Molecular cloning and characterization of a rice dehydroascorbate reductase [PDF]
Plant dehydroascorbate reductase (DHAR), which re‐reduces oxidized ascorbate to maintain an appropriate level of ascorbate, is very important, but no gene or cDNA for plant DHAR has been cloned yet. Here, we describe a cDNA for a rice glutathione‐dependent DHAR (designated DHAR1). A recombinant Dhar1p produced in Escherichia coli was functional.

Dehydroascorbate Reductase Affects Non-photochemical Quenching and Photosynthetic Performance [PDF]
Ascorbic acid (Asc) is a major antioxidant involved in photoprotection and photosynthetic function in plants. Dehydroascorbate reductase (DHAR) catalyzes the regeneration of Asc from its oxidized state and serves as an important regulator of Asc recycling.

Noninvasive in vivo imaging of diabetes-induced renal oxidative stress and response to therapy using hyperpolarized 13C dehydroascorbate magnetic resonance. [PDF]
Oxidative stress has been proposed to be a unifying cause for diabetic nephropathy and a target for novel therapies. Here we apply a new endogenous reduction-oxidation (redox) sensor, hyperpolarized (HP) (13)C dehydroascorbate (DHA), in conjunction with ...

Cloning and Characterization of a Biotic-Stress-Inducible Glutathione Transferase from Phaseolus vulgaris [PDF]
Glutathione transferases (GSTs, EC 2.5.1.18) are ubiquitous proteins in plants that play important roles in stress tolerance and in the detoxification of toxic chemicals and metabolites.

Purification and Characterization of Dehydroascorbate Reductase from Rice [PDF]
Dehydroascorbate reductase (DHAR; EC 1.8.5.1) is an enzyme that is critical for maintenance of an appropriate level of ascorbate in plant cells. This report describes the purification and characterization of a GSH-dependent DHAR from rice (Oryza sativa) bran and is the first, to our knowledge, of such an analysis of DHAR from a monocot.
