Distribution of Dehydroascorbic Acid Reductase in the Wheat Grain [PDF]
Nature, 1964 Hopkins and Morgan1 showed that the juices of cauliflower and cabbage contain an enzyme which catalyses the reduction of dehydroascorbic acid (DHA) by glutathione (GSH). Crook2 determined the properties of this reductase and separated it from the associated ascorbic acid oxidase.

Proteomic insights on root and tuber crops’ response to abiotic stress—A review
Crop Science, Volume 65, Issue 6, November/December 2025.Abstract Root and tuber crops are a good source of food energy on a global scale, particularly in African and Asian nations. Nevertheless, these crops can be susceptible to abiotic stresses such as excessive heat, high salinity, drought, and nutrient deficiencies, which have detrimental effects on the physiological and metabolic processes of the plants,

Andrology, Volume 13, Issue 6, Page 1601-1614, September 2025.Abstract Background Ascorbic acid 2‐glucoside (AA2G) is a stabilized form of ascorbic acid and a potent antioxidant. Ascorbic acid is present in the testes and epididymis and helps maintain the physiological integrity of reproductive organs. Its properties have been utilized to protect spermatozoa of different species from oxidative stress.

Role of antioxidative system during the development and senescence of cucumber fruit
Biologia Plantarum, 2012 The oxidative processes and antioxidative system in cucumber (Cucumis sativus L.) fruit were determined during development and senescence. Four distinct developmental stages could be delineated during fruit maturation: immature (3-8 d after anthesis, DAA)

STUDIES ON DEHYDROASCORBIC ACID REDUCTASE IN ESCHERICHIA COLIK12
THE JOURNAL OF VITAMINOLOGY, 1965 1. The enzymatic reduction of dehydro-L-ascorbic acid in Escherichia coli was reported at the physiological pH range with the assay condition without loss of resulting ascorbic acid.2. The enzyme, dehydroascorbic acid reductase, was partially purified, and some properties were observed. Hydrogen donors, hydrogen acceptors, and cofactor requirement were

Unraveling the functional dynamics of Caenorhabditis elegans stress‐responsive omega class GST‐44
The FEBS Journal, Volume 292, Issue 17, Page 4675-4693, September 2025.Omega‐class glutathione S‐transferases (GSTs) are integral to redox regulation and cellular stress responses. This study characterized GST‐44 in Caenorhabditis elegans, revealing its predominant expression in the intestine and excretory H‐cell, with significant upregulation under various stress conditions.

Physiologia Plantarum, Volume 177, Issue 5, September/October 2025.ABSTRACT Light and inorganic carbon (Ci) drive photosynthesis, which fuels cellular maintenance, energy storage, and growth in photosynthetic organisms. Despite its pivotal role, how primary metabolism adjusts to contrasting light and Ci availability in algae remains elusive.
