lpha -amylase and superoxidedismutase,Abstract
The results presented in this report show real effect of the pH of the incubation medium on the activities of alpha -amylase and superoxidedismutase of wheat aleurone layer. It has been shown that aleurone layer cells really enhance the extracellular medium acidification processes under the action of GA. At the same time, the sensitivity of aleurone layer cells towards GA in respect to both amylase and antioxidant enzymes substantially increases when the pH of incubation medium is neutral. . It has been proposed that to form full cell response only the interaction of GA with its receptor is required to initiate subsequent distal stages of hormonal effect realization.References
