Dysfunction of the mitochondria inabc1k10amutants under salt stress. (a) Expression of the oxidative stress related genes. Expression ofSOD2,CAT2,AOX1aandAOX1din plants treated with 200 mM NaCl was determined by qRT-PCR. Error bars indicate ± SD (n = 3). Asterisks indicate statistically significant differences with the corresponding wild type (**P < 0.01 and ***P < 0.001,t-test). (b) The abundance of the mitochondrial complexes in wild type and the10amutants. Crude mitochondrial membranes were extracted from 5-day-old seedlings grown on MS medium or MS medium supplemented 100 mM NaCl. The mitochondrial complexes were separated by Blue Native-PAGE and stained with coomassie brilliant blue
