Introduction In angiosperms, the phloem sieve tube system (STS) delivers macromolecules, nutrients and signaling molecules between different tissues and organs to modulate plants growth and development and coordinate responses to environmental cues [1]. Webb1 jan. 2001 · CmPP16 messenger RNA (mRNA) is present in phloem tissue, whereas protein appears confined to sieve elements (SE). Microinjection and grafting studies revealed that CmPP16 moves from cell to cell, mediates the transport of sense and antisense RNA, and moves together with its mRNA into the SE of scion tissue.
WebbPhloem is a specialised living tissue that transports amino acids and sugars from the leaves (source) to the growing parts of the plant (sink) in a process called translocation. This process is bi-directional. A source is a plant region that generates organic compounds, such as amino acids and sugars.
