The impact of oxidative stress on Arabidopsis mitochondria.
Treatment of Arabidopsis cell culture for 16 h with H2O2, menadione or antimycin A induced an oxidative stress decreasing growth rate and increasing DCF fluorescence and lipid peroxidation products.Expand
Organization and regulation of mitochondrial respiration in plants.
Mitochondrial respiration in plants provides energy for biosynthesis, and its balance with photosynthesis determines the rate of plant biomass accumulation. We describe recent advances in ourExpand
Experimental Analysis of the Arabidopsis Mitochondrial Proteome Highlights Signaling and Regulatory Components, Provides Assessment of Targeting Prediction Programs, and Indicates Plant-Specific
A novel insight into Arabidopsis mitochondrial function was revealed from a large experimental proteome derived by liquid chromatography–tandem mass spectrometry. Within the experimental set of 416Expand
Salicylic Acid Is an Uncoupler and Inhibitor of Mitochondrial Electron Transport1
The effect of salicylic acid (SA) on respiration and mitochondrial function was examined in tobacco (Nicotiana tabacum) suspension cell cultures in the range of 0.01 to 5 mm. Cells rapidlyExpand
Molecular Distinction between Alternative Oxidase from Monocots and Dicots1
The alternative oxidase (Aox) is encoded in two discrete gene subfamilies in higher plants. Aox1 is most widely known for its induction by stress stimuli in many tissues and is present in bothExpand
Oxygen affinity terminal oxidases in soybean mitochondria
Respiration of mitochondria isolated from roots and cotyledons of soybean seedlings was monitored over the range of 0-6 μM oxygen, using oxyleghaemoglobin or oxymyoglobin as oxygen sources in aExpand
Stress-induced co-expression of alternative respiratory chain components in Arabidopsis thaliana
Plant mitochondria contain non-phosphorylating bypasses of the respiratory chain, catalysed by the alternative oxidase (AOX) and alternative NADH dehydrogenases (NDH), as well as uncoupling (UCP)Expand

Infection of legume roots or stems with soil bacteria of the Rhizobiaceae results in the formation of nodules that become symbiotic nitrogen-fixing organs. Within the infected cells of these nodules,Expand
Lipoic Acid-Dependent Oxidative Catabolism of α-Keto Acids in Mitochondria Provides Evidence for Branched-Chain Amino Acid Catabolism in Arabidopsis1
Lipoic acid-dependent pathways of α-keto acid oxidation by mitochondria were investigated in pea (Pisum sativum), rice (Oryza sativa), and Arabidopsis. Proteins containing covalently bound lipoicExpand
