Journal ArticleDOI
ASCORBATE AND GLUTATHIONE: Keeping Active Oxygen Under Control
Graham Noctor,Christine H. Foyer +1 more
TL;DR: A detailed account of current knowledge of the biosynthesis, compartmentation, and transport of these two important antioxidants, with emphasis on the unique insights and advances gained by molecular exploration are provided.
Journal ArticleDOI
Reactive Oxygen Species, Oxidative Damage, and Antioxidative Defense Mechanism in Plants under Stressful Conditions
TL;DR: The generation, sites of production and role of ROS as messenger molecules as well as inducers of oxidative damage are described and the antioxidative defense mechanisms operating in the cells for scavenging of ROS overproduced under various stressful conditions of the environment are described.
Journal ArticleDOI
Ascorbate peroxidase – a hydrogen peroxide-scavenging enzyme in plants
TL;DR: Amino acid sequence and other molecular properties indicate that ascorbate peroxidase resembles cytochrome c peroxIDase from fungi rather than guaiacol per oxidase from plants, and it is proposed that the plant and yeast hydrogen peroxide-scavenging peroxidsases have the same ancestor.

Delayed leaf senescence induces extreme drought tolerance in a flowering plant
Rosa M. Rivero,Mikiko Kojima,Amira Gepstein,Hitoshi Sakakibara,Ron Mittler,Shimon Gepstein,Eduardo Blumwald +6 more
TL;DR: In this article, a transgenic plant expressing an isopentenyltransferase gene driven by a stress-and maturation-induced promoter was used to suppress the senescence of leaves during a long drought period.

Drought Induces Oxidative Stress and Enhances the Activities of Antioxidant Enzymes in Growing Rice Seedlings
TL;DR: In this article, in vitro rice seedlings grown for 10 and 20 days were subjected to in vitro drought stress of −0.5 and −2.0 MPa for 24 hours, an increase in the concentration of superoxide anion (O2), increased level of lipid peroxidation and a decrease of total soluble protein and thiols was observed in stressed seedlings compared to controls.
