Molecular Breeding and Nutritional Aspects of Buckwheat describes the general characterization and genetic diversity of buckwheat (family Polygonaceae, genus Fagopyrum) around the globe (especially in Russia, China, India, and Eastern Europe), the arid and cool regions where it is most frequently consumed, and nutritional information on a variety of buckwheat uses, including tea, groats, flour, and noodles. With detailed information on buckwheat regeneration, genetic transformation, gene function analysis, and the metabolic engineering of bioactive compounds, the book guides readers through a variety of buckwheat varietal adaptations, providing foundation information on which additional research should be conducted. It is divided into four parts, including genetic resource and phylogenetic relationship, food nutrition, growth and cultivation, and molecular breeding, with each section providing insights into the most current developments.

Cellulase is a key enzyme of industrial interest and plays a crucial role in the hydrolysis of cellulose, a prime component of plant cell walls. Cellulase covers a broad area in the global market of industrially important enzymes and it is considered as the third largest industrial enzyme globally. Additionally, cellulase contributes about 20% of the total enzyme market globally because of its massive demand in various industries such as in biofuel production, pulp, paper, textile, food, and beverages, as well as in detergent industries. Among these, the demand of cellulase may become frequently selected in the commercial production of biofuels in the future and thus will further increase demand of cellulase in the biofuel industry. Because biofuel production is still not realized in a cost-effective, practical implementation due to its high cost (the higher cost of biofuels is due to higher production costs of enzymes), there is a need to introduce these types of approaches, which will help to lower the cost of enzyme production for developing overall economic biofuel production.

Over recent years, progress in micropropagation has not been as rapid as many expected and, even now, relatively few crops are produced commercially. One reason for this is that the biology of material growing in vitro has been insufficiently understood for modifications to standard methods to be made based on sound physiological principles. However, since 1984, tissue culture companies and others have invested considerable effort to reduce the empirical nature of the production process. The idea of the conference "Physiology, Growth and Development of Plants and Cells in Culture"(Lancaster, 1992) was to introduce specialists in different areas of plant physiology to micropropagators, with the express aims of disseminating as wide a range of information to as large a number of participants as possible, and beginning new discussions on the constraints and potentials affecting the development of in vitro plant production methods. This book is based on presentations from the conference and has been divided into two main sections, dealing with aspects of the in vitro environment - light, nutrients, water, gas - and with applied aspects of the culture process - morphogenesis, acclimation, rejuvenation, contamination.

Bioremediation is a rapidly advancing field and the technology has been applied successfully to remediate many contaminated sites. The goal of every soil remediation method is to enhance the degradation, transformation, or detoxification of pollutants and to protect, maintain and sustain environmental quality.

Advances in our understanding of the ecology of microbial communities capable of breaking down various pollutants and the molecular and biochemical mechanisms by which biodegradation occurs have helped us in developing practical soil bioremediation strategies. Chapters dealing with the application of biological methods to soil remediation are contributed from experts authorities in the area of environmental science including microbiology and molecular biology from academic institutions and industry."

The global population is growing at an alarming rate and is anticipated to reach about9.6billion bythe endof 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.

This book describes the various applications of microorganisms in improving plant growth, health and the efficiency of phytochemical production. The chapters trace topics such as the role of PGPRs in improving salt stress and heavy metal tolerance in plants; the prevention and control of plant diseases; boosting soil fertility and agriculture productivity; the induction of secondary metabolite biosynthesis in medicinal and aromatic plants; the enhancement of phytochemical levels, and the action mechanisms, diversity and characterization of PGPRs. The reviews will be of interest for scientists in the fields of agriculture, microbiology, soil biology, plant breeding and herbal medicinal products.

The first edition of this higly regarded text was published in 1979 to provide a general introduction to the principles of plant breeding. It has been out of print since late 1993 and a new edition is long overdue as there are no up to date and comprehensive single volumes on the subject in print.

The original text has been amended and enhanced where there have been advances in plant breeding to provide coverage of recent developments relevant to crop improvement, such as intellectual property rights, biotechnology and the use and conservation of genetic resources. The emphasis of the text will be, as it was for the first edition, on the principles of plant breeding and the expanded range of techniques now available for effective crop improvement.

Reproduction is a fundamental feature of life, it is the way life persists across the ages. This book offers new, wider vistas on this fundamental biological phenomenon, exploring how it works through the whole tree of life. It explores facets such as asexual reproduction, parthenogenesis, sex determination and reproductive investment, with a taxonomic coverage extended over all the main groups - animals, plants including 'algae', fungi, protists and bacteria. It collates into one volume perspectives from varied disciplines - including zoology, botany, microbiology, genetics, cell biology, developmental biology, evolutionary biology, animal and plant physiology, and ethology - integrating information into a common language. Crucially, the book aims to identify the commonalties among reproductive phenomena, while demonstrating the diversity even amongst closely related taxa. Its integrated approach makes this a valuable reference book for students and researchers, as well as an effective entry point for deeper study on specific topics.

The grasses and legumes grown in pastures and rangelands form the basis of the worldwide animal production industry. Some species also have a significant role in the sport and leisure industry, for playing surfaces such as golf courses and football fields. It is therefore vitally important to ensure that seed supplies of appropriate species are available for use on a commercial scale. This book is published in association with the International Herbage Seed Production Research Group. It brings together leading researchers and along with its companion volume Forage Seed Production Volume 2: Tropical and Subtropical Species (to be published in late 1998), provides the definitive resource for all those concerned with breeding and profitable seed production for grasses and legumes used within grazing systems or recreation and amenity provision. The book is in two parts. Part 1 covers all aspects relevant to seed production, including improving seed yield and quality, crop management, harvesting, processing and the international seed trade. Part 2 consists of eleven case studies from eight countries covering three continents. This book and its companion should be read by all seed scientists involved in the breeding and commercial production of grass and legume seed. They also represent a valuable asset for all commercial seed suppliers. Additionally, the information presented within the book is important for all students and lecturers within departments of agriculture and plant breeding.

Plant Adaptation and Crop Improvement focuses on the opportunities for increasing the efficiency of crop improvement by understanding the basis of variation for plant adaptation in agricultural production systems. Crop improvement strategies based on combinations of the statistical modelling methodologies used by plant breeders and the crop modelling methodologies used by crop physiologists/agronomists are developed and discussed. The book captures much of the experience of scientists from around the world who have worked on the challenging problem of achieving crop improvement in variable crop production systems. It represents a major synthesis for workers in plant breeding, crop physiology and agronomy.

Environmental conditions and changes, irrespective of source, cause a variety of stresses, one of the most prevalent of which is salt stress. Excess amount of salt in the soil adversely affects plant growth and development, and impairs production. Nearly 20% of the world's cultivated area and nearly half of the world's irrigated lands are affected by salinity. Processes such as seed germination, seedling growth and vigour, vegetative growth, flowering and fruit set are adversely affected by high salt concentration, ultimately causing diminished economic yield and also quality of produce. Most plants cannot tolerate salt-stress. High salt concentrations decrease the osmotic potential of soil solution, creating a water stress in plants and severe ion toxicity. The interactions of salts with mineral nutrition may result in nutrient imbalances and deficiencies. The consequence of all these can ultimately lead to plant death as a result of growth arrest and molecular damage. To achieve salt-tolerance, the foremost task is either to prevent or alleviate the damage, or to re-establish homeostatic conditions in the new stressful environment. Barring a few exceptions, the conventional breeding techniques have been unsuccessful in transferring the salt-tolerance trait to the target species. A host of genes encoding different structural and regulatory proteins have been used over the past 5-6 years for the development of a range of abiotic stress-tolerant plants. It has been shown that using regulatory genes is a more effective approach for developing stress-tolerant plants. Thus, understanding the molecular basis will be helpful in developing selection strategies for improving salinity tolerance. This book will shed light on the effect of salt stress on plants development, proteomics, genomics, genetic engineering, and plant adaptations, among other topics. The book will cover around 25 chapters with contributors from all over the world.

One of the oldest scientific traditions, plant breeding began in Neolithic times with methods as simple as saving the seeds of desirable plants and sowing them later. It was not until the re-encounter with Mendel's discoveries thousands of years later, the genetic basis of breeding was understood. Developments following have provided further insight into how genes acting alone or in concert with other genes and the environment, result in a particular phenotype. From Abaxial to Zymogram, the third edition of Dictionary of Plant Breeding contains clear and useful definitions of the terms associated with plant breeding and related scientific/technological disciplines. It defines jargon; provides helpful tables, examples, and breeding schemes; and includes a list of crop plants with salient details. Packed with data and organized to make that data easy to access, this revised and expanded reference provides comprehensive coverage of the latest discoveries in cytogenetics, molecular genetics, marker-assisted selection, experimental gene transfer, CRISPR technology, seed sciences, crop physiology, and genetically modified crops. Features: Provides a comprehensive list of technical terms used in plant breeding Explores the historical development of crop improvement Discusses applications of molecular genetics and biotechnology Includes numerous figures, drawings, tables, and schemes supplementing the glossary A complex subject, plant breeding draws from many scientific and technological disciplines, often making it difficult to know the precise meanings of many terms and to accurately interpret specific concepts. As in the previous editions, this dictionary unifies concepts by including the specific terms of plant breeding and terms that are adjusted from other disciplines. Drawing on Rolf Schlegel's 50 years of experience, the book provides an encyclopedic list of commonly used technical terms that reflect the latest developments in the field.

This book is open access under a CC BY-NC 2.5 license.

Wherever appropriate, it is shown how ecology and genetics interact, presenting a rounded picture of the population biology of plants.

Topics covered include variation and its inheritance, genetic markers including molecular markers, plant breeding systems, ecological genetics, intraspecific interactions, population dynamics, regional dynamics and metapopulations, competition and coexistence, and the evolution of breeding systems and life history. An extensive bibliography provides access to the recent literature that will be invaluable to students and academics alike.
Effective integration of plant population ecology, population genetics and evolutionary biology.
The new edition is thoroughly revised and now includes molecular techniques.
The genetics chapters have been completely rewritten by a new co-author, Deborah Charlesworth.

Plant Breeding Reviews presents state-of-the-art reviews on plant genetics and the breeding of all types of crops by both traditional means and molecular methods. Many of the crops widely grown today stem from a very narrow genetic base; understanding and preserving crop genetic resources is vital to the security of food systems worldwide. The emphasis of the series is on methodology, a fundamental understanding of crop genetics, and applications to major crops. It is a serial title that appears in the form of one or two volumes per year.

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.

This Soil Biology volume examines our current understanding of the mechanisms involved in the beneficial effects transferred to plants by endophytes such as rhizobial, actinorhizal, arbuscular mycorrhizal symbionts and yeasts. Topics presented include how symbiosis starts on the molecular level; chemical signaling in mycorrhizal symbiosis; genomic and functional diversity of endophytes; nitrogen fixation; nutrient uptake and cycling; as well as plant protection against various stress conditions. Further, the use of beneficial microorganisms as biopesticides is discussed, particularly the application of Plant Growth Promoter Rhizobacteria (PGPR) in agriculture with the aim to increase yields.

In this 1948 book, of which the scope and treatment are quite unique, Dr Bell gives an account of all cultivated farm plants in Britain at the time. In the first chapters he deals with general matters. Then, in the main part of the book he describes individually the different crop plants and their place in British agriculture, directing special attention to grasses and grassland. Crops are grouped according to their botanical relationship, and the botanical characters that give economic importance are described. The foundations of the book are, therefore, botanical; but the practical agricultural outcome is never lost sight of, nor are the wider implications, the importance of crops to the development of civilised life and modern standards of living. Crop improvement is discussed throughout the book, and a special chapter is devoted to seed stocks and improved varieties and strains. The book is illustrated with 36 photographs.

Originally published in 1990, this text brings together a detailed review by acknowledged authorities of grass reproductive biology. Grasses are our most important plants whether for agriculture or conservation. Essential to contemporary awareness of grasses is an understanding of their role in sustaining ecologically fragile environments, and the relative importance of annual and perennial reproduction is examined here with particular reference to indigenous dryland grasses marginal to major deserts. Molecular biology and tissue culture allow us to intervene in reproductive systems and the issues include a fundamental revision of the concept of double fertilisation grass pollen in relation to human allergy and the prospects for developing wheat male sterility. The book concludes with an overview to assess how far evolution of the grass is coming under human control.

From their ability to use energy from sunlight to make their own food, to combating attacks from diseases and predators, plants have evolved an amazing range of life-sustaining strategies. Written with the non-specialist in mind, John King's lively natural history explains how plants function, from how they gain energy and nutrition to how they grow, develop and ultimately die. New to this edition is a section devoted to plants and the environment, exploring how problems created by human activities, such as global warming, pollution of land, water and air, and increasing ocean acidity, are impacting on the lives of plants. King's narrative provides a simple, highly readable introduction, with boxes in each chapter offering additional or more advanced material for readers seeking more detail. He concludes that despite the challenges posed by growing environmental perils, plants will continue to dominate our planet.

Reproductive biology is the basis of species improvement and a thorough understanding of this is needed for plant improvement, whether by conventional or biotechnological methods. This book presents an up to date and comprehensive description of reproduction in lower plants, gymnosperms and higher plants. It covers general plant biology, pollination, pollen-pistil interaction, post-fertilization changes, and seed dormancy.

Plant tissue culture is an essential component of Biotechnology which has gained unbeatable recognition in plant sciences for successful micropropagation and improvement of plant species, leading to the commercial application. A number of plant species have been investigated around the globe. This book presents current research on the application of in vitro technology in the improvement of Balanites aegyptiaca Del., a medicinal plant of semi-arid tropics. The worldwide importance of forestry, summed to the lengthy generation cycles of tree species, makes unavoidable development of new technologies that complement conventional tree breeding programmes in order to obtain improved genotypes. Recently, a new set of tools has become available in the past 20 years that combined with traditional plant breeding will allow scientists to generate products that are genetically improved varieties of the future. These set of tools come under the general title of Biotechnology . The three specific biotechnological tools have been successfully used in several programmes of plant conservation, namely, tissue culture techniques for in vitro propagation, the use of molecular markers to assess the degree of variability among population and techniques of long-term conservation such as encapsulation and cryopreservation. Plant tissue culture techniques are particularly relevant and become an alternative not only for large scale propagation of individuals that are threatened, reduce production costs and increase gains to the industry, but also to provide ecological advantages as in phytoremediation or in the establishment of artificial plantings in weed infested site. The book gives a complete documentation of the results and demonstration of Balanites aegyptiaca conducted by the authors over the past 5 years. The end-to-end approach developed through plant tissue culture techniques is reflected in the book and there has been a successful transfer of technology from lab to field. The authors hope that this information would provide valuable data and also be a reference material for future research activities in this area."

Molecular biology techniques have considerably increased our understanding of mechanisms underlying the control of flower initiation, development, function and senescence, processes which can be critically important in managing the yield of agricultural crops. The book covers the molecular and genetic control of flower morphogenesis in particular species and discusses the role and regulation of gene expression in the development, together with action of the male and female gametes in plant reproduction. The considerable variation in longevity of flowers and pattern of senescence are reviewed. The importance of ethylene in the control mechanism is discussed using examples of both ethylene-sensitive and insensitive species. The book will be vital to those researching floral physiology, and a useful reference for undergraduates studying relevant botanical courses.
