Cytokinins (CK) are a class of plant hormones that promote cell division, or cytokinesis, in plant roots and shoots. They are involved primarily in cell growth and differentiation, but also affect apical dominance, axillary bud growth, and leaf senescence.

A cytokinin is any of a number of plant hormones that influence growth and the stimulation of cell division. Cytokinins are synthesized in the roots and travel through the xylem to the leaves and fruits, where they are required for normal growth and cell differentiation.

Cytokinins are a group of plant growth regulators which are primarily involved in performing cell division in plant roots, shoot system. This hormone helps in promoting the cell’s growth, development, differentiation, affecting apical dominance and delay in leaf senescence.

Cytokinins (CKs) are adenine-derived, small-molecule plant growth regulators that control aspects of almost all plant growth and development processes.

2015年11月27日 · Cytokinins comprise a family of signaling molecules essential for regulating the growth and development of plants, acting both locally and at a distance. Although much is known about their biosynthesis and transport, important open questions remain. What are cytokinins? Cytokinins are a well-studied family of plant hormones.

Cytokinins are compounds with a structure close to adenine. They are usually linked to an isopentenyl side chain. Kinetin was the first artificial cytokinin to be discovered. It was isolated from herring sperm and named after its ability to promote cell division.

2023年5月27日 · Cytokinins (CKs) are important plant hormones that regulate a variety of biological processes implicated in plant development and stress responses.

2002年3月27日 · Cytokinins are N6 substituted adenine derivatives that affect many aspects of plant growth and development, including cell division, shoot initiation and growth, leaf senescence, apical dominance, sink/source relationships, nutrient uptake, phyllotaxis, and vascular, gametophyte, and embryonic development, as well as the response to biotic and a...

2023年1月9日 · Here, we will focus on cytokinins — a unique class of plant hormones — giving clues on their metabolism, on how they are perceived by cells and how cells change their activity in response to it. Most of the data presented have been derived by studies conducted on Arabidopsis thaliana, a plant used as a model system in plant science.

Skoog, Strong and Miller proposed the definition of cytokinin. It is a compound which besides other activities induces cytokinesis, i.e., cell division in the various plant organs grown in a medium containing an optimal concentration of auxin.
