植物ホルモンとバイオサイエンス

抄録

Plant hormones are very important bio-active compounds which regulate the physiology of higher plants. There are five kinds of known plant hormones, auxin, gibberellin, cytokinin, abscisic acid and ethylene. Besides, there are some other plant hormone-like substances as brassinolide, polyamines and unknown flower-inducing substances. The studies of plant hormones concerning activity, practical use, fluctuation of endogenous level in intact plants, biosynthesis and structure-activity relationship are explained. The organic syntheses in these studies are important especially in production of plant hormones and their related compounds enough for their application test in the agricultural field, and various kinds of derivatization of plant hormones for the investigation of action mechanism and for the modern analysis methods with highest reliability and sensitivity. Some other importance of organic synthesis in plant hormone research is discussed.
