sieve tube elements

This increases the hydrostatic pressure of the sieve tube elements.

Phytoplasmas are able to move within the phloem from source to sink, and they are able to pass through sieve tube elements.

Organic compounds such as sucrose produced by photosynthesis in leaves are distributed by the phloem sieve tube elements.

In leaves, companion cells help in moving the sugar produced by photosynthesis in the mesophyll tissue into the sieve tube elements.

Auxin (a phytohormone) when sieve tube elements undergo apoptosis tryptophan is converted to auxins.

Other molecules like amino acids, hormones, and even messenger RNAs are also transported in the phloem through sieve tube elements.

The sieve tube elements lack nuclei and ribosomes, and their metabolism and functions are regulated by the adjacent nucleate companion cells.

Sap is the fluid transported in xylem cells (tracheids or vessel elements) or phloem sieve tube elements of a plant.

In plant anatomy, sieve tube elements, also called sieve tube members, are a specialised type of elongated cell in the phloem tissue of flowering plants.
