Monodehydroascorbate reductase (MDHAR), an important enzyme of the ascorbate-glutathione cycle, is involved in salt tolerance of plants through scavenging of reactive oxygen species (ROS). In this study, a cDNA encoding MDHAR from the mangrove plant Acanthus ebracteatus was introduced into rice to examine its role in salt tolerance.

NADH-monodehydroascorbate reductase in human erythrocyte membranes.
Biochemistry international, 1984Enzymatic activity of NADH-monodehydroascorbate reductase could be observed in red blood cell membranes. This activity was latent in right side out as well as inside out vesicles. Apart from this latency addition of certain detergents led to activation of the enzyme also in open membrane preparations.

Ascorbate is a major antioxidant and radical scavenger in plants. Monodehydroascorbate reductase (MDAR) and dehydroascorbate reductase (DHAR) are two enzymes of the ascorbate-glutathione cycle that maintain ascorbate in its reduced state. MDAR2 (At3g09940) and DHAR5 (At1g19570) expression was upregulated in the roots and shoots of Arabidopsis seedlings

Monodehydroascorbate reductase (MDHAR), a key enzyme to reduce monodehydroascorbate (DHA) to ascorbic acid (AsA), plays an important role in maintaining the level of ascorbic acid in plant cells. It helps to remove reactive oxygen species and regulate cellular redox homeostasis.

Tobacco plants secrete a limited array of proteins (nectarins) into their floral nectar. N-terminal sequencing of the Nectarin II ( NEC2; 35kD) and the Nectarin III ( NEC3; 40kD) proteins revealed that they both share identity with dioscorin, the major soluble protein of yam tubers. These sequences also revealed that NEC2 is a breakdown product of NEC3.

A tomato (Lycopersicon esculentum Mill.) monodehydroascorbate reductase gene (LeMDAR) was isolated. The LeMDAR-green fluorescence protein (GFP) fusion protein was targeted to chloroplast in Arabidopsis mesophyll protoplast. RNA and protein gel blot analyses confirmed that the sense- and antisense- LeMDAR were integrated into the tomato genome. The MDAR

A cDNA encoding a small cysteine-rich protein designated defensin (SPD1) was isolated from sweet potato storage roots. On the basis of the amino acid sequence similarity and conserved residues, it is suggested that SPD1 is a member of the plant defensin family.

Fruit antioxidants are necessary for human health and also have physiological roles in protecting fruit against oxidative stress. Our previous work has shown that monodehydroascorbate reductase (MDHAR) activity was positively correlated with fruit resistance to cold storage in introgression lines of tomato, Solanum lycopersicum.

Effect of high intracellular concentrations of the antioxidants ascorbate and glutathione on the extractable activity of the reducting enzymes dehydroascorbate reductase, monodehydroascorbate reductase, and glutathione reductase were investigated with spinach cells (Spinacia oleracea).
