Book Description
The scientific and economic significance of plant senescence means that much effort has been made to understand the processes involved and to devise means of manipulating them agriculturally. During the past few years there has been considerable progress in this regard, especially in the molecular, genetic and genomic aspects. Senescence has a tremendous impact on agriculture. For example, leaf senescence limits crop yield and biomass production, and contributes substantially to postharvest loss in vegetable and ornamental crops during transportation, storage and on shelves. In addition, proteins, antioxidants and other nutritional compounds are degraded during senescence. Senescing tissues also become more susceptible to pathogen infection, and some of the pathogens may produce toxins, rendering food unsafe. Mitotic senescence may also determine sizes of leaves, fruits and whole plants. This volume summarizes recent progresses in the physiology, biochemistry, cell biology, molecular biology, genomics, proteomics, and biotechnology of plant senescence. Beginning with a chapter on senescence-related terminology and our current knowledge of mitotic senescence in plants (a less well-studied area), the book focuses on post-mitotic senescence, and includes chapters addressing the senescence of leaves, flowers and fruits. Later chapters examine the development of various new biotechnologies for manipulating the senescence processes of fruit and leaves, some of which are approaching commercialization. The book is directed at researchers and professionals in plant molecular genetics, physiology and biochemistry.

Book Description
Senescence Signalling and Control in Plants discusses the studies showing the importance of hormone action on developmental senescence. It shows the involvement of various signaling components (such as EIN2, LOX2) and transcription factors (such as oresara1 or ORE1) in controlling hormonal activity during senescence. Further, the involvement of various micro RNAs (miR164, miR319) in regulating leaf senescence are discussed. Through this book, the authors throw light on all the reverse and forward genetic approaches to reveal the role of various other phytohormones regulating plant senescence and the molecular mechanisms involved. Chapters on relevant topics are contributed by experts working in the area, making this a comprehensive treatise designed to provide an in-depth analysis on the subject matter. - Throws light on the involvement of hormones (other than the well- known hormones cytokine and ethylene) in plant senescence - Shows the underlying mechanisms on the hormonal actions during senescence - Exhibits the involvement of microRNAs during this important plant developmental process

Book Description
Senescence and Aging in Plants reviews the state of knowledge in the processes involved in plant senescence and aging. The book begins by discussing the emergence of senescence as a concept; experimental analysis of senescence; and patterns of senescence. It then examines membrane deterioration during senescence; photosynthesis in relation to leaf senescence; senescence of detached plant organs; changing patterns of nucleic acid and protein synthesis during senescence; and degradative and associated assimilatory aspects of nitrogen removal. This is followed by chapters on aspects of ethylene that may impinge upon its role in promoting senescence of higher plants; the role of cytokinins in plant senescence; the promoters and retardants of senescence; and the role of calcium in plant senescence. The concept of whole plant senescence is discussed, which can be subdivided into patterns, correlative controls, cessation of vegetative growth, declining assimilatory processes, assimilate partitioning, and hormonal controls. The final chapters cover the deterioration of cellular membranes during the plant aging process and seed aging.

Book Description
The formation, dispersal and germination of seeds are crucial stages in the life cycles of gymnosperm and angiosperm plants. The unique properties of seeds, particularly their tolerance to desiccation, their mobility, and their ability to schedule their germination to coincide with times when environmental conditions are favorable to their survival as seedlings, have no doubt contributed significantly to the success of seed-bearing plants. Humans are also dependent upon seeds, which constitute the majority of the world’s staple foods (e.g., cereals and legumes). Seeds are an excellent system for studying fundamental developmental processes in plant biology, as they develop from a single fertilized zygote into an embryo and endosperm, in association with the surrounding maternal tissues. As genetic and molecular approaches have become increasingly powerful tools for biological research, seeds have become an attractive system in which to study a wide array of metabolic processes and regulatory systems. Seed Development, Dormancy and Germination provides a comprehensive overview of seed biology from the point of view of the developmental and regulatory processes that are involved in the transition from a developing seed through dormancy and into germination and seedling growth. It examines the complexity of the environmental, physiological, molecular and genetic interactions that occur through the life cycle of seeds, along with the concepts and approaches used to analyze seed dormancy and germination behavior. It also identifies the current challenges and remaining questions for future research. The book is directed at plant developmental biologists, geneticists, plant breeders, seed biologists and graduate students.

Book Description
The plant hormone ethylene is one of the most important, being one of the first chemicals to be determined as a naturally-occurring growth regulator and influencer of plant development. It was also the first hormone for which significant evidence was found for the presence of receptors. This important new volume in Annual Plant Reviews is broadly divided into three parts. The first part covers the biosynthesis of ethylene and includes chapters on S-adenosylmethionine and the formation and fate of ACC in plant cells. The second part of the volume covers ethylene signaling, including the perception of ethylene by plant cells, CTR proteins, MAP kinases and EIN2 / EIN3. The final part covers the control by ethylene of cell function and development, including seed development, germination, plant growth, cell separation, fruit ripening, senescent processes, and plant-pathogen interactions. The Plant Hormone Ethylene is an extremely valuable addition to Wiley-Blackwell's Annual Plant Reviews. With contributions from many of the world's leading researchers in ethylene, and edited by Professor Michael McManus of Massey University, this volume will be of great use and interest to a wide range of plant scientists, biochemists and chemists. All universities and research establishments where plant sciences, biochemistry, chemistry, life sciences and agriculture are studied and taught should have access to this important volume.

Book Description
Plant Hormones: Biosynthesis and Mechanisms of Action is based on research funded by the Chinese government's National Natural Science Foundation of China (NSFC). This book brings a fresh understanding of hormone biology, particularly molecular mechanisms driving plant hormone actions. With growing understanding of hormone biology comes new outlooks on how mankind values and utilizes the built-in potential of plants for improvement of crops in an environmentally friendly and sustainable manner. This book is a comprehensive description of all major plant hormones: how they are synthesized and catabolized; how they are perceived by plant cells; how they trigger signal transduction; how they regulate gene expression; how they regulate plant growth, development and defense responses; and how we measure plant hormones. This is an exciting time for researchers interested in plant hormones. Plants rely on a diverse set of small molecule hormones to regulate every aspect of their biological processes including development, growth, and adaptation. Since the discovery of the first plant hormone auxin, hormones have always been the frontiers of plant biology. Although the physiological functions of most plant hormones have been studied for decades, the last 15 to 20 years have seen a dramatic progress in our understanding of the molecular mechanisms of hormone actions. The publication of the whole genome sequences of the model systems of Arabidopsis and rice, together with the advent of multidisciplinary approaches has opened the door to successful experimentation on plant hormone actions. - Offers a comprehensive description of all major plant hormones including the recently discovered strigolactones and several peptide hormones - Contains a chapter describing how plant hormones regulate stem cells - Offers a fresh understanding of hormone biology, particularly molecular mechanisms driving plant hormone actions - Discusses the built-in potential of plants for improvement of crops in an environmentally friendly and sustainable manner

Book Description
The development of phosphorus (P)-efficient crop varieties is urgently needed to reduce agriculture's current over-reliance on expensive, environmentally destructive, non-renewable and inefficient P-containing fertilizers. The sustainable management of P in agriculture necessitates an exploitation of P-adaptive traits that will enhance the P-acquisition and P-use efficiency of crop plants. Action in this area is crucial to ensure sufficient food production for the world’s ever-expanding population, and the overall economic success of agriculture in the 21st century. This informative and up-to-date volume presents pivotal research directions that will facilitate the development of effective strategies for bioengineering P-efficient crop species. The 14 chapters reflect the expertise of an international team of leading authorities in the field, who review information from current literature, develop novel hypotheses, and outline key areas for future research. By evaluating aspects of vascular plant and green algal P uptake and metabolism, this book provides insights as to how plants sense, acquire, recycle, scavenge and use P, particularly under the naturally occurring condition of soluble inorganic phosphate deficiency that characterises the vast majority of unfertilised soils, worldwide. The reader is provided with a full appreciation of the diverse information concerning plant P-starvation responses, as well as the crucial role that plant–microbe interactions play in plant P acquisition. Annual Plant Reviews, Volume 48: Phosphorus Metabolism in Plants is an important resource for plant geneticists, biochemists and physiologists, as well as horticultural and environmental research workers, advanced students of plant science and university lecturers in related disciplines. It is an essential addition to the shelves of university and research institute libraries and agricultural and ecological institutions teaching and researching plant science.
