vascular tissues that transport sugars through plant roots. A tiny ...

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 ...

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 ...

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 ...
