WebAug 14, 2001 · Cytokinins were discovered during the 1950s because of their ability to induce plant cell division ().Shortly after their discovery, Skoog and Miller coined the auxin–cytokinin hypothesis of plant morphogenesis ().The hypothesis predicted that cytokinin, together with auxin, plays an essential role in plant morphogenesis, having a … WebJan 2, 2014 · Cytokinins are N (6) substituted adenine derivatives that affect many aspects of plant growth and development, including cell division, shoot initiation and growth, leaf …

WebCytokinins are N6-substituted adenines and represent an important group of phytohormones with diverse biochemical functions in plants, stimulating cell division and plant growth. The main structural feature of cytokinin nucleosides is the presence of a hydrophobic hydrocarbon moiety at the N6-position of adenosine. bittersweet furniture

WebOther cytokinins identified from the same source are zeatin riboside and its 5-phosphate derivatives with one or more phosphate group, i.e., zeatin ribotide. Both zeatin and … WebCytokinins are adenine derivatives that carry an isoprene-derived or an aromatic side chain at the N6 position of the purine ( Fig. 3.1). In the 1950s, Folke Skoog and colleagues isolated the first cytokinesis-promoting factor, kinetin, from autoclaved herring sperm DNA (Miller et al., 1955a, 1955b ). WebThe biosynthesis of aromatic cytokinins in planta, unlike isoprenoid cytokinins, is still unknown. To compare the final steps of biosynthesis pathways of aromatic and isoprenoid cytokinins, we synthesized a series of nucleoside derivatives of natural cytokinins starting from acyl-protected ribofuranosyl-, 2′-deoxyribofuranosyl- and 5′ … datatypeconverter.parsebase64binary
