This book provides an up-to-date overview of redox signaling in plant cells and its key role in responses to different stresses. The chapters, which are original works or reviews, focus on redox signaling states; cellular tolerance under different biotic and abiotic stresses; cellular redox homeostasis as a central modulator; redox homeostasis and reactive oxygen species (ROS); redox balance in chloroplasts and mitochondria; oxidative stress and its role in peroxisome homeostasis; glutathione-related enzyme systems and metabolism under metal stress; and abiotic stress-induced redox changes and programmed cell death. The book is an invaluable source of information for plant scientists and students interested in redox state chemistry and cellular tolerance in plants.

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

This detailed volume presents a wide range of techniques for plant mitochondrial analysis, ranging from tried-and-tested work horse techniques to the latest innovations. Within its pages, it explores subjects such as affinity-based isolation of mitochondria with magnetic beads, mitochondrial quality assessment protocols, measurement of uptake and release of specific metabolites, mitochondrial protein identification and visualization, as well as gene splicing and editing, and much more. Written for the highly successful Methods in Molecular Biology series, chapters include introductions to their respective topics, lists of the necessary materials and reagents, step-by-step, readily reproducible laboratory protocols, and tips on troubleshooting and avoiding known pitfalls. Authoritative and practical, Plant Mitochondria: Methods and Protocols provides a highly useful set of methodologies for the plant mitochondrial community to help discover more interesting aspects of plant mitochondria in the years to come.

Molecular Biology of Plants presents the formal scientific presentations delivered on the symposium on plant molecular biology, held at the University of Minnesota in 1976. The topics in this book are organized around the central dogma of molecular biology. Section I describes the organization and replication of DNA in plant chromosomes, including chloroplast genomes; Section II discusses molecular aspects of transcription and translation, ribosomal RNA gene systems and hormonal control of protein synthesis. Section III examines plant viruses and bacterial agents, in particular the crown gall system, viroids, and the replication of plant RNA viruses. Each of these specific topics contributes to an integrated knowledge of plant molecular biology. The book will be of interest to geneticists, cell biologists, plant breeders, plant physiologists, plant pathologists, and biochemists.

In the two decades since the last comprehensive work on plant peroxisomes appeared, the scientific approaches employed in the study of plant biology have changed beyond all recognition. The accelerating pace of plant research in the post-genomic era is leading us to appreciate that peroxisomes have many important roles in plant cells, including reserve mobilisation, nitrogen assimilation, defence against stress, and metabolism of plant hormones, which are vital for productivity and normal plant development. Many plant scientists are finding, and will no doubt continue to find, that their own area of research is connected in some way to peroxisomes. Written by the leading experts in the field, this book surveys peroxisomal metabolic pathways, protein targeting and biogenesis of the organelle and prospects for the manipulation of peroxisomal function for biotechnological purposes. It aims to draw together the current state of the art as a convenient starting point for anyone, student or researcher, who wishes to know about plant peroxisomes.

Reviews of Environmental Contamination and Toxicology attempts to provide concise, critical reviews of timely advances, philosophy and significant areas of accomplished or needed endeavor in the total field of xenobiotics, in any segment of the environment, as well as toxicological implications.

The Role of Growth Regulators and Phytohormones in Overcoming Environmental Stress is a comprehensive resource on all major PGRs. These include auxins, cytokinins, jasmonates, polyammines, plant growth promoting rhizobacteria (PGPR), and more. In the last two decades, researchers have explored a lot about the roles of plant growth regulators (PGRs) in boosting the resistance of plants under stress conditions. These PGRs acts as stimulators for various physiological processes by regulating key cell signaling pathways. This title is an essential read for any scientist wanting to understand the latest advances in combatting abiotic stresses using plant growth regulators.In the present era, plants are facing a lot of challenges during their lifecycle, including growth declines due to abiotic stress. The main abiotic stresses threatening plants are water scarcity, salinity, extreme temperatures, heavy metals and pesticides. These stresses directly or indirectly cause toxicity to plants, causing hindrance to their growth and development, and ultimately reduce plant productivity. - Provides the latest research on all major Plant Growth Regulators (PGRs) - Focuses on the mechanistic approaches of the physiological and molecular actions of PGRs - Highlights crosstalk between PGRs and phytohormones

Plants, unlike animals, are sessile. This demands that adverse changes in their environment are quickly recognized, distinguished and responded to with suitable reactions. Drought, heat, cold and salinity are among the major abiotic stresses that adversely affect plant growth and productivity. In general, abiotic stress often causes a series of morphological, physiological, biochemical and molecular changes that unfavorably affect plant growth, development and productivity. Drought, salinity, extreme temperatures (cold and heat) and oxidative stress are often interrelated; these conditions singularly or in combination induce cellular damage. To cope with abiotic stresses, of paramount significance is to understand plant responses to abiotic stresses that disturb the homeostatic equilibrium at cellular and molecular level in order to identify a common mechanism for multiple stress tolerance. This multi authored edited compilation attempts to put forth an all-inclusive biochemical and molecular picture in a systems approach wherein mechanism and adaptation aspects of abiotic stress are dealt with. The chief objective of the book hence is to deliver state of the art information for comprehending the effects of abiotic stress in plants at the cellular level.

The entire range of the developmental process in plants is regulated by a shift in the hormonal concentration, tissue sensitivity and their interaction with the factors operating around the plants. Phytohormones play a crucial role in regulating the direction of plant in a coordinated fashion in association with metabolism that provides energy and the building blocks to generate the form that we recognize as a plant. Out of the recognized hormones, attention has largely been focused on Auxins, Gibberellins, Cytokinins, Abscisic acid, Ethylene and more recently on Brassinosteroids. In this book we are providing the information about a brassinosteroids that again confirm its status as phytohormones because it has significant impact on various aspects of the plant life and its ubiquitous distribution throughout the plant kingdom. Brassinosteroids are generating a significant impact on plant growth and development, photosynthesis, transpiration, ion uptake and transport, induces specific changes in leaf anatomy and chloroplast structure. This book is not an encyclopedia of reviews but includes a selected collection of newly written, integrated, illustrated reviews describing our knowledge of brassinosteroids. The aim of this book is to tell all about brassinosteroids, by the present time. The various chapters incorporate both theoretical and practical aspects and may serve as baseline information for future researches through which significant development is possible. It is intended that this book will be useful to the students, teachers and researchers, both in universities and research institutes, especially in relation to biological and agricultural sciences.
