Presents a unique compilation of information on antioxidants and antioxidant enzymes in plants; Highlights antioxidants and their role in signaling and stress physiology; Is useful to researchers and students specializing in plant enzyme technology
Spectrophotometric assays for antioxidant enzymes in plants
Superoxide dismutase, catalase, ascorbate peroxidase, and glutathione reductase play a vital role in combating oxidative stress. Measuring these enzyme activities spectrophotometrically provides researchers an easy and precise way to study and understand an important part of the defense against oxidative stress.
The effects of exogenously applied antioxidants on plant growth …
2023年4月1日 · Endogenous plant antioxidant systems help modulate ROS signaling and mitigate ROS damage. These systems typically include both chemical reductants and enzymes that can detoxify ROS or regenerate the reductants (Gill and Tuteja 2010).
Mechanisms of Plant Antioxidants Action - PubMed
2020年12月25日 · Antioxidants inhibit or quench free radical reactions mainly based on their reducing capacity or hydrogen atom-donating capacity, their solubility, and chelating properties. Moreover, their ability to modulate key metabolic enzymes and activate/block gene transcription also has remarkable importance.
Reactive Oxygen Species and Antioxidant Enzymes Involved in Plant …
2016年2月17日 · Plants have defense mechanisms against oxidative damage that are activated during stress to regulate toxic levels of ROS. Antioxidant and nonantioxidant systems are involved in ROS detoxification. During the last decades, antioxidant enzymes have been used to develop transgenic plants that have increased tolerance to several stresses.
Signaling Toward Reactive Oxygen Species-Scavenging Enzymes in Plants
2021年2月1日 · Antioxidant enzymes represent a major ROS-scavenging force and are crucial for stress tolerance in plants. Enzymatic antioxidant defense occurs as a series of redox reactions for ROS elimination. Therefore, the deregulation of the antioxidant machinery may lead to the overaccumulation of ROS in plants, with negative consequences both in terms ...
An Introduction to Antioxidants and Their Roles in Plant Stress ...
2017年8月3日 · Antioxidant enzymes – Catalase, superoxide dismutase, peroxidase, glutathione reductase, etc., are major enzymes that help in scavenging ROS. 2. Antioxidant vitamins – Vitamin B, vitamin E and vitamin C are important for metabolic activities that …
Recent progress in enzymatic antioxidant defense system in plants ...
2024年1月1日 · Plants have developed a number of strategies to avert stress-induced oxidative damage, which includes the involvement of an antioxidant defense system consisting of numerous enzymatic and nonenzymatic antioxidant components. In this chapter, we focus only on the enzymatic antioxidant components of plants essential for coping with these challenges.
