Gasotransmitters Signaling In Plants Under Challenging Environment

Abiotic stressors, such as drought, extreme temperatures, heavy metals, or high salinity, are causing huge crop losses worldwide. These abiotic stressors are expected to become more extreme, less predictable, and more widespread in the near future. The harm of abiotic stresses includes the disruption of cellular redox homeostasis, reactive oxygen species (ROS) production, and oxidative stress in the plant. Plants have different mechanisms to fight stress, and these mechanisms are responsible for maintaining the required homeostasis in plants. Research on gasotransmitters is rapidly expanding and knowledge regarding the potential of gasotransmitters in biology and medicine is accumulating. Over the past few decades, the roles of these signaling molecules, especially NO and H2S, have been extensively studied for their application in plants. Recently, the emissions of endogenous gasotransmitters in plants have been widely studied and analyzed, thereby providing information to facilitate our understanding of new gasotransmitters signaling pathways. Given the multidimensional role of these signaling molecules, research over the past decades in mitigating abiotic stresses in plant biology and from an agriculture point of view, we intend to bring forth a comprehensive volume “Gasotransmitters Signaling in Plants under Challenging Environment". We are hopeful that this comprehensive volume will furnish the requisite of all those who are working or have an interest in the proposed topic

This book deals with the gasotransmitters signaling in redox reactions and homeostasis for the adaptation of plants to unfavorable abiotic stress environments. There are lots of interesting chapters in this book that cover both research and educational objectives. This book serves as a reference illustrated book for all who are interested in the regulation of gasotransmitters and redox homeostasis in agriculture. Maintenance of redox homeostasis strengthens the potentiality of plants to resist abiotic stress conditions through the enhanced antioxidant system and the subsequent impact on other signaling molecules. The book presents novel outcomes and implications in plant biology concerning the study of different types of gasotransmitters signaling such as nitric oxide (NO), ethylene, hydrogen sulfide (H2S), etc. under diverse abiotic stresses in one place. The chapters of the book discuss the recent progress and current perspectives on the role of gasotransmitters relevance to plant functions and adaptations to abiotic stresses, the influence of gasotransmitters on the physiology of plants with respect to abiotic stress tolerance, gasotransmitters and omics for abiotic stress tolerance, advancement in the biology of gasotransmitters in regulating salinity and drought stress response in plants, new insights of gasotransmitters and cellular redox homeostasis in plants and the chapter also deliberate the emerging role of gasotransmitters in regulating redox homeostasis for plant stress management. This book is the first comprehensive book covering all aspects and advancements in the biology of gasotransmitters in redox homeostasis conferring different abiotic stress tolerance, from which readers from all backgrounds can get benefitted. This book will appeal to researchers, students, scientific societies, agriculturists, etc.

This book describes the three gasotransmitters nitric oxide (NO), hydrogen sulphide (H2S) and carbon monoxide (CO) and their function as intracellular signalling molecules in plants. Common properties are shared by NO, H2S and CO: they are beneficial at low concentrations but hazardous in higher amounts; they are small molecules of gas; they can freely cross cell membranes; their effects do not rely on receptors; they are generated enzymatically and their production is regulated; their functions can be mimicked by exogenous application; and their cellular effects may or may not be mediated by second messengers, but have specific cellular and molecular targets. In plants, many aspects of the biology of gasotransmitters remain completely unknown and generate intriguing questions, which will be discussed in this book.

This book focuses on the role of hydrogen sulfide in the protection of plants against abiotic stresses and abiotic stress-induced complications by the way of converging advanced key methods of proteomics, genomics, and metabolomics. It provides an update on the biosynthesis, signaling, and mechanism of action of hydrogen sulfide in combating abiotic stresses in plants. Also, special emphasis is given to the interaction of hydrogen sulfide with other signaling molecules (such as nitric oxide, carbon monoxide, hydrogen peroxide etc.), phytohormones, mineral nutrients, ions, and ion channels in plants. This work, uniquely, covers key aspects of hydrogen sulfide signaling in relation to abiotic stresses in plants, including programmed cell death, stomatal movement, and fruit ripening.

Gasotransmitters-principally nitric oxide (NO), carbon monoxide (CO), and hydrogen sulfide (H2S)-are endogenous signaling molecules that play a significant role in the biomedical, clinical, and health sciences, as well as in population health studies. In Signal Transduction and the Gasotransmitters: NO, CO, and H2S in Biology and Medicine, a panel of distinguished researchers and clinicians review the biological and biomedical aspects of gasotransmitters, emphasizing their signaling transduction mechanisms in general, and ion channel regulation in particular. The authors discuss the endogeneous metabolism and regulation of gasotransmitters, their toxicological profiles and biological actions, and their interactions in terms of their production and effects. The physiological roles of NO, CO, and H2S in the regulation of the cardiovascular, neuronal, and gastrointestinal systems, as well as of cell metabolism, are also reviewed, along with the interaction of the gastrotransmitters with KATP,KCa voltage-gated Ca2+, voltage-gated Na+, and cyclic nucleotide-gated ion channels. Included in the array of different mechanisms for the interaction of NO, CO, and H2S are channel phosphorylation, S-nitrosylation, carboxylation, sulfuration, and altered cellular redox status. The authors also offer guidance and suggestions for exploring and further characterizing other still unknown gasotransmitters. Authoritative and comprehensive, Signal Transduction and the Gasotransmitters: NO, CO, and H2S in Biology and Medicine offers clinical scientists and physicians not only a deeper understanding, but also a cutting-edge review, of the critically important field of gasotransmitter biology and medicine.

Plant Signaling Molecule: Role and Regulation under Stressful Environments explores tolerance mechanisms mediated by signaling molecules in plants for achieving sustainability under changing environmental conditions. Including a wide range of potential molecules, from primary to secondary metabolites, the book presents the status and future prospects of the role and regulation of signaling molecules at physiological, biochemical, molecular and structural level under abiotic stress tolerance. This book is designed to enhance the mechanistic understanding of signaling molecules and will be an important resource for plant biologists in developing stress tolerant crops to achieve sustainability under changing environmental conditions. Focuses on plant biology under stress conditions Provides a compendium of knowledge related to plant adaptation, physiology, biochemistry and molecular responses Identifies treatments that enhance plant tolerance to abiotic stresses Illustrates specific physiological pathways that are considered key points for plant adaptation or tolerance to abiotic stresses

​This book aims to emphasize on basic concepts of plant growth, acclimation, and their adaptation to environment in changing conditions. The book will provide an updated perspective on the physical/mechanical stress, including biotic and abiotic stress, and induced responses in higher plants. This volume will also include a view of the stress recognition by plants and the cell signaling events triggered as a consequence, and will also address an appraisal of the plant oxidative stress metabolism under those circumstances. The book will explore how soil minerals and microbes are affecting plant growth, including elicitors and novel compounds which stimulate plant growth and the defence mechanisms issued by plants. This volume will also cover an overview on the enzymes which may regulate plant growth, as well as the evidences of the involvement of phytohormones and other signalling molecules in plant growth.
