Ammonium nutrition has been suggested to be associated with alterations in the oxidation-reduction state of leaf cells. Herein, we show that ammonium nutrition in Arabidopsis thaliana increases leaf NAD(P)H/NAD(P)(+) ratio, reactive oxygen species content and accumulation of biomolecules oxidized by free radicals. We used the method of rapid fractionation(More)
Reactive oxygen species (ROS) generally regarded as harmful products of oxygenic metabolism causing oxidative stress and cell damage are also important for control and regulation of biological processes. ROS can be generated by various enzymatic activities and removed by an array of ROS-scavenging molecules in the cell. In plants, the generation of ROS(More)
