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.
The rapid population growth and the increase in the per capita income, especially in the group of emerging countries referred to as BRIC countries (Brazil, Russia, India, China and South Africa) has created huge pressure for the expansion of the agricultural growing area and the crop yields to meet the rising demand. As a result, many areas that have been considered marginal for growing crops, due to their low fertility, drought, salinity, and many other abiotic stresses, have now been incorporated in the production system. Additionally, climate change has brought new challenges to agriculture to produce food, feed, fiber and biofuels. To cope with these new challenges, many plant breeding programs have reoriented their breeding scope to stress tolerance in the last years. The authors of this book have collected the most recent advances and discoveries applied to breeding for abiotic stresses in this book, starting with new physiological concepts and breeding methods, and moving on to discuss modern molecular biological approaches geared to the development of improved cultivars tolerant to most sorts of abiotic stress. Written in an easy to understand style, this book is an excellent reference work for students, scientists and farmers interested in learning how to breed for abiotic stresses scenarios, presenting the state-of-the-art in plant stresses and allowing the reader to develop a greater understanding of the basic mechanisms of tolerance to abiotic stresses and how to breed for them.
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.
To cope with the increasing problems created by agrochemicals such as plant fertilizers, pesticides and other plant protection agents, biological alternatives have been developed over the past years. These include biopesticides, such as bacteria for the control of plant diseases, and biofertilizer to improve crop productivity and quality. Especially plant growth promoting rhizobacteria (PGPR) are as effective as pure chemicals in terms of plant growth enhancement and disease control, in addition to their ability to manage abiotic and other stresses in plants. The various facets of these groups of bacteria are treated in this Microbiology Monograph, with emphasis on their emergence in agriculture. Further topics are Bacillus species that excrete peptides and lipopeptides with antifungal, antibacterial and surfactant activity, plant-bacteria-environment interactions, mineral-nutrient exchange, nitrogen assimilation, biofilm formation and cold-tolerant microorganisms.
SpringerBriefs in Biotech Patents presents timely reports on intellectual properties (IP) issues and patent aspects in the field of biotechnology. In this volume the limits of patentability are addressed, a question that is often raised when it comes to biotechnological inventions: The first section addresses current issues in the patentability of plants produced by essentially biological processes including the controversy between farmer's privilege and patent exhaustion with respect to seeds in the US. The second section examines the patentability of human embryonic stem cells in Europe and the US, also considering alternative technologies with respect to their practicability and patentability. The third section focuses on the patentability of genes and nucleic acids, especially the issue of patenting of encoding genes and nucleic acids.
Molecular farming in plants is a relatively young subject of sciences. As plants can offer an inexpensive and convenient platform for the large-scale production of recombinant proteins with various functions, the driven force from the giant market for recombinant protein pharmaceuticals and industrial enzymes makes this subject grow and advance very quickly. To summarize recent advances, current challenges and future directions in molecular farming, international authorities were invited to write this book for researchers, teachers and students who are interested in this subject. This book, with the focus on the most advanced cutting-edge breakthroughs, covers all the essential aspects of the field of molecular farming in plants: from expression technologies to downstream processing, from products to safety issues, and from current advances and holdups to future developments.
This book is a collection of chapters concerning the use of biomass for the sustainable production of energy and chemicals-an important goal that will help decrease the production of greenhouse gases to help mitigate global warming, provide energy security in the face of dwindling petroleum reserves, improve balance of payment problems and spur local economic development. Clearly there are ways to save energy that need to be encouraged more. These include more use of energy sources such as, among others, manure in anaerobic digesters, waste wood in forests as fuel or feedstock for cellulosic ethanol, and conservation reserve program (CRP) land crops that are presently unused in the US. The use of biofuels is not new; Rudolf Diesel used peanut oil as fuel in the ?rst engines he developed (Chap. 8), and ethanol was used in the early 1900s in the US as automobile fuel [Songstad et al. (2009) Historical perspective of biofuels: learning from the past to rediscover the future. In Vitro Cell Dev Biol Plant 45:189-192). Brazil now produces enough sugar cane ethanol to make up about 50% of its transportation fuel needs (Chap. 4). The next big thing will be cellulosic ethanol. At present, there is also the use of Miscanthus x giganteous as fuel for power plants in the UK (Chap. 2), bagasse (sugar cane waste) to power sugar cane mills (Chap. 4), and waste wood and sawdust to power sawmills (Chap. 7).
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."
Plant breeding, the domestication and systematic improvement of crop species, is the basis of past and present agriculture. Our so called primitive progenitors selected practically all our present-day crop plants, and the improvement wrought through millenia of selection has so changed some of them that in many cases their links to the past have been obliterated. There is no doubt that this ranks among the greatest of human achievements. Although plant breeding has been a continuous empirical activity for as long as humans have forsaken the vagaries and thrill of hunting for the security and toil of agriculture, genetic crop improvement is now very much of a twentieth-century discipline. Its scientific underpinnings date to the beginning of this century with the discovery of Gregor Mendel's classic 1865 paper on the inheritance of seven characters in the garden pea. If any science can be traced to single event, the best example is surely found in the conception of modern genetics that appears in this single creative work. The relationship of plant breeding progress to advances in genetics has become closely entwined. Mendel himself was concerned with crop improvement and worked on schemes for apple and pear breeding. Plant breeding also has claims on other scientific and agricultural disci plines-botany, plant pathology, biochemistry, statistics, taxonomy, entomology, and cytology, to name a few-and has also impinged on our social, ethical, economic, and political consciousness."
The food, feed, ?ber, and fuel needs of the changing world pose the challenge of doubling or tripling of world food, feed, and ?ber production by the year 2050 to meet the needs of a 11 billion global population. In addition, the dramatic changes in food prices in the recent years further warrant that production and productivity need to be enhanced to ensure adequate supplies. Biotechnology can make a signi?cant contribution to this effort as demonstrated by cotton and other crops; the new advances in biotechnology have made it possible to develop plants that contain genes that were not possible to be developed by sexual means. Cotton has been a leader in the use of biotechnology. With the introduction of Bt cotton, followed by stacked cotton products (insect and herbicide tolerance) and extensive use of molecular breeding tools, cotton cultivation has been much improved. The contributions in this book illustrate the scienti?c advances that are going on in cotton and the impact they continue to deliver for all cotton growers. Twelve percent of the global cotton area is now under biotech products at 15. 5 million ha. The primary bene?ts from using genetically engineered cotton include reduced insecticide use, lower production costs, improved yields, lower farming risks, and increased opportunities to grow cotton in areas of severe pest infestation.
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."
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.
view than its own proper males should fecundate each blossom." ANDREW KNIGHT Philosophical Transactions, 1799 Pollination mechanisms and reproduction have a decisive bearing upon rational procedures in plant breeding and crop production. This book intends to furnish' under one cover an integrated botanical, genetical and breeding-methodologi cal treatment of the reproductive biology of spermatophytes mainly angiosperms; it is based on an advanced topical course in plant breeding taught at the Hebrew University of Jerusa lem. We have tried to present a coverage which is concise, but as comprehensive as possible, of the pollination mechanism and modes of reproduction of higher plants, and to illustrate topics, whenever practicable, by examples from cultivated plants. Nevertheless, some relevant publications may have escaped our attention or may not be mentioned because of various limitations. The book is organized into three parts. The first part starts with an evaluation of the significance of the different pollination mechanisms for plant breeding and crop produc tion, describes modes of reproduction in higher plants and discusses ecology and dynamics of pollination. The second part is devoted to crops propagated by self pollination and describes specific breeding procedures for such crops. The third part details sexual reproduction in higher plants and handles three mechanisms involved in the prevention of self pollination and their utilization in plant breeding: sex expres sion, incompatibility, and male sterility."
Dr Samuel Johnson, that famous eighteenth century lexicographer, said of oats 'A grain which in England is generally given to horses but in Scotland supports the people'. And presumably it was a Scotsman who riposted 'But what people and what horses ' That exchange encapsulates much of the history and role of oats - a cereal, once important as human food in parts of northern Europe but latterly used mainly as animal feed, especially favoured for horses. Although no longer a major food anywhere, oats still have a special and favoured niche in the cuisine of people living in the cooler and wetter regions of some parts of northern Europe. However, there is currently a resurgence of interest in the crop, because there is now considerable scientific evidence to support the view of Scotsmen who never doubted its dietary value. This book - very much an international effort, carefully orchestrated by Robert Welch - traces the origin, history and scientific progress which forms a sound basis for any further crop improvement and for broadening the utilization and marketing of oat products. Should rational consider ations lead to an increase in the importance of this cereal, I, for one, would be glad since I believe the rural landscape is the poorer for the increased rarity of golden fields of rippling oats which I used to be involved in harvesting."
Secondary pollen presentation is presentation of pollen to vectors by structures other than anthers, either passively or via a specialized protection and delivery system. The main part of the book describes secondary pollen presentation genus-by-genus in 25 families. The subject has never been extensively reviewed, although secondary pollen presentation occurs in the largest family of flowering plants, the Asteraceae (Compositae), and a large family of great economic importance, the Leguminosae. Now material from the scattered literature is brought together and supplemented with original observations. Many species are illustrated and each family is individually discussed. The last two chapters provide an overview of the whole topic. All the main functions that secondary pollen presentation may perform can be carried out in other plants without it. It is concluded from this that the evolution of secondary pollen presentation has been subject to constraint and canalization. The floral biology of most plants with secondary pollen presentation has not been adequately studied. Appendix 1 points to a wide range of topics on which research at various technical and academic levels is needed. The book should also become a reference work for morphologists, systematists, and floral ecologists.
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.
Genome Mapping and Molecular Breeding in Plants presents the current status of the elucidation and improvement of plant genomes of economic interest. The focus is on genetic and physical mapping, positioning, cloning, monitoring of desirable genes by molecular breeding and the most recent advances in genomics. The series comprises seven volumes: Cereals and Millets; Oilseeds; Pulses, Sugar and Tuber Crops; Fruits and Nuts; Vegetables; Technical Crops; and Forest Trees. Technical Crops includes plants of great agricultural importance. One chapter is devoted to cotton, the most important fiber crop on which significant progress in molecular genetic research has been made. Reviews on oil palm, coffee, tea, cocoa and rubber describe traditional breeding and preliminary molecular results. Chapters on forage crops, ornamentals, and medicinal and aromatic plants each cover a large number of crops and may serve as road maps for further molecular research.
The present book provides a comprehensive overview of our current knowledge on plastid biogenesis, plastid-nuclear communication, and the regulation of plastid gene expression at all levels. It also assesses the state-of-the-art in key technologies, such as proteomics and chloroplast transformation. Written by recognized experts in the field, the book further covers crucial post-translational processes in plastid biogenesis and function, including protein processing.
The adv antages of those systems are counterbalanced by some important dis- vantages. For one, in heterotrophic and mixotrophic systems high concentrations of organic ingredients are required in the nutrient medium (particularly sugar at 2% or more), associated with a high risk of microbial contamination. How, and to which extent this can be avoided will be dealt with in Chapter 3. Other disadvantages are the difficulties and limitations of extrapolating results based on tissue or cell c- tures, to interpreting phenomena occurring in an intact plant during its development. It has always to be kept in mind that tissue cultures are only model systems, with all positive and negative characteristics inherent of such experimental setups. To be realistic, a direct duplication of in situ conditions in tissue culture systems is still not possible even today in the 21st century, and probably never will be. The organization of the genetic system and of basic cell structures is, however, essentially the same, and therefore tissue cultures of higher plants should be better suited as model s- tems than, e.g., cultures of algae, often employed as model systems in physiological or biochemical investigations. The domain cell and tissue culture is rather broad, and necessarily unspecif ic. In terms of practical aspects, basically five areas can be distinguished (see Figs. 1.1, 1.2 ), which here shall be briefly surveyed before being discussed later at length.
Grasses are a principal source of food for mankind and play an important role in stabilizing the land surface of much of the globe. Understanding seed dormancy in the Gramineae is therefore of considerable significance to world agriculture and global ecology. This book provides a comprehensive review of the occurrence and explanation of seed dormancy in grasses. 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. Essential reading for all those who need to understand the mechanisms of seed dormancy, this book will be a valuable text for advanced students and professionals in plant physiology, crop science, plant breeding and agronomy.
The stone fruits, including peaches, apricots, almonds, plums and cherries, have been bred and grown for thousands of years and today are significant agricultural crops in many local economies worldwide providing important components to healthy diets. This volume, comprising 14 chapters authored by 37 scientists from 7 countries, presents a comprehensive commentary on classical genetics and breeding; molecular mapping and breeding of agronomic traits; cloning of genes of interest; recent advances on 'omics' sciences including structural and functional genomics, proteomics and metabolomics with an enumeration on the whole genome sequencing of the model fruit plant peach; and application of bioinformatic strategies and tools for stone fruit research.
The main theme of the book is sustainable disease management in a European context. Some of the questions addressed are: How does society benefit from plant pathology research? How can new molecular approaches solve relevant problems in disease management? What other fields can we exploit in plant pathology research? What challenges are associated with free trade across the new borders? How can we contribute to solving problems of developing countries? How does plant pathology contribute to food quality and safety? How does globalization/internationalization affect teaching and extension in plant pathology?
This manual is intended for the practising chemist who has to do a job in analysing plant material. Therefore, the present manual only contains ready-to-hand procedures without any comment. The procedures described are only for inorganic components, which frequently occur in the plant. Most procedures are designed to give a total content value of the element under consideration, regardless of the chemical structure in which it occurs in the plant. We have chosen for a design in which all digestion procedures are described in one chapter, all extraction procedures in one chapter and all determination procedures in one chapter. As a consequence, one has to choose a suitable digestion method in combination with the intended determination technique; this has been indicated within each individual determination procedure. For determination of the elements, mainly spectrometric techniques are used here. Depending on the kind of element and the expected concentration level, the following methods are applied: flame atomic emission spectrometry (flame AES), flame atomic absorption spectrometry (flame AAS), inductively coupled plasma optical emission spectrometry (ICP-OES), electrothermal atomisation (graphite furnace) atomic absorption spectrometry (ETA-AAS), inductively coupled plasma mass spectrometry (ICP-MS), spectrophotometry and segmented flow analysis (SFA). Besides, potentiometry (ion selective electrodes (ISE)) and coulometry will be encountered. In many cases, more than one method is described to determine a component. This provides a reference, as well as an alternative in case of instrumental or analytical problems. |
