Exploring Flooding Challenges, Causes, and Mitigation Strategies in Rice

International Journal of Genomics, Volume 2026, Issue 1, 2026.
Flooding is a dominant constraint to rice production in lowland and floodplain ecosystems, where stress intensity, timing, and duration vary widely across agroecological zones. This review synthesizes current knowledge on flooding typologies affecting rice, including anaerobic germination failure, flash flooding, stagnant flooding, and deep‐water ...

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

Dehydroascorbate-reducing proteins in maize are induced by the ascorbate biosynthesis inhibitor lycorine

, 1998
Dehydroascorbate (DHA) reductase (glutathione: dehydroascorbate oxidoreductase, EC 1.8.5.1) has been generally considered aspecific enzyme of the ascorbate-glutathione cycle. However, at least four distinct proteins can catalyze in vitro both glutathione-

Duodenal ascorbate and ferric reductase in human iron deficiency1–3

, 2005
Background: The first step in iron absorption requires the reduction of ferric iron to ferrous iron, a change that is catalyzed by duodenal ferric redUCtase.

Ex vitro acclimatization of plantain plantlets micropropagated in temporary immersion bioreactor

Biologia Plantarum, 2010
Plantain (Musa ABB CEMSA 3/4) plantlets were micropropagated in temporary immersion bioreactors (TIB) or in gelled medium (GM). After ex vitro transfer ROS accumulation was determined by infiltrating leaves with nitroblue tetrazolium (NBT) and 3,3 ...

Lanthanum improves the cadmium tolerance of Zea mays seedlings by the regulation of ascorbate and glutathione metabolism

Biologia Plantarum, 2017
The effect of lanthanum on the metabolism of ascorbate (AsA) and glutathione (GSH) in the leaves of maize seedlings under cadmium stress was investigated.

Modulation of Dcytb (Cybrd 1) expression and function by iron, dehydroascorbate and Hif-2α in cultured cells

, 2014
BACKGROUND:Duodenal cytochrome b (Dcytb) is a mammalian plasma ferric reductase enzyme that catalyses the reduction of ferric to ferrous ion in the process of iron absorption.

Nitric oxide is involved in the regulation of ascorbate and glutathione metabolism in Agropyron cristatum leaves under water stress

Biologia Plantarum, 2012
This study investigated the regulation of ascorbate and glutathione metabolism by nitric oxide in Agropyron cristatum leaves under water stress. The activities of ascorbate peroxidase (APX), glutathione reductase (GR), monodehydroascorbate reductase ...

Arabidopsis dehydroascorbate reductase 1 and 2 modulate redox states of ascorbate-glutathione cycle in the cytosol in response to photooxidative stress

, 2017
Ascorbate and glutathione are indispensable cellular redox buffers and allow plants to acclimate stressful conditions. Arabidopsis contains three functional dehydroascorbate reductases (DHAR1-3), which catalyzes the conversion of dehydroascorbate into ...
