Activation of ascorbate-glutathione cycle inArabidopsis leaves in response to aminotriazole

Journal of Plant Biology, 1998
Aminotriazole(AT)-induced changes in growth, hydrogen peroxide content and activities of H2O2-scavenging antioxidant enzymes were investigated in the growing leaves ofArabidopsis plants (Arabidopsis thaliana cv Columbia). Catalase activity of rosette leaves was reduced by 65% with an application of 0.1 mM AT (a herbicide known as a catalase inhibitor),

Salicylic acid-induced nitric oxide enhances arsenic toxicity tolerance in maize plants by upregulating the ascorbate-glutathione cycle and glyoxalase system.

Journal of Hazardous Materials, 2020
The role of nitric oxide (NO) in salicylic acid (SA)-induced tolerance to arsenic (As) stress in maize plants is not reported in the literature.

Preharvest application of selenite enhances the quality of Chinese flowering cabbage during storage via regulating the ascorbate-glutathione cycle and phenylpropanoid metabolisms.

Food Research International, 2022
Chinese flowering cabbage (Brassica campestris L. ssp. chinensis var. utilis Tsen et Lee) is a candidate of selenium (Se) accumulator, but it is not clear whether and how preharvest Se treatment affects its quality after harvest.

Role of the Ascorbate–Glutathione Cycle in Paraquat Tolerance of Rice

Weed Science, 2013
Out of 1,343 mutant lines of rice mutated by sodium azide from the parental Japonica-type variety ‘Tainung 67’ (TNG67), a paraquat-susceptible line 1192 and a paraquat-tolerant line 72 were selected using whole seedlings at the four-leaf stage and leaf segments at the tillering stage as test materials.

Effect of High-Temperature Stress on Ascorbate–Glutathione Cycle in Maize

Agricultural Research, 2019
High-temperature stress induces cellular changes leading to over-production of highly reactive oxygen species (ROS) which damage macromolecules and cell organelles, eventually resulting in cell death. Antioxidative metabolism in plants comprising of enzymatic and non-enzymatic antioxidants imparts tolerance by scavenging or detoxification of excess ROS.

Regulation of the Ascorbate–Glutathione Cycle in Plants Under Drought Stress

2010
Ascorbate (Asc) and glutathione (GSH) are important molecules functioning in several vital processes in plant cells, including the ascorbate-glutathione cycle. They are involved in basic metabolic reactions normally occurring in plants as well as in those evoked by abiotic or biotic stresses.

Proteomic and activity profiles of ascorbate–glutathione cycle enzymes in germinating barley embryo

Phytochemistry, 2010
Enzymes involved in redox control are important during seed germination and seedling growth. Ascorbate-glutathione cycle enzymes in barley embryo extracts were monitored both by 2D-gel electrophoresis and activity measurements from 4 to 144 h post imbibition (PI). Strikingly different activity profiles were observed.

Ascorbate‐glutathione cycle alleviates low‐temperature‐induced oxidative stress for augmented growth of Nannochloropsis oceanica Rose Bengal mutants

Physiologia Plantarum : An International Journal for Plant Biology
Studying the adaptive mechanisms of algae to abiotic stresses, such as low temperature and high light intensities, can help facilitate large‐scale outdoor production.

Ascorbate-Glutathione Cycle and Biotic Stress Tolerance in Plants

2017
The ascorbate-glutathione cycle (AsA-GSH cycle) is a central pathway of the plant cells linking the H2O2-scavenging activity to redox signalling. Here, we summarize the most recent advances in our understanding of the role of AsA-GSH cycle in plant–pathogen interactions.

Ascorbate–Glutathione Cycle: Controlling the Redox Environment for Drought Tolerance

2016
Drought impact on plants, similar to other abiotic stresses, is accompanied by increased levels of reactive oxygen species (ROS) such as hydrogen peroxide (H2O2), hydroxyl radical (.OH) and superoxide anion (O2−). Survival strategies of plants under stress conditions often involve antioxidant defense activation. The nonenzymatic antioxidants ascorbate (
