Alteration of mitochondrial protein complexes in relation to metabolic regulation under short-term oxidative stress in Arabidopsis seedlings

► Arabidopsis seedlings were treated with menadione to induce oxidative stress. ► The metabolic responses were examined by proteomic- and metabolomic-approaches. ► Blue-native PAGE was employed to analyse the enzyme complexes in mitochondria. ► The change in spot intensity was closely related to the metabolite profile. ► Some metabolic pathways would be regulated by reassembly of enzyme complexes.
