In living cells, reactive oxygen species (ROS) play a key role in signaling but these compounds can also damage macromolecules. As in other compartments, the mitochondrial ROS concentrations need to be tightly controlled. Plant mitochondria contain several antioxidant systems that are not only able to scavenge ROS and limit their production but also to repair damages to macromolecules and possibly to serve as redox sensors. They comprise ascorbate- and glutathione-dependent pathways as well as… Expand
Reactive oxygen species and nitric oxide in plant mitochondria: origin and redundant regulatory systems.
TLDR
The involvement of mitochondria-localized enzymes responsible for arginine catabolism, arginase and ornithine aminotransferase has been shown in the regulation of NO efflux, providing the regulatory mechanism for redox homeostasis and specific ROS/NO signaling. Expand

Integrative role of plant mitochondria facing oxidative stress: The case of ozone.
TLDR
An overview of the mitochondrial fate in three steps is proposed, starting with the initial responses of the mitochondria for alleviating the overproduction of ROS by the enhancement of existing antioxidant metabolism and adjustments of the electron transport chain, followed by an accelerated senescence initiated by mitochondrial membrane permeability and leading to programmed cell death.
