Fig. 3: Mitochondrial complex I capacity was decreased in sop10 mutants.

a Diagram of the mitochondrial electron transport chain. The two black lines represent the limits of the membrane bilayer. NADs are core subunits of mitochondrial complex I encoded by the mitochondrial genome. b In-gel assay of NADH oxidase capacity. The plants were grown at 22 °C. The dihydrolipoamide dehydrogenase activity was used as a loading control. Experiments were repeated three times independently with similar results. Source data for (b) are provided as a Source Data file.
