The name “Kinetin” or “Kinins” was later on replaced with the name “cytokinin” because the former name conflicted with the same term used in animal biochemistry. A cytokinin is now defined ... WebCytokinin promotes shoot branching by activating axillary buds, but its mechanism of action in Arabidopsis (Arabidopsis thaliana) in this process is unclear.

WebCytokinins control critical aspects of plant development and environmental responses. Perception of cytokinin ultimately leads to the activation of proteins belonging to the type-B Response Regulator family of cytokinin response activators. In Arabidopsis thaliana, ARR1 is one of the most abundantly expressed type-B Response Regulators. 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. There are two types of cytokinins: adenine-type … See more The idea of specific substances required for cell division to occur in plants actually dates back to the German physiologist J.

As stated in the latest review (Yu et al, 2024), cytokinin promotes and maintains plant growth under normal growth conditions, but its role in salt stress is slightly different. Under mild ...
WebFeb 23, 2009 · Abstract. The hormone cytokinin promotes cell differentiation in plant roots by repressing both auxin transport and responses to auxin at the boundary between the meristem and the root elongation zone. In plants, populations of undifferentiated cells called meristems serve as the source of all new growth throughout post-embryonic development.
