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 ...
WebCytokinins 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).
WebPhytohormones are plant hormones. They are organic substances that facilitate regulating the growth of a plant and its development. Plant hormone signals are incorporated at the gene-network level, and their signaling pathways act non-redundantly. Examples are auxin, gibberellins, cytokinins. diamond cut bowling ball resurfacing padsCytokinins (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.
