Cytokinin in plants
WebThe cytokinin-mediated up-regulation of CCS52 was in line with the data in Arabidopsis, where cytokinin, through the cytokinin-activated B-type response regulator ARR2, directly up-regulates the expression of the CCS52A1 gene encoding an activator of an ubiquitin ligase complex (the anaphase-promoting complex/cyclosome) and mediating ... WebJan 15, 2024 · Pioneers of plant biology such as Charles Darwin and Julius von Sachs had already addressed aspects of phytohormone activities in plant growth and development even before these substances had been discovered, through roles in tropisms (Darwin, 1880; Sachs, 1880). The identification of the first auxin and cytokinin followed some …

Cytokini … WebMar 5, 2014 · Kinetin was the first cytokinin discovered and so named because of the compounds ability to promote cytokinesis (cell division). Though it is a natural compound, It is not made in plants, and is therefore usually considered a "synthetic" cytokinin (meaning that the hormone is synthesized somewhere other than in a plant).
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).
