1. Hydrogen Peroxide is Scavenged by Ascorbate-specific Peroxidase in Spinach ChloroplastsPlant and Cell Physiology · 1981 · 10,808 citations

   Abstract Intact spinach chloroplasts scavenge hydrogen peroxide with a peroxidase that uses a photoreductant as the electron donor, but the activity of ruptured chloroplasts is very low [Nakano and Asada (1980) Plant & Cell Physiol. 21 : 1295]. Ruptured spinach…

2. THE WATER-WATER CYCLE IN CHLOROPLASTS: Scavenging of Active Oxygens and Dissipation of Excess PhotonsAnnual Review of Plant Physiology and Plant Molecular Biology · 1999 · 4,103 citations

   Photoreduction of dioxygen in photosystem I (PSI) of chloroplasts generates superoxide radicals as the primary product. In intact chloroplasts, the superoxide and the hydrogen peroxide produced via the disproportionation of superoxide are so rapidly scavenged at the site of their…

3. Production and Scavenging of Reactive Oxygen Species in Chloroplasts and Their FunctionsPLANT PHYSIOLOGY · 2006 · 2,773 citations

   The reaction centers of PSI and PSII in chloroplast thylakoids are the major generation site of reactive oxygen species (ROS). Photoreduction of oxygen to hydrogen peroxide (H2O2) in PSI was discovered over 50 years ago by Mehler (1951). Subsequently, the…
