Recent advances in understanding of the mitochondrial respiratory machinery of cells are described, including the presence of a classical oxidative phosphorylation system linked to the cytosol by transporters discussed alongside nonphosphorylating bypasses that alter the efficiency of ATP synthesis and play a role in oxidative stress responses in plants.
The Absence of ALTERNATIVE OXIDASE1a in Arabidopsis Results in Acute Sensitivity to Combined Light and Drought Stress[W][OA]
Results indicate that aox1a plants have a greatly altered stress response even when mitochondria or the mitochondrial electron transport chain are not the primary target of the stress and that AOX1a plays a broad role in determining the normal redox balance in the cell.
