Response of the ascorbate–glutathione cycle to excess copper in Arabidopsis thaliana (L.)

Plant Science, 2003
Abstract An operation of the ascorbate–glutathione cycle was investigated in leaves of Arabidopsis thaliana treated with excess Cu (0, 5, 25 50 and 100 μM) for 1, 3 and 7 days. After one-day-treatment significant increase of dehydroascorbate reductase (DHAR) activity and decrease of GSH level was found independently on Cu concentration. Activity of

Enzymatic responses of the ascorbate-glutathione cycle to drought in sorghum and sunflower plants

Plant Science, 1996
To determine if responses of H2O2-scavenging enzymes to drought differ in sorghum (Sorghum bicolor (L.) Moench, C4) and sunflower (Helianthus annuus L., C3), we measured activities of the enzymes involved in the ascorbate-glutathione cycle (AGC), ascorbate peroxidase (AP), dehydroascorbate reductase (DR), and monodehydro-ascorbate reductase (MR), as ...

Cadmium-induced oxidative stress and response of the ascorbate–glutathione cycle in Bechmeria nivea (L.) Gaud

Chemosphere, 2007
Bechmeria nivea (L.) Gaud. (ramie) seedlings subjected to a series of cadmium (Cd) concentrations (0, 1, 3 and 7 mg l(-1)) over a 10d period were investigated with regard to the uptake and distribution of Cd, its effect on membrane lipid and chlorophyll synthesis, and response of the ascorbate-glutathione cycle in both leaves and roots.

Nitric oxide alleviates salt-induced stress damage by regulating the ascorbate-glutathione cycle and Na+/K+ homeostasis in Nitraria tangutorum Bobr.

Plant physiology and biochemistry : PPB, 2022
Nitric oxide (NO) is an important signaling molecule involved in mediation of salt stress induced physiological responses in plants. In this study, we investigated the effect of NO on Nitraria tangutorum seedlings exposed to salt stress.

Hydrogen sulfide manages hexavalent chromium toxicity in wheat and rice seedlings: The role of sulfur assimilation and ascorbate-glutathione cycle.

Environmental Pollution, 2022
The role of hydrogen sulfide (H2S) is well known in the regulation of abiotic stress such as toxic heavy metal. However, mechanism(s) lying behind this amelioration are still poorly known.

Function of the ascorbate-glutathione cycle in aged sunflower seeds

Physiologia Plantarum, 1996
The function of the ascorbate‐glutathione (AsA/GSH) cycle was analyzed in seeds of sunflower (Helianthus annuus L. cv. Peredovik) subjected to accelerated ageing at 43°C and 75% relative humidity for 1 to 11 days. The study was performed using dry seeds and seeds hydrated by imbibition in distilled water for 4 h at 25 °C.

The participation of nitric oxide in hydrogen sulphide-mediated chromium tolerance in pepper (Capsicum annuum L) plants by modulating subcellular distribution of chromium and the ascorbate-glutathione cycle.

Environmental Pollution, 2022
The promising response of chromium-stressed (Cr(VI)-S) plants to hydrogen sulphide (H2S) has been observed, but the participation of nitric oxide (NO) synthesis in H2S-induced Cr(VI)-S tolerance in plants remains to be elucidated.
