THE ENERGETIC FUNCTIONS OF PLANT MITOCHONDRIA UNDER STRESS

Abstract

This article reviews the involvement of the mitochondrial systems, which maintain the balance of cell energy at different stress conditions. It is shown the functioning of the alternative oxidase, free fatty acids, uncoupling proteins, the rotenone-insensitive NAD(P)H dehydrogenases, the ADP/ATP-antiporter, the permeability transition pore and ATP-sensitive potassium channel (К+ATP). It is discussed data about physiological role of these systems in plant cell.
