Major reactive oxygen species (ROS)-scavenging/modulating enzymes include the superoxide dismutase (SOD) that dismutates O2 into H2O2, which is followed by the coordinated action of a set of enzymes including catalase (CAT), ascorbate peroxidase (APX), glutathione peroxidase (GPX) and peroxiredoxins (Prx) that remove H2O2. In addition to the ROS scavenging enzymes, a number of other enzymes are found in various subcellular compartments, which are involved in maintaining such redox homeostasis either by directly scavenging particular ROS and ROS-byproducts or by replenishing antioxidants. In that respect, these enzymes can be also considered antioxidants. Such enzymes include monodehydroascorbate reductase (MDAR), dehydroascorbate reductase (DHAR), glutathione reductase (GR), alternative oxidases (AOXs), peroxidases (PODs) and glutathione S-transferases (GSTs). Some non-enzymatic antioxidants, such as ascorbic acid (vitamin C), carotenes (provitamin A), tocopherols (vitamin E), and glutathione (GSH), work in concert with antioxidant enzymes to sustain an intracellular steady-state level of ROS that promotes plant growth, development, cell cycles and hormone signaling, and reinforces the responses to abiotic and biotic environmental stressors. Offering a unique compilation of information on antioxidants and antioxidant enzymes, this is a valuable resource for advanced students and researchers working on plant biochemistry, physiology, biotechnology, and signaling in cell organelles, and those specializing in plant enzyme technology. 000826998 588__ $$aDescription based on online resource; title from digital title page (viewed on April 12, 2018). 000826998 650_0 $$aAntioxidants$$xPhysiological effect. 000826998 650_0 $$aBotanical chemistry. 000826998 650_0 $$aPlants$$xMetabolism. 000826998 650_0 $$aOxidative stress. 000826998 7001_ $$aGupta, Dharmendra Kumar$$c(Phytoremediation researcher),$$eeditor. 000826998 7001_ $$aPalma, José M.,$$eeditor. 000826998 7001_ $$aCorpas, Francisco J.,$$eeditor. 000826998 77608 $$iPrint version: $$z9783319750873 000826998 852__ $$bebk 000826998 85640 $$3SpringerLink$$uhttps://univsouthin.idm.oclc.org/login?url=http://link.springer.com/10.1007/978-3-319-75088-0$$zOnline Access$$91397441.1 000826998 909CO $$ooai:library.usi.edu:826998$$pGLOBAL_SET 000826998 980__ $$aEBOOK 000826998 980__ $$aBIB 000826998 982__ $$aEbook 000826998 983__ $$aOnline 000826998 994__ $$a92$$bISE
