WebSince cytokinins promote cell division, it is interesting that they should show binding affinity toward an enzyme that inhibits DNA methylation. Many synthetic diphenyl urea derivatives, despite their vastly different structures from adenine-type cytokinins, show greater activity, on a molar basis, than adenine-type cytokinins. WebOct 1, 2014 · Cytokinin is generally considered to promote mitotic cell division in the shoot, but differentiation and transition to the endocycle in the root. Here we consider recent data on the inputs by which cytokinins positively and negatively regulate transitions through the cell cycle. Cytokinin positively regulates cell division and also serves a key ...

WebPlant Growth Promoters – They promote cell division, cell enlargement, flowering, fruiting and seed formation. Examples are auxins, gibberellins and cytokinins. Plant Growth Inhibitors – These chemicals inhibit growth … 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.
