The Effects of Water Stress on the Growth of Corn and the Activity Dynamics of NADP–Dependent Isocitrate Dehydrogenase Enzyme in the Leaf and Root T issues

Abstract

Developmental dynamics of the NADP-dependent isocitrate dehydrogenase enzyme has been studied (NADP-ICDH, EC 1.1.1.42) as the reducing potential of the cell for the development of corn sprouts through water stress conditions (water shortage and over water stress) which has a great role in forming NADPH pool. It was determined that the activity of NADP-ICDH enzyme increases both in root and leaf tissues significantly for the effects of water stress and over water stress induces the activity of enzyme more sharply than water shortage stress. The activity degree of enzyme in all three variants manifests itself higher in leaf tissues than root tissues. It seems NADP is required for the corn seedlings in order to eliminate stress complications and NADP-ICDH enzyme is directly involved in its synthesis.
