Effect of Thallium(I) on Growth, Nutrient Absorption, Photosynthetic Pigments, and Antioxidant Response of Dittrichia Plants

Antioxidants, 2023
Dittrichia plants were exposed to thallium (Tl) stress (10, 50, and 100 µM) for 7 days. The Tl toxicity altered the absorption and accumulation of other nutrients.

Post-harvest chitosan treatment suppresses oxidative stress by regulating reactive oxygen species metabolism in wounded apples

Frontiers in Plant Science, 2022
Mechanical wound on fruit triggers the formation of reactive oxygen species (ROS) that weaken cell walls, resulting in post-harvest losses. This mechanism can be controlled by using fruit preservatives to stimulate fruit antioxidant enzyme activities for

Changes in the ascorbate-glutathione system during storage of recalcitrant seeds of Acer saccharinum L.

Acta Societatis Botanicorum Poloniae, 2011
Two seed lots of Acer saccharinum (recalcitrant), with an initial moisture content of 50% and 55%, were stored at +3oC for 6 months. After this time, their viability (measured as germinability) reached 100% and 30%, respectively.

The Antioxidants of Legume Nodule Mitochondria

Molecular Plant-Microbe Interactions, 2001
The mitochondria of legume root nodules are critical to sustain the energy-intensive process of nitrogen fixation. They also generate reactive oxygen species at high rates and thus require the protection of antioxidant enzymes and metabolites.

Heterologous Expression of Dehydroascorbate Reductase from Rice and Its Application to Determination of Dehydroascorbate Concentrations

Journal of Nutritional Science and Vitaminology, 2006
We constructed an expression vector for rice dehydroascorbate reductase (DHAR) (EC 1.8.5.4) with a polyhistidine tag at the amino terminus and introduced the vector into several strains of Escherichia coli. On conventional induction treatment with isopropylthiol-beta-D-galactoside, E. coli harboring rice DHAR cDNA produced doublet polypeptides of about

Cytosolic Dehydroascorbate Reductase is Important for Ozone Tolerance in Arabidopsisthaliana [PDF]

Plant and Cell Physiology, 2006
Dehydroascorbate reductase (DHAR) is a key component of the ascorbate recycling system. Three functional DHAR genes are encoded in the Arabidopsis genome. Ozone exposure increased the expression of the cytosolic DHAR (cytDHAR) gene alone. We characterized an Arabidopsis mutant with a deficient cytDHAR.

Exogenous Allantoin Confers Rapeseed (Brassica campestris) Tolerance to Simulated Drought by Improving Antioxidant Metabolism and Physiology

Antioxidants, 2023
Allantoin is an emerging plant metabolite, but its role in conferring drought-induced oxidative stress is still elusive. Therefore, an experiment was devised to explore the role of allantoin (0.5 and 1.0 mM; foliar spray) in rapeseed (Brassica campestris

Distribution and Functions of Monodehydroascorbate Reductases in Plants: Comprehensive Reverse Genetic Analysis of Arabidopsis thaliana Enzymes

Antioxidants, 2021
Monodehydroascorbate reductase (MDAR) is an enzyme involved in ascorbate recycling. Arabidopsis thaliana has five MDAR genes that encode two cytosolic, one cytosolic/peroxisomal, one peroxisomal membrane-attached, and one chloroplastic/mitochondrial ...
