What is Isotope labeling of plant hormones, Cytokinin, Zeatin, GA, ABA, JA, Brassinolide

.There are six types of Isotope labeling plant hormones, namely growth hormone (auxin), gibberellic acid (GA), cytokinin (CTK), ABA (abscisic acid, ABA), ethylene (ethyne, ETH), and rape factors sterol ( brassinosteroid, BR). They are simple small molecule organic compounds, but their physiological effects is very complex and diverse. For example, from the influence of cell division, elongation, differentiation to affect plant germination, rooting, flowering, seed setting, the gender of the decision to sleep and off. Isotope labeling. Important regulator of plant hormones on plant growth and development of control action. Isotope labeling. Of the chemical structure of the plant hormones have been known, and some have been synthesized, such as indole acetic acid; and some synthetic, such as gibberellin. The gibberellin reagents currently sold on the market preparation from the culture filtrate of Fusarium. These additional plants indoleacetic acid and gibberellic acid, indoleacetic acid and gibberellin plant source is different, so as a plant growth regulator, also known as the exogenous shock of plant
