Cytosolic carbonic anhydrase in the Gulf toadfish is important for tolerance to hypersalinity.
Carbonic anhydrase (CA) is a ubiquitous enzyme involved in acid-base regulation and osmoregulation. Many studies have demonstrated a role for this enzyme in fish osmoregulation in seawater as well as freshwater. However, to date CA responses of marine fish exposed to salinities exceeding seawater (approximately 35 ppt) have not been examined. Consequently, the aim of the present study was to ex...

متن کاملEnhanced Ascorbic Acid Accumulation through Overexpression of Dehydroascorbate Reductase Confers Tolerance to Methyl Viologen and Salt Stresses in Tomato
As an important antioxidant for plants and humans, L-ascorbic acid (AsA, vitamin C) can scavenge reactive oxygen species (ROS) and can be regenerated from its oxidized form in a reaction catalyzed by dehydroascorbate reductase (DHAR). To analyse the effect of overexpressing DHAR on tomato (Solanum lycopersicum), an expression vector containing potato cytosolic DHAR (DHAR1) or chloroplastic DHAR...
متن کاملDehydroascorbate reductase affects leaf growth, development, and function.
Ascorbic acid (Asc) is a major antioxidant in plants that detoxifies reactive oxygen species (ROS) and maintains photosynthetic function. Expression of dehydroascorbate reductase (DHAR), responsible for regenerating Asc from an oxidized state, regulates the cellular Asc redox state, which in turn affects cell responsiveness and tolerance to environmental ROS. Because of its role in Asc recyclin...
متن کاملMolecular characterization of a dehydroascorbate reductase from Pinus bungeana.
Abstract Dehydroascorbate reductase (DHAR) plays a critical role in the ascorbate-glutathione recycling reaction for most higher plants. To date, studies on DHAR in higher plants have focused largely on Arabidopsis and agricultural plants, and there is virtually no information on the molecular characteristics of DHAR in gymnosperms. The present study reports the cloning and characteristics of a...
