Respiratory supercomplexes of plant mitochondria: Structure and possible functions

Respiratory supercomplexes of plant mitochondria: Structure and possible functions Over the last few years a vast amount of information has accumulated on the structural organization of mitochondrial electron-transport chain. The respiratory complexes were shown to be organized into sophisticated dynamic structures, so-called supercomplexes and megacomplexes that ensure sustained and effective operation of the respiratory electron-transport chain. This review considers structural and functional features of plant supercomplexes, as well as their possible role in energy-related adaptation of plants to stresses. It is proposed that supercomplexes provide the first-line defense mechanism that protects the electron-transport chain against reactive oxygen species in stressed plants. Subsequent protective responses involve the alternative respiratory pathways, uncoupling mechanisms, and other antioxidant systems. Russian Journal of Plant Physiology Springer Journals
