WebOct 6, 2024 · Common cytokinin derivatives are isopentenyl adenine (iP), trans-zeatin (tZ), and cis-zeatin (cZ). In addition, reduction of the double bond in the tZ saturated side chain, which is catalyzed by a zeatin reductase, forms dihydrozeatin (Mok and Mok 2001). Cytokinins are synthesized in bacteria, fungi, algae, and higher plants. WebAHK3, and CRE1/AHK4. To study the cytokinin–receptor interaction, we used 25 derivatives of potent cytokinin N6-benzyladenine (BA) with substituents in the purine heterocycle and/or in the side chain. The study was focused primarily on individual cytokinin receptors from Arabidopsis.
WebIn the following 40 years, several cytokinin species have been identified from various plant species (35, 43). These studies demonstrated that natural plant cytokinins are adenines which have substituted at the N6 terminal either an isoprene-derived side chain (isoprenoid cytokinins), or an aromatic derivative side chain (aromatic cytokinins). WebJul 11, 2024 · Cytokinin constitutes a vital group of plant hormones regulating several developmental processes including growth, cell division, and have a strong influence on grain yield. Chemically, they are the …
WebCytokinin ribosides (N(6)-substituted adenosine derivatives) have been shown to have anticancer activity both in vitro and in vivo. This study presents the first systematic analysis of the relationship between the chemical structure of cytokinins and their cytotoxic effects against a panel of human cancer cell lines with diverse histopathological origins.
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.
