• 7. Design and biological activity of caged cytokinin

抄録

Cytokinins primarily promote cell division to regulate cell growth and differentiation, and also affect apical dominance, axillary bud growth, and leaf senescence. To investigate the detailed responses to cytokinins in plant tissues and cells, the accurate application of cytokinin are essential for the manipulation of cytokinin effects. Caged cytokinins are chemical tools to achieve the accurate application of cytokinins, because the cytokinin level can be temporally and spatially controlled by the photo-irradiation. We therefore synthesized the caged cytokinin, 2-nitrophenylethyl carbonate linked caged dihydro zeatin that release the zeatin molecule in response to photo-irradiation. However, the caged zeatin with carbonate linker still showed cytokinin activity without photo-irradiation. We then designed and synthesized N9-caged cytokinins (dihedro zeatin and benzyl adenine caged at N9 position in adenine). These N9-caged cytokinins were inactive until photo-irradiation and release active cytokinin when light is irradiated.
