Unraveling thioredoxin-linked metabolic processes of cereal starchy endosperm using proteomics [PDF]

, 2003
Application of a thiol-specific probe, monobromobimane, with proteomics and enzyme assays led to the identification of 23 thioredoxin targets in the starchy endosperm of mature wheat seeds (Triticum aestivum cv. Butte), almost all containing at least two

Exogenous salicylic acid enhances wheat drought tolerance by influence on the expression of genes related to ascorbate-glutathione cycle

Biologia Plantarum, 2013
Treatment with 0.5 mM salicylic acid (SA) significantly alleviated growth inhibition induced by drought in wheat seedlings, manifested by less decreassed fresh mass, dry mass, plant height, root length, and less increased lipid peroxidation.

Putrescine improves salt tolerance of wheat seedlings by regulating ascorbate and glutathione metabolism, photosynthetic performance, and ion homeostasis

Plant, Soil and Environment, 2023
To supply more insights into the roles of putrescine (Put) in alleviating salt stress in wheat crops, we explored the effects of Put on ascorbate (ASC) and glutathione metabolism, photosynthetic performance, and ion homeostasis in leaves of salt-stressed

Reduction of Dehydroascorbate to Ascorbate by the Selenoenzyme Thioredoxin Reductase [PDF]

Journal of Biological Chemistry, 1997
Recycling of ascorbate from its oxidized forms is essential to maintain stores of the vitamin in human cells. Whereas reduction of dehydroascorbate to ascorbate is thought to be largely GSH-dependent, we reconsidered the possibility that the selenium-dependent thioredoxin system might contribute to ascorbate regeneration.

Nitric oxide acts downstream of hydrogen peroxide in the regulation of ascorbate and glutathione metabolism by jasmonic acid in Agropyron cristatum leaves

Biologia Plantarum, 2017
The relationship between hydrogen peroxide (H2O2) and nitric oxide (NO) in the regulation of ascorbate and glutathione metabolism by jasmonic acid (JA) in Agropyron cristatum leaves were studied.

A Systems Biology Study in Tomato Fruit Reveals Correlations between the Ascorbate Pool and Genes Involved in Ribosome Biogenesis, Translation, and the Heat-Shock Response

Frontiers in Plant Science, 2018
Changing the balance between ascorbate, monodehydroascorbate, and dehydroascorbate in plant cells by manipulating the activity of enzymes involved in ascorbate synthesis or recycling of oxidized and reduced forms leads to multiple phenotypes.

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.

Over-expression of dehydroascorbate reductase enhances oxidative stress tolerance in tobacco

Electronic Journal of Biotechnology, 2017
Background: Ascorbic acid (Asc) is one of the most abundant antioxidants and it serves as a major contributor to protect plants against oxidative damage. Plants use two enzymes that participate in the metabolic recycling of Asc.

Interaction of triacontanol and arsenic on the ascorbate-glutathione cycle and their effects on the ultrastructure in Coriandrum sativum L. [PDF]

, 2017
Exogenous application of triacontanol (TRIA) has the ability to mitigate the adverse effects of abiotic stresses by modulating a number of physio-biochemical processes in different plants.

Purification and Characterization of Chloroplast Dehydroascorbate Reductase from Spinach Leaves [PDF]

Plant and Cell Physiology, 2000
Green leaves of plants require the high-level activity that can regenerate ascorbate during photosynthesis. One of such enzyme is dehydroascorbate reductase (DHAR), but the molecular and enzymological properties of the enzyme remain to be fully characterized. In this study, we showed that two major DHAR existed in spinach leaves. The two DHARs occupied
