Ascorbic acid (AsA), vitamin C, is one of the most abundant water-soluble antioxidant in plants and animals. In plants AsA serves as a major redox buffer and regulates various physiological processes controlling growth, development, and stress tolerance. Recent studies on AsA homeostasis have broadened our understanding of these physiological events. At the mechanistic level, AsA has been shown to participate in numerous metabolic and cell signaling processes, and the dynamic relationship between AsA and reactive oxygen species (ROS) has been well documented. Being a major component of the ascorbate-glutathione (AsA-GSH) cycle, AsA helps to modulate oxidative stress in plants by controlling ROS detoxification alone and in co-operation with glutathione. In contrast to the single pathway responsible for AsA biosynthesis in animals, plants utilize multiple pathways to synthesize AsA, perhaps reflecting the importance of this molecule to plant health. Any fluctuations, increases or decreases, in cellular AsA levels can have profound effects on plant growth and development, as AsA is associated with the regulation of the cell cycle, redox signaling, enzyme function and defense gene expression. Although there has been significant progress made investigating the multiple roles AsA plays in stress tolerance, many aspects of AsA-mediated physiological responses require additional research if AsA metabolism is to be manipulated to enhance stress-tolerance. This book summarizes the roles of AsA that are directly or indirectly involved in the metabolic processes and physiological functions of plants. Key topics include AsA biosynthesis and metabolism, compartmentation and transport, AsA-mediated ROS detoxification, as well as AsA signaling functions in plant growth, development and responses to environmental stresses. The main objective of this volume is therefore to supply comprehensive and up-to-date information for students, scholars and scientists interested in or currentlyengaged in AsA research.

Mohammad Anwar Hossain is a professor in the Department of Genetics and Plant Breeding, Bangladesh Agricultural University, Mymensingh-2202, Bangladesh. He received his B.Sc. in agriculture and M.S. in genetics and plant breeding from Bangladesh Agricultural University, Bangladesh. He also received an M.S. in agriculture from Kagawa University, Japan, in 2008 and a Ph.D. in abiotic stress physiology and molecular biology from Ehime University, Japan, in 2011 through Monbukagakusho Scholarship. As a JSPS postdoctoral researcher, he has worked on isolating low-phosphorus stress-tolerant genes from rice at the University of Tokyo, Japan, in 2015-2017. His current research interests include the isolation and characterization of abiotic stressresponsive genes and proteins; physiological and molecular mechanisms of abiotic stress response and tolerance with special reference to oxidative stress, antioxidants and methylglyoxal metabolism and signalling; and generation of stress-tolerant and nutrient-efficient plants through breeding and biotechnology and cross stress tolerance in plants. He has over 50 peer-reviewed publications and has edited 7 books, including this one, published by CRC Press, Springer, and Elsevier. Sergi Munné-Bosch is a full professor in the Department of Evolutionary Biology, Ecology and Environmental Sciences, University of Barcelona, Spain. He received his B.Sc. in biology and his Ph.D. in plant biology from the University of Barcelona. His research interests include antioxidants, stress and senescence in plants, including research not only in plant physiology but also in plant ecophysiology and agrifood biotechnology. Main interests include the biosynthesis and function of antioxidant vitamins, plant hormones and secondary metabolites, as well as seed dormancy and germination, leaf, flower and whole-plant senescence and fruit ripening. He is also interested in plant responses to drought and adaptation to extreme temperatures, as well as the ecophysiology of invasive plants. He has co-authored 180 peerreviewed SCI-indexed journal articles, 17 book chapters and 3 books. He is editor-in-chief of the journal Environmental and Experimental Botany from Elsevier.
