Many physiological conditions such as host defense or aging and pathological conditions such as neurodegenerative diseases, and diabetes are associated with the accumulation of high levels of reactive oxygen species and reactive nitrogen species. This generates a condition called oxidative stress. Low levels of reactive oxygen species, however, which are continuously produced during aerobic metabolism, function as important signaling molecules, setting the metabolic pace of cells and regulating processes ranging from gene expression to apoptosis. For this book we would like to recruit the experts in the field of redox chemistry, bioinformatics and proteomics, redox signaling and oxidative stress biology to discuss how organisms achieve the appropriate redox balance, the mechanisms that lead to oxidative stress conditions and the physiological consequences that contribute to aging and disease.

This book summarizes the latest research results on the role of reactive oxygen species (ROS) in plants, particularly in many abiotic stresses, and their regulation. Redox homeostasis refers to maintaining a balance of oxidised and reduced state of biomolecules in a biological system for all-round sustenance. In a living system, redox reactions contribute to the generation of reactive oxygen species (ROS), which act as signalling molecules for developmental as well as stress-response processes in plants. It is presumed that, being sessile and an aerobe requiring oxygen for mitochondrial energy production, as well as producing oxygen during photosynthesis, the redox homeostasis process is more complex and regulated in plants than in animals. Any imbalance in the homeostasis is mainly compensated for by the production of various ROS molecules, which, though they can cause severe oxidative damage in excess, can also ideally act as signalling molecules.

This Special Issue features recent data concerning thioredoxins and glutaredoxins from various biological systems, including bacteria, mammals, and plants. Four of the sixteen articles are review papers that deal with the regulation of development of the effect of hydrogen peroxide and the interactions between oxidants and reductants, the description of methionine sulfoxide reductases, detoxification enzymes that require thioredoxin or glutaredoxin, and the response of plants to cold stress, respectively. This is followed by eleven research articles that focus on a reductant of thioredoxin in bacteria, a thioredoxin reductase, and a variety of plant and bacterial thioredoxins, including the m, f, o, and h isoforms and their targets. Various parameters are studied, including genetic, structural, and physiological properties of these systems. The redox regulation of monodehydroascorbate reductase, aminolevulinic acid dehydratase, and cytosolic isocitrate dehydrogenase could have very important consequences in plant metabolism. Also, the properties of the mitochondrial o-type thioredoxins and their unexpected capacity to bind iron–sulfur center (ISC) structures open new developments concerning the redox mitochondrial function and possibly ISC assembly in mitochondria. The final paper discusses interesting biotechnological applications of thioredoxin for breadmaking.

This book highlights the latest advances made in the niche area of Reactive Oxygen Species and Redox processes in plants. It offers a valuable guide for researchers and students alike, providing insights into sensing, detox scavenging, the role in oxidative deterioration, and signaling associated with redox-regulatory processes in plants. The book also dramatically demonstrates how these amazingly resourceful molecular species and radicals are poised at the core of a sophisticated network of signaling pathways, and act as vital regulators of plants’ cell physiology and cellular responses to the environment. The molecular language associated with ROS-mediated signal transduction, which produces modulations in gene expression that determine plants’ stress acclamatory performance, is also discussed. The book subsequently provides information on current trends in redox proteomics and genomics, which include efforts to gain a fuller understanding of these redox players’ role in cellular processes, and to further the application of this knowledge to technology and agriculture. Given its scope and format, the book offers a valuable asset for students of Plant Sciences, Agriculture, and Molecular Biology, as well as readers engaged in research on and teaching ROS Biology.

With contributions that review research on this topic throughout the world, Oxidative Damage to Plants covers key areas of discovery, from the generation of reactive oxygen species (ROSs), their mechanisms, quenching of these ROSs through enzymatic and non-enzymatic antioxidants, and detailed aspects of such antioxidants as SOD and CAT. Environmental stress is responsible for the generation of oxidative stress, which causes oxidative damage to biomolecules and hence reduces crop yield. To cope up with these problems, scientists have to fully understand the generation of reactive oxygen species, its impact on plants and how plants will be able to withstand these stresses. - Provides invaluable information about the role of antioxidants in alleviating oxidative stress - Examines both the negative effects (senescence, impaired photosynthesis and necrosis) and positive effects (crucial role that superoxide plays against invading microbes) of ROS on plants - Features contributors from a variety of regions globally

Plants depend on physiological mechanisms to combat adverse environmental conditions, such as pathogen attack, wounding, drought, cold, freezing, salt, UV, intense light, heavy metals and SO2. Many of these cause excess production of active oxygen species in plant cells. Plants have evolved complex defense systems against such oxidative stress. The

Redox regulation, like phosphorylation, is a covalent regulatory system that controls many of the normal cellular functions of all living cells and organisms. In addition, it controls how cells respond to stress involving oxidants and free radicals, which underlie many degenerative diseases. This area is undergoing a transition from general knowledge to specific description of the components and mechanisms involved.This invaluable book provides a timely basic description of a field whose relevance to cell biology and degenerative diseases is of the utmost importance. It describes the state of the art, lays the foundations for understanding the reactions involved, and presents the prospects for future developments. It can serve as a basic text for any undergraduate or graduate course that deals with redox regulation, oxidative stress and free radicals under normal and pathological conditions in bacterial, plant and animal cells.
