Since the beginning of agricultural production, there has been a continuous effort to grow more and better quality food to feed ever increasing popula tions. Both improved cultural practices and improved crop plants have al lowed us to divert more human resources to non-agricultural activities while still increasing agricultural production. Malthusian population predictions continue to alarm agricultural researchers, especially plant breeders, to seek new technologies that will continue to allow us to produce more and better food by fewer people on less land. Both improvement of existing cultivars and development of new high-yielding cultivars are common goals for breeders of all crops. In vitro haploid production is among the new technologies that show great promise toward the goal of increasing crop yields by making similar germplasm available for many crops that was used to implement one of the greatest plant breeding success stories of this century, i. e., the development of hybrid maize by crosses of inbred lines. One of the main applications of anther culture has been to produce diploid homozygous pure lines in a single generation, thus saving many generations of backcrossing to reach homozygosity by traditional means or in crops where self-pollination is not possible. Because doubled haploids are equivalent to inbred lines, their value has been appreciated by plant breeders for decades. The search for natural haploids and methods to induce them has been ongoing since the beginning of the 20th century."

Biological nitrogen fixation (BNF) has become important in rice farming systems because this process diminishes the need for expensive chemical fertilizers which have been associated with numerous health and environmental problems. The extensive exploitation of BNF would provide economic benefits to small farmers, avoiding all malign influences of chemical fertilizers. Meanwhile, advances in biotechnology have brought rice genetics to the threshold of new opportunities for increasing rice production. This volume focuses, in six different sessions, on the role of BNF in the improvement of rice production in the light of the current state of the art of BNF technology transfer and diffusion. New ideas on BNF technology in research, extension information and inoculant technology are also included, together with the socio-economic impacts of using BNF in rice farm systems.

In the last two decades technological advances in isotope ratio mass spectrometry have been very rapid, opening up new possibilities for analysis of biological and environmental materials. The new instrumentation has facilitated faster analysis of samples via automated sample preparation and multi-isotope analysis of single samples, resulting in considerable cost savings, and enabling access to isotope analysis for many more researchers. These changes are reflected in the rapidly growing international literature on stable isotopes. While there have been some excellent books and review papers aimed at interpreting isotope signals in biology and environmental science, there have been fewer attempts to provide practical tools for researchers making forays into this exciting new arena. This book aims to address this inadequacy by providing a set of practical guidelines for the application of a range of novel and well proven stable isotope techniques to the fields of plant physiological ecology, agriculture, marine ecology and palaeoecology. The book is the outcome of a weeklong workshop held under the auspices of the Cooperative Research Centre for Legumes in Mediterranean Agriculture (CLIMA 1992 - 2000) at The University of Western Australia and the CSIRO Floreat Laboratories, Perth, Western Australia, in February 1999. The workshop was designed to provide practical tools and experiences for researchers and students concerned with how one goes about using stable isotopes in field investigations.

Adaptation and evolution of terrestrial plants depend, to a large extent, on their ability to acquire nutrients. This is a modern and integrative treatment of the mechanisms controlling plant nutrient uptake and how plants respond to changes in the environment. The following key topics are covered: soil nutrient bioavailability; root responses to variations in nutrient supply; nitrogen fixation; regulation of nutrient uptake by internal plant demand; root characteristics; kinetics of nutrient uptake; root architecture; life span; mycorrhizae; responses to climate change. This integrated view helps us to understand the mechanisms that govern present-day plant communities and is indispensable in models designed to predict the response of plants to a changing climate.

Like genomics, which defines genes in a genome irrespective of functionality, metabolomics profiles all metabolites in a biological sample irrespective of the chemical and physical properties of these molecules. Metabolomics can potentially define cellular processes by providing a measure of the ultimate phenotype of an organism, characterized by the collage of small molecules whose levels of accumulation is altered in response to genetic and environmentally induced changes in gene expression.

The assimilation of sulfur in higher plants and its reduction in metabolically important sulfur compounds are crucial factors determining plant growth and vigor and resistance to stresses. The present book discusses the aspects of sustainable crop production with sulfur, the importance of sulfur metabolites and sulfur metabolizing enzymes in abiotic stress management in plants. The book provides the most up-to-date reference on sulfur assimilation in plants.

Flowering plants dominate much of the Earth's surface and yet, as sessile organisms, they must constantly resist attack by numerous voracious herbivores. Survival in the face of an abundance of insect predators relies on sophisticated resistance systems allowing plants to escape from herbivory in time or in space, to confront herbivores directly, or to fight them indirectly by remarkable collaborations with other species. Until recently, plant resistance was believed to be constitutive, i.e. ever-present and independent from herbivore attack. However, plants were discovered to respond actively to herbivory through the mobilization of specific defenses, and this discovery opened an exciting new field of research.
This book provides a thorough overview of the anatomical, chemical, and developmental features contributing to plant defense, with particular emphasis on plant responses that are induced by wounding or herbivore attack.

Trees are a major component of the biosphere and have played an important part in the world's history and culture. With the modern challenges of global warming and dwindling fossil fuel reserves, trees, and in particular their wood, can provide solutions. Unfortunately, too little is known about the biology of these plants, due largely to a lack of appropriate techniques. In recognition of this, Wood Formation in Trees presents a variety of detailed techniques and protocols for the study of the cell and molecular biology of wood formation in trees. Internationally recognized experts, most of whom are the researchers who developed the techniques, speak with authority in this volume, and also provide first-hand tips and trade secrets to help the uninitiated master the techniques. The techniques reflect a hierarchical approach to the study of the developmental biology of wood formation: anatomical, biochemical and molecular-genetic. Trees are a tremendous but vastly under-appreciated natural resource. In an age where the natural product is so often modified to suit modern tastes and industrial processes, it is essential to understand how the natural product is made. The techniques in this book provide that essential information about the process of wood formation in trees.

Henslow's importance as Darwin's mentor is well established. He recommended Darwin for the post of naturalist on the Beagle and also encouraged him to read Lyell's pivotal geology text (also reissued in this series). While professor of botany at Cambridge, Henslow nurtured independent inquiry and acute observation in his students. These attributes are evident in this liberally illustrated 1835 book, which also reveals the influence of Candolle's Th orie El mentaire de la Botanique (1813) and Physiologie V g tale (1832). Henslow's book, like his meticulous research papers and his innovative lectures, included focussed investigations on the nature and stability of 'species'. Charles Darwin paid such close attention that he became known as 'the man who walks with Henslow', and Henslow's teachings were to echo through Darwin's writings, from his jottings in notebooks on the Beagle onward. This reissue gives modern readers easy access to the work of this inspirational scientist.

Woody plants have distinct growth and development habits. Being sessile and perennial species, woody plants are challenged by multiple stresses year-round or facing repeated stress attacks during their lives. A stress challenge in one season may impact the plant performance in other seasons or years; therefore, woody plants must develop specific mechanisms to minimize the damage caused by various stresses. Although all plant species share the basic physiological process, the unique characteristics of woody species in anatomy structure, body size, growth habit, and life expectancy contribute to significant differences in their responses to different environmental stresses compared to herbaceous plants. Written by a group of experts, Stress Physiology of Woody Plants, is comprised of 11 chapters profoundly describing the uniqueness of plant structure, growth and development, photosynthesis and respiration, and growth regulation in woody species. It summarizes findings in the responses of woody plants to major environmental stresses including drought, nutrient deficiency, salinity, low temperature, oxidative stress, heavy metal, and multiple stresses. Features: Provides a comprehensive review of physiological and molecular aspects of woody plants responding to some major environmental stresses. Bridges the gap between woody and herbaceous species in the field of general physiology and stress physiology. Describes the uniqueness of woody plants in plant structure, growth and development, photosynthesis and respiration, and growth regulation. Summarizes physiological and molecular responses to the environmental stresses in woody plants. This book serves as a textbook and major reference by students and researchers of plant physiology, horticulture, forestry, and plant molecular biology and teaches a better understanding of the mechanisms of plant response to individual or combined stresses in woody species.

This title includes a number of Open Access chapters. In horticulture, agriculture, and food science, plants' reproductive physiology is an important topic relating to fruits and vegetables, the main consumable parts of plants. All aspects of plant physiology, including plants' reproductive systems, are important to the production of food, fibers, medicine, cosmetics, and even fuels. This volume presents many new studies on plants' reproductive systems, including new research on sperm cells in plant reproduction; the effect of herbivory on plant reproduction; disturbances to functional diversity; plant genes, hormones, DNA; and much more.

Most plants rely on the co-existence with microorganisms: both groups benefit from these symbioses. It has been shown that a large number of specific genes in plants and microorganisms are only activated during these interactions. Of course, various microbes also act as pathogens.

Interactions between plants and microorganisms are often located on plant surfaces, such as leaf cuticles, seeds and mainly on the roots. The communication between plants and microbes is the main topic treated in "Plant Surface Microbiology," such as the signaling within a symbiosis, the molecular differences between symbiotic and pathogenic microorganisms, the role of microorganisms in the development of plants or in plant protection against deleterious agents. Further contributions are devoted to: the analysis of bacterial communities in the rhizosphere; microbial population genetics; aspects of mycorrhizal symbiosis; functional genomic approaches and the use of microorganisms as bio-indicator of soil disturbance.

Below the soil surface, the rhizosphere is the dynamic interface among plant roots, soil microbes and fauna, and the soil itself, where biological as well as physico-chemical properties differ radically from those of bulk soil. The Rhizosphere is the first ecologically-focused book that explicitly establishes the links from extraordinarily small-scale processes in the rhizosphere to larger-scale belowground patterns and processes. This book includes chapters that emphasize the effects of rhizosphere biology on long-term soil development, agro-ecosystem management and responses of ecosystems to global change. Overall, the volume seeks to spur development of cross-scale links for understanding belowground function in varied natural and managed ecosystems.
* First cross-scale ecologically-focused integration of information at the frontier of root, microbial, and soil faunal biology
* Establishes the links from extraordinarily small-scale processes in the rhizosphere to larger-scale belowground patterns and processes
* Includes valuable information on ecosystem response to increased atmospheric carbon dioxide and enhanced global nitrogen deposition
* Chapters written by a variety of experts, including soil scientists, microbial and soil faunal ecologists, and plant biologists

Harold Bloom's Shakespeare examines the sources and impact of Bloom's Shakespearean criticism. Through focused and sustained study of this writer and his best-selling book, this collection of essays addresses a wide range of issues pertinent to both general readers and university classes: the cultural role of Shakespeare and of a new secular humanism addressed to general readers and audiences; the author as literary origin; the persistence of character as a category of literary appreciation; and the influence of Shakespeare within the Anglo-American educational system. Together, the essays reflect on the ethics of literary theory and criticism.

Fruit ripening is an important aspect of fruit production. The timing of it affects supply chains and buying behaviour, and for consumers ripeness not only affects perceptions of health but has nutritional effects too. Ripeness is closely related to spoilage which has a major financial impact on agricultural industries. Currently there are fast moving developments in knowledge of the factors affecting fruit ripeness, and this up-to-date monograph seeks to draw together the disparate research in this area. The aim of the book is to produce a comprehensive account covering almost every area related to fruit ripening including the latest molecular mechanisms regulating fruit ripening, its impact on human nutrition and emerging research and technologies.

In this comprehensive and stimulating text and reference, the authors have succeeded in combining experimental data with current hypotheses and theories to explain the complex physiological functions of plants.

The authors vividly explain current research by references to experiments, they cite original literature in figures and tables, and, at the end of each chapter, list recent references that are relevant for a deeper analysis of the topic. In addition, an abundance of detailed and informative illustrations complement the text.

Photosynthesis: Photobiochemistry and Photobiophysics is the first single-authored book in the Advances in Photosynthesis Series. It provides an overview of the light reactions and electron transfers in both oxygenic and anoxygenic photosynthesis. The scope of the book is characterized by the time frame in which the light reactions and the subsequent electron transfers take place, namely between <=10-12 and >=10-3 second. The book is divided into five parts: An Overview; Bacterial Photosynthesis; Photosystem II & Oxygen Evolution; Photosystem I; and Proton Transport and Photophosphorylation. In discussing the structure and function of various protein complexes, we begin with an introductory chapter, followed by chapters on light-harvesting complexes, the primary electron donors and the primary electron acceptors, and finally the secondary electron donors. The discussion on electron acceptors is presented in the order of their discovery to convey a sense of history, in parallel with the advancement in instrumentation of increasing time resolution. The book includes a large number of stereo pictures showing the three-dimensional structure of various photosynthetic proteins, which can be easily viewed with unaided eyes. This book is designed to be used as a textbook in a graduate or upper-division undergraduate course in photosynthesis, photobiology, plant physiology, biochemistry, and biophysics; it is equally suitable as a resource book for students, teachers, and researchers in the areas of molecular and cellular biology, integrative biology, microbiology, and plant biology.

Environmental stresses represent the most limiting factors for agricultural productivity worldwide. These stresses impact not only current crop species, they are also significant barriers to the introduction of crop plants into areas that are not currently being used for agriculture. Stresses associated with temperature, salinity and drought, singly or in combination, are likely to enhance the severity of problems to which plants will be exposed in the coming decades. The present book brings together contributions from many laboratories around the world to discuss and compare our current knowledge of the role stress genes play in plant stress tolerance. In addition, strategies are discussed to introduce these genes and the processes that they encode into economically important crops, and the effect this will have on plant productivity.

This is the 5th edition of a well-established book Principles of Plant Nutrition which was first published in 1978. The same format is maintained as in previous editions with the primary aim of the authors to consider major processes in soils and plants that are of relevance to plant nutrition.This new edition gives an up-to-date account of the scientific advances of the subject by making reference to about 2000 publications. An outstanding feature of the book, which distinguishes it from others, is its wide approach encompassing not only basic nutrition and physiology, but also practical aspects of plant nutrition involving fertilizer usage and crop production of direct importance to human nutrition. Recognizing the international readership of the book, the authors, as in previous editions, have attempted to write in a clear concise style of English for the benefit of the many readers for whom English is not their mother tongue. The book will be of use to undergraduates and postgraduates in Agriculture, Horticulture, Forestry and Ecology as well as those researching in Plant Nutrition.

A number of abiotic factors such as drought, salinity, extreme temperatures, low or high light intensity, and deficiency or toxic levels of nutrients have huge impacts on crop productivity, and a furthering of our understanding of the molecular, biochemical, and physiological basis of stress tolerance has been widely recognized as critical. In Plant Stress Tolerance: Methods and Protocols, expert researchers cover the most important widely-used techniques, including cutting-edge strategies, in a manner that ensures effective results. Beginning with reviews on dehydration, salinity, and cold tolerance as well as on oxidative stress, the volume then continues with methods involving topics such as describing the identification of stress-regulated genes, proteins, and microRNAs using diverse approaches, measurement of osmotic adjustment, proline levels, enzymes involved in proline metabolism, and sugars as well as determination of ROS levels, lipid peroxidation, ion leakage, and the enzymes involved in ROS detoxification. Written in the highly successful Methods in Molecular Biology series format, chapters include introductions to their respective subjects, lists of the necessary materials and reagents, step-by-step, readily reproducible laboratory protocols, and tips on troubleshooting and avoiding known pitfalls.
