Cytokinins plant hormone
WebQuestion 1b. Textbook Question. Test your knowledge of the five major classes of plant hormones (auxins, cytokinins, gibberellins, abscisic acid, ethylene) by matching one hormone to each lettered box. (Note that some hormones will match up to more than one box.) Question 2a. WebCytokinins are essential plant hormones that control cell division, shoot meristem initia-tion, leaf and root differentiation, chloroplast biogenesis, stress tolerance, and senescence. Together with auxin, another plant hormone, cytokinins can reprogram terminally differen-tiated leaf cells into stem cells and support shoot regeneration ...

WebCytokinins increase the resistance of plants to adverse factors such as high and low temperatures and certain disease. The nature of the action of cytokinins in bringing about these effects is still unknown. Naturally-occurring cytokinins have been implicated in host-parasite relationship. WebKinetin (/'kaɪnɪtɪn/) is a cytokinin -like synthetic plant hormone that promotes cell division in plants. [1] Kinetin was originally isolated by Carlos O. Miller [2] and Skoog et al. [3] as a compound from autoclaved herring sperm DNA that had cell division-promoting activity. It was given the name kinetin because of its ability to induce ...

WebPlant Hormones Types. The plant hormones such as auxin, abscisic acid, ethylene, gibberellins, cytokinins, salicylic acid, etc. help the plant function under stress, helping the plant to tolerate the environmental stresses.

They are involved primarily in cell growth and differentiation, but also affect apical dominance, axillary bud growth, and leaf senescence. There are two types of cytokinins: adenine-type cytokinins represented by kinetin shaq outfit last nightWebHormone action At the cell level hormones attach to a protein receptor which sends a signal down a transduction pathway to switch on particular genes. Through transcription and translation this leads to production of an enzyme protein which actually causes the change in plant growth.
