Although the term redox covers an important number of chemical reactions, biochemists are more familiar with reactions involving the reactions mediated by electron transfer chains associated with respiration, the thiol-disulfide exchanges and the reactions occurring in the presence of free radicals. More recently, the importance of these reactions in the living world and in medicine has been recognized by biochemists, biologists, physiologists, physicians, etc. The importance of the subject in both fundamental and is reflected by the abundance of interesting reviews applied science concerning the subject (Cadenas, 1989, Del Maestro, 1991) and books (Dreosti, 1991; Rice-Evans and Burdon, 1994; Armstrong, 1994) The aim of this chapter is to describe basic reactions known with references to reviews covering special subjects related to redox reactions. Transformation of energy in living organisms is mediated by complex biological systems such as electron transfer chains where the succession of redox reactions provides energy to the organisms. Molecular oxygen or dioxygen is an essential molecule and is the terminal acceptor of electrons during respiration in eukaryotes. In these organisms, the electron transfer chain is located in the mitochondrial membranes and produces adenosine triphosphate (ATP). In anaerobes, the electron acceptor is C0 , S, sulphate or nitrate ions 2 instead of 02.

The prospect of future climate change has stimulated research into the physiological responses of plants to stress. Water is a key factor controlling the distribution and abundance of plants in nature and the efficient uptake and subsequent transport of water within the plant is critical in hot, dry regions. This book, based on a meeting which focused on the failure of the hydraulic pathway within the xylem, brings together contributions from a range of experts who have worked on the cavitation of water in the transport system. The phenomenon of cavitation, discovered only in the 1960s, is now becoming recognised as being widespread and, whilst its ecological significance is a matter for further research, many scientists consider than embolism in the xylem predisposes plants to further water stress. Cavitation and refilling may, therefore, hold the key to vegetational response to climatic warming and drying. This book will provide a valuable compendium of information for those working in the plant and environmental sciences as well as for those whose interests lie in the more applied disciplines of agriculture and forestry.

Rice is one of the most important foods in the world. As the demand for rice continues to increase, there is an urgent need to increase yields in the face of such challenges as climate change, threats from pests and diseases and the need to make cultivation more resource-efficient and sustainable. Drawing on an international range of expertise, this collection focuses on ways of improving the cultivation of rice at each step in the value chain, from breeding to post-harvest storage. Volume 1 reviews research in physiology and breeding and its application to produce varieties with improved traits such as higher yields. It then goes on to discuss nutritional and other aspects of rice quality and the ways these can be enhanced. Achieving sustainable cultivation of rice Volume 1: Breeding for higher quality and yield will be a standard reference for rice scientists in universities, government and other research centres and companies involved in rice cultivation. It is accompanied by Volume 2 which reviews improvements in cultivation techniques, pest and disease management.

The eighteenth-century naturalist Erasmus Darwin (grandfather of Charles) argued that plants are animate, living beings and attributed them sensation, movement, and a certain degree of mental activity, emphasizing the continuity between humankind and plant existence. Two centuries later, the understanding of plants as active and communicative organisms has reemerged in such diverse fields as plant neurobiology, philosophical posthumanism, and ecocriticism. The Language of Plants brings together groundbreaking essays from across the disciplines to foster a dialogue between the biological sciences and the humanities and to reconsider our relation to the vegetal world in new ethical and political terms. Viewing plants as sophisticated information-processing organisms with complex communication strategies (they can sense and respond to environmental cues and play an active role in their own survival and reproduction through chemical languages) radically transforms our notion of plants as unresponsive beings, ready to be instrumentally appropriated. By providing multifaceted understandings of plants, informed by the latest developments in evolutionary ecology, the philosophy of biology, and ecocritical theory, The Language of Plants promotes the freedom of imagination necessary for a new ecological awareness and more sustainable interactions with diverse life forms.

Maize is one of the most important and widely grown cereal crops in the world and is a staple food for almost a billion people, particularly in the developing world. It has been estimated that maize yields need to increase by 60% by 2050. There is an urgent need to increase yields in the face of such challenges as climate change, threats from pests and diseases and the need to make cultivation more resource-efficient and sustainable. Drawing on an international range of expertise, this collection focuses on ways of improving the cultivation of maize at each step in the value chain, from breeding to post-harvest storage. Volume 1 reviews research on breeding and its use in improving nutritional quality and agronomic performance. It then goes on to discuss the challenges in translating these advances into effective outcomes for smallholders in the developing world. Achieving sustainable cultivation of maize Volume 1: From improved varieties to local applications will be a standard reference for cereal scientists in universities, government and other research centres and companies involved in maize cultivation. It is accompanied by Volume 2 which reviews improvements in cultivation techniques as well as the management of pests and diseases.

The authors consider small and poorly-studied groups of plant calcium-dependent protein kinases that directly interact with calmodulin molecules. In plants, Ca2+ activates calmodulin-like domain kinases that do not require calmodulin or phospholipids. Thus these kinases differ from both CaMK and PKC families prevalent in mammalian cells.Next, various strategies of purification of recombinant proteins using CaM-based purification systems are reviewed and discussed. Protein purification is a crucial process in biotechnology industries and life science research laboratories. Amongst these purification strategies, affinity purification has garnered a lot of attention due to its higher speed and selectivity, leading to enhanced purity in fewer steps.In the closing chapter, the authors describe atomic-level structures of Ca2+-bound CaM (Ca2+/CaM) bound to the PSD-95 N-terminal domain. The N-lobe of CaM forms a cap that binds to the N-terminus of PSD-95 and sterically blocks the palmitoylation of PSD-95 at Cys3 and Cys5. The CaM C-lobe forms hydrophobic contacts with PSD-95 residue Y12, and the Y12E mutation abolishes Ca2+-induced postsynaptic release of PSD-95.

Abiotic and biotic stresses adversely affect plant growth and productivity. The phytohormones regulate key physiological events under normal and stressful conditions for plant development. Accumulative research efforts have discovered important roles of phytohormones and their interactions in regulation of plant adaptation to numerous stressors. Intensive molecular studies have elucidated various plant hormonal pathways; each of which consist of many signaling components that link a specific hormone perception to the regulation of downstream genes. Signal transduction pathways of auxin, abscisic acid, cytokinins, gibberellins and ethylene have been thoroughly investigated. More recently, emerging signaling pathways of brassinosteroids, jasmonates, salicylic acid and strigolactones offer an exciting gateway for understanding their multiple roles in plant physiological processes. At the molecular level, phytohormonal crosstalks can be antagonistic or synergistic or additive in actions. Additionally, the signal transduction component(s) of one hormonal pathway may interplay with the signaling component(s) of other hormonal pathway(s). Together these and other research findings have revolutionized the concept of phytohormonal studies in plants. Importantly, genetic engineering now enables plant biologists to manipulate the signaling pathways of plant hormones for development of crop varieties with improved yield and stress tolerance. This book, written by internationally recognized scholars from various countries, represents the state-of-the-art understanding of plant hormones' biology, signal transduction and implications. Aimed at a wide range of readers, including researchers, students, teachers and many others who have interests in this flourishing research field, every section is concluded with biotechnological strategies to modulate hormone contents or signal transduction pathways and crosstalk that enable us to develop crops in a sustainable manner. Given the important physiological implications of plant hormones in stressful environments, our book is finalized with chapters on phytohormonal crosstalks under abiotic and biotic stresses.

The global population is growing at an alarming rate and is anticipated to reach about 9.6 billion by the end of 2050. Addressing the problem of food scarcity for budding population vis-a-vis environmental changes is the main challenge plant biologists face in the contemporary era. Plant growth and productivity are scarce in many areas of the world due to a wide range of environmental stresses. The productive land is dwindling progressively by various natural and anthropogenic means that lead to enormous crop losses worldwide. Plants often experience these stresses and have the ability to withstand them. However, when the stress exceeds the normal tolerance level, plants accumulate organic osmolytes, osmoprotectants, cryoprotectants and antioxidant enzymes, which helps them tolerate these stresses and assist in their acclimatization towards the particular ambiance needed for maintaining their growth and development. Physiological Mechanisms and Adaptation Strategies in Plants Under Changing Environment, Volume 1 discuss drought and temperature stresses and their mitigation through different means. This volume illuminates how plants that are bombarded by diverse and changing environmental stimuli, undergo appropriate physiological alterations that enable their survival. The information covered in the book is also useful in building apposite strategies to counter abiotic and biotic stresses in plants. Written by a diverse group of internationally renowned scholars, Physiological Mechanisms and Adaptation Strategies in Plants Under Changing Environment, Volume 1 is a concise yet comprehensive resource that will be beneficial for the researchers, students, environmentalists and soil scientists of this field.

Written by experts in their respective fields, Use of Microbes for the Alleviation of Soil Stresses, Volume 2: Alleviation of Soil Stress by PGPR and Mycorrhizal Fungi is a comprehensive and valuable resource for researchers and students interested in the field of microbiology and soil stresses.

Climate change is a complex phenomenon with a wide range of impacts on the environment. Biotic and abiotic stress are a result of climate change. Abiotic stress is caused by primary and secondary stresses which are an impediment to plant productivity. Prolonged exposure to these stresses results in altered metabolism and damage to biomolecules. Plants evolve defense mechanisms to withstand these stresses, e.g. synthesis of osmolytes, osmoprotectants, and antioxidants. Stress responsive genes and gene products including expressed proteins are implicated in conferring tolerance to the plant. This volume will provide the reader with a wide spectrum of information, including vital references. It also provides information as to how phytoconstituents, hormones and plant associated microbes help the plants to tolerate the stress. This volume also highlights the use of plant resources for ameliorating soil contaminants such as heavy metals. Dr. Parvaiz is Assistant professor in Botany at A.S.

Abiotic stress has a detrimental impact on the living organisms in a specific environment and constitutes a major constraint to global agricultural production. The adverse environmental conditions that plants encounter during their life cycle not only disturb their metabolic reactions, but also hamper their growth and development on cellular and whole plant levels. These conditions are of great concern, particularly for those countries whose economies primarily rely on agriculture. Under abiotic stresses, plants amalgamate multiple external stress cues to bring about a coordinated response and establish mechanisms to mitigate such stresses by triggering a cascade of events leading to enhanced tolerance. Physiological Mechanisms and Adaptation Strategies in Plants under Changing Environment, Volume 2 displays the ways by which plants utilize and integrate many common signals and subsequent pathways to cope with less favourable environmental conditions. The book also describes the use of contemporary tools for the improvement of plants under such stressed environments. Concise yet comprehensive, Physiological Mechanisms and Adaptation Strategies in Plants under Changing Environment, Volume 2 is an indispensable resource for researchers, students, environmentalists and many others in this burgeoning area of research.

Carnivorous plants have fascinated botanists, evolutionary biologists, ecologists, physiologists, developmental biologists, anatomists, horticulturalists, and the general public for centuries. Charles Darwin was the first scientist to demonstrate experimentally that some plants could actually attract, kill, digest, and absorb nutrients from insect prey; his book Insectivorous Plants (1875) remains a widely-cited classic. Since then, many movies and plays, short stories, novels, coffee-table picture books, and popular books on the cultivation of carnivorous plants have been produced. However, all of these widely read products depend on accurate scientific information, and most of them have repeated and recycled data from just three comprehensive, but now long out of date, scientific monographs. The field has evolved and changed dramatically in the nearly 30 years since the last of these books was published, and thousands of scientific papers on carnivorous plants have appeared in the academic journal literature. In response, Ellison and Adamec have assembled the world's leading experts to provide a truly modern synthesis. They examine every aspect of physiology, biochemistry, genomics, ecology, and evolution of these remarkable plants, culminating in a description of the serious threats they now face from over-collection, poaching, habitat loss, and climatic change which directly threaten their habitats and continued persistence in them.

Concentrates on symplasmic transport of small molecules, although the cell-to-cell transport of macromolecules will also be discussed. This book characterize the efficiency of symplasmic transport, mechanisms of molecule passage via plasmodesmata, and the external and internal factors that regulate plasmodesmatal conductivity. In this context, the book focused on the role of symplasmic domains in plant development, as well as the influence of environmental stresses on the plasmodesmata. Besides cell-to-cell symplasmic transport, the significance of long-distance symplasmic transport of solutes in phloem elements is also reviewed. Symplasmic Transport in Vascular Plants presents the mechanism of phloem transport, the processes of symplasmic loading and unloading, as well as the role of pre- and post-phloem transport, with special attention paid to symplasmic transport in wood. Finally, the relevance of the spread of both macromolecules and viruses, via plasmodesmata, is presented.
