What is cytokinin explain?
Cytokinins are plant-specific chemical messengers (hormones) that play a central role in the regulation of the plant cell cycle and numerous developmental processes. Cytokinins were discovered by F Skoog, C Miller, and co-workers during the 1950s as factors that promote cell division (cytokinesis).
What is cytokinin and its function?
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.
What are the two types of cytokinins?
There are two types of cytokinins: adenine-type cytokinins represented by kinetin, zeatin, and 6-benzylaminopurine, and phenylurea-type cytokinins like diphenylurea and thidiazuron (TDZ).May 25, 2022
What is the other name of cytokinins?
This active compound was named as Kinetin because of its ability to promote cell division and was the first cytokinin to be named. Kinetin was later identified to be 6-furfuryl-amino purine. Later on, the generic name kinin was suggested to include kinetin and other substances having similar properties.
What is another name for cytokinin?
This active compound was named as Kinetin because of its ability to promote cell division and was the first cytokinin to be named. Kinetin was later identified to be 6-furfuryl-amino purine. Later on, the generic name kinin was suggested to include kinetin and other substances having similar properties.
Is cytokinin also known as kinetin?
Kinetin is a cytokinin-like synthetic compound that regulates cell growth in plants. Kinetin was the first cytokinin discovered. It is also adenine-based. It was given the name kinetin because of its ability to induce cell division, provided that auxin was present in the medium.
Why are cytokinins named so?
Cytokinins are a class of plant growth substances that promote cell division, or cytokinesis, in plant roots and shoots.
What is cytokinin in simple words?
cytokinin, any of a number of plant hormones that influence growth and the stimulation of cell division. Cytokinins are synthesized in the roots and are usually derived from adenine.
What is the main function of cytokinins?
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.
What is the function of cytokinins in regulation of the cell cycle?
Cytokinin positively regulates cell division and also serves a key role in establishing organization within shoot stem cell centers. Both auxin-dependent and auxin-independent mechanisms have been uncovered by which cytokinin stimulates the endocycle in roots.
What are cytokinins give an example?
Cytokinin is a class of plant growth hormones that are active in promoting cell division, growth, differentiation, and other physiological processes. Examples are kinetin, zeatin, and benzyl adenine.Mar 2, 2022
