Oxygen metabolism coming up ROSes: a holistic view of the redox metabolism of plant cells
A holistic approach to the oxygen metabolism of plant cells requires consideration not only of the underpinning chemistry and of the factors that contribute to and control the production of active forms of oxygen, but also how cells perceive and respond to changes in the abundance of Reactive Oxygen Species (ROS). Formed during the reduction of molecular oxygen or water oxidation, ROS are produced by a variety of enzymes and redox reactions in almost every compartment of the plant cell. However, the accumulation of ROS in any tissue or cellular compartment is tightly
