What Do the Plant Mitochondrial Antioxidant and Redox Systems Have to Say Under Salinity, Drought, plant cells, including superoxide (O..) and H.O.. In addition to ROS, there are compelling indications that nitric oxide (NO) can be generated in this organelle by both reductive and oxidative pathways. ROS and reactive nitrogen species (RNS) play a key role in signaling but they can also be delete

Redox Regulation and Antioxidant Defence During Abiotic Stress: What Have We Learned from , and Itsin the forthcoming future due to global climate change. . is the model organism for plant science since the early 1990s, and its genome has been known for more than a decade. Studies conducted with . created a foundation that could be transferred and used in its close relatives to similarity of gene

ROS Signaling: Relevance with Site of Production and Metabolism of ROS,volved antioxidant system (antioxidant enzymes and antioxidant molecules) to protect the cell components from oxidative threat. Usually cells accumulate ROS to a fatal level due to imbalance between generation and scavenging under stress or pathogenic attack. Recent observations led to an idea of in

Heavy Metal-Induced Oxidative Stress in Plants: Response of the Antioxidative System,evels of HMs are extremely toxic since they may act in several different modes: by the direct inhibition of plant growth and biosynthetic pathways or through the production of reactive oxygen species (ROS). Certain metals generate ROS due to their involvement in redox reactions like Fenton and/or Ha

Arsenic and Chromium-Induced Oxidative Stress in Metal Accumulator and Non-accumulator Plants and Dnd deleterious effects on the environment. Following uptake by plants, As and Cr generate reactive oxygen species (ROS) and induce oxidative stress, which exerts negative effects on biochemical, molecular, and cellular levels that hinder plant growth and development. When the stressor level reaches

General Roles of Phytochelatins and Other Peptides in Plant Defense Mechanisms Against Oxidative Stynthesized from the precursor glutathione (a reduced form, GSH) by the activity of phytochelatin synthase (PCS). The biosynthesis is stimulated by several heavy metals (HMs), especially Cd and metalloid As. PCs can bind to various HMs like Cd, As, Cu, Pb, Zn, and Ag, via their sulfhydryl (–SH) and c

Role of Polyphenols as Antioxidants in Native Species from Argentina Under Drought and Salinizationina. These plants have developed different strategies to avoid or tolerate the lack of water and/or the excess of toxic ions during their development. As drought and salt stress lead to increased production of reactive oxygen species (ROS) in plant cells, halophytic and xerophytic species have the a
