Sieve elements are a key component of phloem, the conductive tissue through ... by a sieve plate and arranged end-to-end to form sieve tubes which in turn form a network throughout a plant's ...

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 ...

The phloem transports sugars from leaves to roots ... Axial parenchyma, ray parenchyma, sieve tubes, companion cells, cork cambium, the cambium, and plasmodesmata make up the symplast.

researchers must understand in detail the way these pathogens deform the plant phloem cells known as sieve elements and companion cells. Today, many basic questions remain unanswered about how ...

In vascular plants, long-distance transport of photoassimilates is driven by a pressure gradient within the phloem. It is a highly specialised tissue consisting of a network of living, tube-shaped ...

Phloem Sieve tubes Transport products of photosynthesis, including sugars and amino acids, from the leaf to where they are needed. Companion cells Provide the energy required for transporting ...

Strands of cytoplasm run through holes in the sieve plates, connecting the sieve tubes that make up the phloem. Dissolved sugars and amino acids can be transported both up and down the stem.
