Peer-reviewed literature demonstrates that in vivo injections of plant growth hormones such as gibberellic acid stimulate cellular and physiological responses in mammals, thereby contradicting the claim that such hormones produce no physiological response.
Plant hormones are major growth regulating hormones (auxins, the gibberellins (GAs), the cytokinins) which are easily available in plant and some plant hormones are also worked as a growth inhibitor such as ethylene, abscisic acid (ABA). These hormones showed an effective result in plant growth, flowering, fruiting, aging, senescence, color enhancement of fruits, prevention or promotion of stem elongation, leafing, leaf fall, shoot, root. These plant hormones are misused for an increase in fruit production, fruit ripening, improving fruit quality traits and overall crop improvement. Therefore, there is a need to check the overdoses of these hormones in fresh and processed food products as there higher doses result in several disorders in humans. There limit of use should be specified and there is a need to develop specific analysis methods to detect their limit in agriculture and food products.
Gibberellic acid, a plant growth hormone, enhances mammalian guanylate cyclase activity.
In vivo injections of gibberellic acid, a potent plant growth hormone, are known to increase the growth of animals as well as plants. Investigation into gibberellic acid's growth promoting mechanism in animals at the cellular level focused on guanylate cyclase (E.C.4.6.1.2.), an enzyme known to be associated with growth. Gibberellic acid enhanced the activity of rat lung guanylate cyclase over a concentration range of .00001 mM to 1 mM with no stimulation being observed at .000001 mM. Varying the concentration of the guanylate cyclase co-factor manganese had no effect on gibberellic acid's enhancement of guanylate cyclase activity. Since human and rat growth hormones also enhance guanylate cyclase activity, it appears that at cellular level the mechanism of action of growth promoting hormones may include a common process that involves enhancement of guanylate cyclase activity.
