Endophytic fungus Serendipita indica accelerates ascorbate-glutathione cycle of white clover in response to water stress

Frontiers in Microbiology, 2022
Ascorbate-glutathione cycle is an important pathway for plants to scavenge reactive oxygen species (ROS) under environmental stress conditions. The objective of this study was to investigate the effects of the endophytic fungus Serendipita indica on ...

Effect of arsenic-phosphorus interaction on arsenic-induced oxidative stress in chickpea plants [PDF]

, 2009
Arsenic-induced oxidative stress in chickpea was investigated under glasshouse conditions in response to application of arsenic and phosphorus. Three levels of arsenic (0, 30 and 60 mg kg−1) and four levels of P (50, 100, 200, and 400 mg kg−1) were ...

Inactivation Mechanism of Ascorbate Peroxidase at Low Concentrations of Ascorbate; Hydrogen Peroxide Decomposes Compound I of Ascorbate Peroxidase [PDF]

Plant and Cell Physiology, 1996
One of the characteristic properties of ascorbate peroxidase (APX), which distinguishes it from guaiacol peroxidase, Cyt c peroxidase and glutathione peroxidase, is the rapid inactivation of the enzyme under conditions where an electron donor is absent. When thylakoid-bound APX (tAPX) in 100 f/M ascorbate was diluted 500-fold with an ascorbate-depleted

Existing antioxidant levels are more important in acclimation to supplemental UV-B irradiation than inducible ones: Studies with high light pretreated tobacco leaves [PDF]

, 2012
Greenhouse grown tobacco plants were exposed to supplemental ultraviolet irradiation (280-400 nm, UV-B centered) for 6 days and changes in their photosynthesis (gas exchange and electron transport) and general and specific antioxidant activities were ...

The Antioxidants of Legume Nodule Mitochondria

Molecular Plant-Microbe Interactions, 2001
The mitochondria of legume root nodules are critical to sustain the energy-intensive process of nitrogen fixation. They also generate reactive oxygen species at high rates and thus require the protection of antioxidant enzymes and metabolites.
