Polyamine and nitric oxide crosstalk: Antagonistic effects on cadmium toxicity in mung bean plants through upregulating the metal detoxification, antioxidant defense and methylglyoxal detoxification systems.
Japan. In Ecotoxicol Environ Saf, Feb 2016
Put and/or SNP reduced Cd uptake, increasd phytochelatin (PC) content, reduced oxidative damage enhancing non-enzymatic antioxidants (AsA and GSH) and activities of enzymes [superoxide dismutase (SOD), catalase (CAT), ascorbate peroxidase (APX), dehydroascorbate reductase (DHAR), glutathione reductase (GR), glutathione S-transferase (GST), and glutathione peroxidase (GPX)].
Stevioside prevents oxidative stress in wheat seedlings.
Kazan', Russia. In Dokl Biol Sci, Nov 2015
Stevioside has been demonstrated to cause a decrease in the malondialdehyde formation rate, an increase in the activities of antioxidant enzymes (peroxidase and ascorbate peroxidase), and the accumulation of proline and carotenoids.
Resurrection plants of the genus Ramonda: prospective survival strategies - unlock further capacity of adaptation, or embark on the path of evolution?
Belgrade, Serbia. In Front Plant Sci, 2014
Dehydration induces activation of antioxidative enzymes (ascorbate peroxidase, glutathione reductase, polyphenol oxidase), increase in amounts of AsA and GSH, phenolic acids, dehydrins, sucrose, and inorganic ions.
Separate and combined responses to water deficit and UV-B radiation.
Poznań, Poland. In Plant Sci, 2013
The coordinated increased activity of the enzymatic antioxidant defence system such as up-regulation of superoxide dismutase, catalase, guaiacol peroxidase, ascorbate peroxidase and glutathione reductase is an important mechanism of tolerance to water deficit and UV-B radiation.
Functional roles of flavonoids in photoprotection: new evidence, lessons from the past.
Sesto Fiorentino, Italy. In Plant Physiol Biochem, 2013
We also draw a picture in which vacuolar flavonoids in conjunction with peroxidases and ascorbic acid constitute a secondary antioxidant system aimed at detoxifying H2O2, which may diffuse out of the chloroplast at considerable rates and enter the vacuole following excess light stress-induced depletion of ascorbate peroxidase.
Antioxidant Defenses in Plants with Attention to Prunus and Citrus spp.
Florence, Italy. In Antioxidants (basel), 2012
Biochemical and molecular features of the antioxidant enzymes superoxide dismutase (SOD), catalase (CAT), and ascorbate peroxidase (APX) are discussed because they play crucial roles in scavenging ROS in the different cell compartments and in response to stress conditions.
Antioxidant responses to drought in sunflower and sorghum seedlings.
Manhattan, United States. In New Phytol, 1996
Levels of leaf enzymatic antioxidants (ascorbate peroxidase, catalase, guaiacol peroxidase, dehydroascorbate reductase, monodehydroascorbate reductase, glutathione reductase and superoxide dismutase), nonenzymatic antioxidants (ascorbate, glutathione and carotenoids) and stress parameters (Chl and malondialdehyde [MDA]) were determined.
