ИЗУЧЕНИЕ ДЕЙСТВИЯ ФИТОГОРМОНОВ НА АКТИВНОСТЬ КСАНТИНДЕГИДРОГЕНАЗЫ В АЛЕЙРОНОВОМ СЛОЕ ЗЕРНА ПШЕНИЦЫ

Abstract

For the first time we showed ROS generating activity of xanthine dehydrogenase in aleuronic layer of wheat grain. According to the data activity this enzyme is under regulation of phytohormones. One of primary effects of GA in aleuronic layer is the activation of xanthine dehydrogenase. The enzyme is always in active form in presence of GA. Action of ABA is directed on slowing down activation effect of GA on early steps.
