Book Description
The first comprehensive review of the occurrence and explanation of seed dormancy in grasses is presented in this volume. An understanding of seed dormancy is of considerable significance to world agriculture and the global economy, since grasses are a principal source of food for humankind and play an essential role in stabilizing the land surface of much of the globe. Experimental evidence is considered in depth for a single species, the wild oat (Avena fatua), probably the most widely studied species for understanding seed dormancy in the plant kingdom. The evidence for this species is compared with other examples among the Gramineae to reach some general conclusions about the nature of seed dormancy in grasses.

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
Seeds: Ecology, Biogeography, and Evolution of Dormancy and Germination provides a working hypothesis of the ecological and environmental conditions under which carious kinds of seed dormancy have developed. It also presents the seed germination of morethan 3500 species of trees, shrubs, vines, and herbaceous species.

Book Description
During germination, the most resistant stage of the life cycle - the seed - changes to the most sensitive stage, namely the seedling. Therefore, in desert plant species seed dispersal and subsequent germination in the optimum time an place place are particularly critical parameters. Discussed here are the ways and means by which desert plants have adapted through the course of evolution to their extreme environment. Two such strategies which have evolved are a) plants with relatively large and protected seeds which germinate when the chance of seedling survival is high and the risk relatively low or b) those with an opportunistic strategy: minute seeds which germinate after low rainfall under high risk for seedling survival if additional rain does not follow. Most species adopt a combination of the two mechanisms. Species have adapted both genotypically and phenotypically, both aspects of which are also discussed in this thorough text. The reader is provided with a good understanding of the complex influences on each seed traced through from initial development to germination stage regarding germination preparation and subsequent survival.

Book Description
Dormancy is a mechanism found in several plant species developed through evolution, which allows plants to survive in adverse conditions and ensure their perpetuation. This mechanism, however, can represent a barrier that can compromise the development of the species of interest, and therefore, the success of its cultivation. It is important to understand the causes, effects, and mechanisms, as well as the technologies for overcoming dormancy of buds, seeds, and plant propagules. In this context, this publication has as a main objective of offering an in-depth view of the dormancy process in cultivated plants, based on a survey of more recent international research on the subject. Written by several researchers from different institutions of education and research, this book presents information on the most diverse species of plants of agronomic and forestry interest. In addition to the physiological, biochemical, and genetic aspects, the chapters also address the possible causes of dormancy, as well as technological issues that are essential for the successful cultivation of several economically important species. The focus of this publication is on temperate fruit species. Classical examples of temperate plants that present dormancy are fruit trees such as apple, pear, quince, apricot, and cherry. These pome and stone fruits are typical representatives of a deciduous temperate climate, wherein trees drop their leaves at the end of the reproductive cycle, consequently entering dormancy. Dormancy has its control effected by factors of a hormonal nature, where the hormone promoters and growth inhibitors are balanced. Edaphoclimatic conditions also affect plant dormancy periods, for the most part through temperature changes. Other chapters in this book are dedicated especially to potatoes, vegetables, as well as forest and forage species, which makes this text a complete and comprehensive work on the subject.

Book Description
Plants are forced to adapt for a variety of reasons— protection, reproductive viability, and environmental and climatic changes. Computational tools and molecular advances have provided researchers with significant new insights into the molecular basis of plant adaptation. Molecular Mechanisms in Plant Adaptation provides a comprehensive overview of a wide variety of these different mechanisms underlying adaptation to these challenges to plant survival. Molecular Mechanisms in Plant Adaptation opens with a chapter that explores the latest technological advances used in plant adaptation research, providing readers with an overview of high-throughput technologies and their applications. The chapters that follow cover the latest developments on using natural variation to dissect genetic, epigenetic and metabolic responses of plant adaptation. Subsequent chapters describe plant responses to biotic and abiotic stressors and adaptive reproductive strategies. Emerging topics such as secondary metabolism, small RNA mediated regulation as well as cell type specific responses to stresses are given special precedence. The book ends with chapters introducing computational approaches to study adaptation and focusing on how to apply laboratory findings to field studies and breeding programs. Molecular Mechanisms in Plant Adaptation interest plant molecular biologists and physiologists, plant stress biologists, plant geneticists and advanced plant biology students.
