WebPlant b will produce a flower at its apical meristem. Once the flower is gone, plant b will grow taller, but only from growth of lateral meristems. Both plants will produce flowers at the same time, but plant b will have more of them. Once the flower is gone, the apical meristem will develop again, and plant b will continue to grow from that stem. 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). The first cytokinin discovered was an adenine ...

WebCytokinins were discovered as kinetin. Kinetin does not occur naturally but scientists later discovered several natural (example – zeatin) and synthetic cytokinins. Natural cytokinins exist in root apices and developing shoot buds – areas where rapid cell division takes place. Effects. Help in the formation of new leaves and chloroplast. WebHow plants respond to hormones. The five major groups of plant hormones — auxins, cytokinins, gibberellins, ethylene, and abscisic — acid are distinguished by their chemical structures and the response they evoke within the plant (see Table 4.1). For any cell to respond to a hormone it must be competent to perceive the chemical.

WebAll the naturally-occurring cytokinins are substituted purines. The usual way of naming a cytokinin is to express it as a substituted 6-amino purine or as N 6 -substituted adenine. In 1956, Miller isolated the first cell-division inducing factor from autoclaved herring sperm DNA which they named kinetin and identified as 6-(furfurylamino) purine.

WebCytokinins and auxins are common hormones used in plant tissue culture, and the ratios of these two groups of plant hormones affect most major growth periods during a plant’s lifetime. Cytokinins counter the apical dominance induced by auxins; the two hormones in conjunction with ethylene promote abscission of leaves, flower parts, and fruits. thebaesickzWebCytokinins help to produce all except.
