Achievements today in plant biotechnology have already surpassed all previous expectations. Plant biotechnology, integrated with classical breeding, is now on the verge of creating the evergreen revolution' to solve the world's envisaged tripled demand for food, agricultural commodities and natural products. New biotechnologies are being continuously adapted to agricultural practices, opening new vistas for plant utilization. Plant biotechnology is changing the plant scene in three major areas: (1) growth and development control (vegetative, generative and propagation), (2) protecting plants against the ever-increasing threats of abiotic and biotic stress, (3) expanding the horizons by producing specialty foods, biochemicals and pharmaceuticals. The potential for improving plant and animal productivity and their proper use in agriculture relies largely on newly-developed DNA biotechnology and molecular markers. These techniques enable the selection of successful genotypes, better isolation and cloning of favorable traits, and the creating of transgenic organisms of importance to agriculture. These areas were extensively discussed at the 9th international congress of the International Association of Plant Tissue Culture and Biotechnology, Plant Biotechnology and In Vitro Biology in the 21st Century', which was held in Jerusalem in June 1998. The present book of proceedings contains the variety of scientific achievements and techniques that were presented: Basic and Applied Aspects of Growth, Development and Differentiation; Genetic Manipulations: Transformation and Gene Expression, Hybridization, Haploidization and Mutagenesis; Genetic Stability and Instability, Selection and Variability; Regulation of Primary and Secondary Metabolism; Model Systems: Cell Cycle, Transport and Signal Transduction; Biotechnology for Plant Protection: Abiotic and Biotic Stress; Biotechnology for Crop Improvement: Yield, Quality and Production of Valuable Substances; Novel Micropropagation Methods; New Markets and Commercial Applications; Intellectual Property Rights.

Fungi are an essential, fascinating and biotechnologically useful group of organisms with an incredible biotechnological potential for industrial exploitation. Knowledge of the world's fungal diversity and its use is still incomplete and fragmented. There are many opportunities to accelerate the process of filling knowledge gaps in these areas. The worldwide interest of the current era is to increase the tendency to use natural substances instead of synthetic ones. The increasing urge in society for natural ingredients has compelled biotechnologists to explore novel bioresources which can be exploited in industrial sector. Fungi, due to their unique attributes and broad range of their biological activities hold great promises for their application in biotechnology and industry. Fungi are an efficient source of antioxidants, enzymes, pigments, and many other secondary metabolites. The large scale production of fungal pigments and their utility provides natural coloration without creating harmful effects on entering the environment, a safer alternative use to synthetic colorants. The fungal enzymes can be exploited in wide range of industries such as food, detergent, paper, and also for removal toxic waste. This book will serve as valuable source of information as well as will provide new directions to researchers to conduct novel research in field of mycology. Volume 2 of "Industrially Important Fungi for Sustainable Development" provides an overview to understanding bioprospecting of fungal biomolecules and their industrial application for future sustainability. It encompasses current advanced knowledge of fungal communities and their potential biotechnological applications in industry and allied sectors. The book will be useful to scientists, researchers, and students of microbiology, biotechnology, agriculture, molecular biology, and environmental biology.

Charles E. Hess Department of Environmental Horticulture University of California Davis, CA 95616 Research in the biology of adventitious root formation has a special place in science. It provides an excellent forum in which to pursue fundamental research on the regulation of plant growth and development. At the same time the results of the research have been quickly applied by commercial plant propagators, agronomists, foresters and horticulturists (see the chapter by Kovar and Kuchenbuch, by Ritchie, and by Davies and coworkers in this volume). In an era when there is great interest in speeding technology transfer, the experiences gained in research in adventitious root formation may provide useful examples for other areas of science. Interaction between the fundamental and the applied have been and continue to be facilitated by the establishment, in 1951, of the Plant Propagators' Society, which has evolved into the International Plant Propagators' Society, with active programs in six regions around the world. It is a unique organization which brings together researchers in universities, botanical gardens and arboreta, and commercial plant propagators. In this synergistic environment new knowledge is rapidly transferred and new ideas for fundamental research evolve from the presentations and discussions by experienced plant propagators. In the past 50 years, based on research related to the biology of adventitious root formation, advances in plant propagation have been made on two major fronts.

Wheat breeders have achieved significant results over the last fifty years in research on mankind's one of the most important crops. Classical genetic and breeding methods, far broader international cooperation than was experienced in earlier periods, and improvements in agronomic techniques have led to previously unimaginable development in the utilisation of wheat for human consumption. The contribution of wheat researchers is particularly noteworthy since these results have been achieved at a time when the world population has grown extremely dynamically. Despite this demographic explosion, of a proportion never previously experienced, thousands of millions of people have been saved from starvation, thus avoiding unpredictable social consequences and situations irreconcilable with human dignity. Despite these developments in many regions of the world food supplies are still uncertain and the increase in the world's wheat production has not kept pace with the population increase during the last decade. Due to the evils of civilisation and the pollution of the environment there is a constant decline in the per capita area of land suitable for agricultural production. Based on population estimates for 2030, the present wheat yield of around 600 million tonnes will have to be increased to almost 1000 million tonnes if food supplies are to be maintained at the present level.

This edited book brings together comprehensive information on various aspects of the biofortification of staple crops. It addresses the present status of food and nutritional security and highlights the importance of micronutrients in human health, a historical account of biofortification, current approaches and challenges, crop-specific biofortification efforts and various breeding approaches, including conventional, and genomics enabled improvement. It also explains the efficacy of biofortification, bioavailability, and future thrust. It is an inclusive source of information on different aspects of micronutrients in crops of global importance. Malnutrition is a serious global issue, with millions of people being undernourished, several suffering from micronutrient deficiencies, and the adult population struggling with obesity. Despite significant economic progress, South Asia and Sub-Saharan Africa are still home to an undernourished population. Nutrition-related health problems are related to hidden hunger and are widespread in the developing world. Women and preschool children are more vulnerable. Even though global food production has increased manifolds, estimates indicate that over 60% of the world's population is deficient in essential micronutrients such as iron, zinc, iodine, and selenium, often causing health problems and developmental delays. Linking agricultural production with human nutrition and health is crucial for ensuring nutrition security. Much research has been carried out to assess genetic diversity related to micro-nutrients in staple crops, their bioavailability, and the efficacy of biofortified germplasm. Biofortified varieties developed in different crops through conventional breeding are being up-scaled for reducing the micronutrient deficiencies in other countries. This book is a ready reference for researchers, academicians, extension personnel, policymakers, students, and value chain stakeholders engaged in agriculture, nutrition, and health sectors promoting nutrition-sensitive diets.

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.

This book celebrates the dawn of the rye genomics era with concise, comprehensive, and accessible reviews on the current state of rye genomic research, written by experts in the field for students, researchers and growers. To most, rye is the key ingredient in a flavoursome bread or their favourite American whisky. To a farmer, rye is the remarkable grain that tolerates the harshest winters and the most unforgiving soils, befitting its legacy as the life-giving seed that fed the ancient civilisations of northern Eurasia. Since the mid-1900s, scientists have employed genetic approaches to better understand and utilize rye, but only since the technological advances of the mid-2010s has the possibility of addressing questions using rye genome assemblies become a reality. Alongside the secret of its unique survival abilities, rye genomics has accelerated research on a host of intriguing topics such as the complex history of rye's domestication by humans, the nature of genes that switch fertility on and off, the function and origin of accessory chromosomes, and the evolution of selfish DNA.

The rapid progress on somatic embryogenesis and its prospects for potential application to improving woody plants prompted us to edit this book initially in three volumes, and now an additional three more volumes. We were all convinced that such a treatise was needed and would be extremely useful to researchers and students. This volume 6 is dedicated to Prof. Harry Waris, Helsinki, Finland, who did pioneer work on somatic embryogenesis during the time when Prof. Steward and others were actively engaged in this area. His former student Prof. Liisa Simols, University of Helsinki, Finland, has written a dedication Harry Waris, a pioneer in somatic embryogenesis' to her teacher Prof. Waris. This volume is divided into three sections and contains a total of 26 chapters. Section A comprises seven chapters covering topics such as: Historical insights into some contemporary problems in somatic embryogenesis (SE); Thin cell layer for somatic embryogenesis induction in woody trees; SE in tropical fruit and forest trees; SE in fruit and forest arid trees; Status of SE in Indian forest trees; SE research in fruit trees in India; Applications of SE for the improvement of tropical fruit trees. Section B comprises 15 chapters, dealing with: SE in oil palm, hazelnut (Corylus avellana L.), pistachio (Pistacia vera L.), Araucaria angustifolia, Quercus suber, Aspidosperma polyneuron, Acacia senegal, Simmondsia chiensis, Cupressus sempervirens, pecan (Carya illinoinensis), rattan (Calamus spp.), tamarillo (Cyphomandra betacea, longan (Dimocarpus longan Lor.), Aegle marmelos, and Euonymus europaeus. Section C comprises three chapters related to cryo-storage of citrus, conifers and rubber. All the chaptershave been peer-reviewed and revised accordingly to improve the quality of the chapters. We are thankful to all: (a) contributory authors for their co-operation in submitting manuscripts in time, and (b) reviewers for spending their valuable time in reviewing the manuscripts.

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.

This book covers information on the economics; botany, taxonomy, and origin; germplasm resources; cytogenetics and nuclear DNA; genetic improvement efforts of scion cultivars; genetic and genomic improvement efforts of rootstocks; genetic and physical mapping; genomic resources; genome and epigenome; regulatory sequences; utility of whole-genome sequencing and gene editing in trait dissection; flowering and juvenility; cold hardiness and dormancy; fruit color development; fruit acidity and sugar content; metabolomics; biology and genomics of the microbiome; apple domestication; as well as other 'omics' opportunities and challenges for genetic improvement of the apple. The cultivated apple (Malus x domestica Borkh.) is one of the most important tree fruit crops of temperate regions of the world. It is widely cultivated and grown in North America, Europe, and Asia. The apple fruit is a highly desirable fruit due to its flavor, sugar and acid content, metabolites, aroma, as well as its overall texture and palatability. Furthermore, it is a rich source of important nutrients, including antioxidants, vitamins, and dietary fiber.

Agriculture's Ethical Horizon: Third Edition covers the changing environment in which practitioners of agriculture are challenged to produce food for the world. Fully revised and updated, the book encourages discussions on the moral questions that agriculture faces, including what goals should agricultural science pursue and how should practitioners address important ethical questions which are different and more complex than the dominating questions of production? The book presents the story of agriculture from the blood, sweat and tears era, to the present genetic era, including the paradox of agriculture. This book is ideal for agricultural students, practitioners and anyone who would like to understand the tremendous responsibility of agricultural production. It presents a foundation for the important discussions and decisions that will be necessary to support the future of agriculture.

Information is provided in a clear and systematic fashion, including data on relevant chemical families and pertinent chemical structures. Also included is a thesaurus of English, Latin and French plant species names as well as 655 references to the scientific literature.

This textbook contains the material for a course in the major principles of modelling crop growth processes. There is much more to crop growth than what is discussed in this textbook, but it provides a sound basis for further work and study in this field. Chapter by chapter the book leads the reader to different modelled aspects of crop growth, and at the end, the reader will have a good understanding of the Wageningen simulation model SUCROS for the potential production situation. By then, it will be much easier to find one's way through descriptions and listings of other models. Throughout the text, the study of the different topics is facilitated by exercises that support the course in a hands-on computer practical exercise. A very simple crop growth model, almost entirely based on radiation interception, is given first. This skeleton model is then expanded by submodels for respiration, carbon assimilation, plant development, and a more detailed model for radiation interception and reflection. Modelling of transpiration and the leaf energy balance is given by way of introduction. There are many listings of the submodels, written in the simulation language FST (FORTRAN Simulation Translator), as well as of SUCROS itself, together with plentiful comments. Some supporting theory is provided in the form of Appendices. The book is meant for students and scientists who would like to acquire a working knowledge of the technique of crop growth modelling.

This book reviews how the release of the citrus genome facilitates the investigation of ancestral species, the study of their complex biological features, and the genetic basis of agronomic traits of paramount importance for their sustainable cultivation. The first chapters discuss citrus origin and distribution, and the economic importance and varietal composition of the cultivated species, providing an overview of citrus and related genera genetic resources. The book then describes the role of traditional breeding techniques (for scion and rootstocks) as well as the potential of genomic breeding and innovative protocols for biotechnological approaches. The second part provides essential information on the genus Citrus, the attributes of pure citrus species, genetic admixtures, hybrids and citrus relatives, and on the horticultural classification of cultivated species, varieties and rootstocks. The third part then focuses on the different molecular mechanisms, covering various aspects of citrus biology, including the role of beneficial compounds of citrus fruits. In addition, it examines the molecular responses of citrus to abiotic stresses and to field and post-harvest diseases. Providing insights gained in recent years, it is a valuable guide for those who are interested in gene discovery, comparative genomics, molecular breeding and new breeding techniques. It is particularly useful for scientists, breeders and students at universities and public sector institutes involved in research for the citrus industry.

This book focuses on the importance and roles of seed microbiomes in sustainable agriculture by exploring the diversity of microbes vectored on and within seeds of both cultivated and non-cultivated plants. It provides essential insights into how seeds can be adapted to enhance microbiome vectoring, how damaged seed microbiomes can be assembled again and how seed microbiomes can be conserved. Plant seeds carry not only embryos and nutrients to fuel early seedling growth, but also microbes that modulate development, soil nutrient acquisition, and defense against pathogens and other stressors. Many of these microbes (bacteria and fungi) become endophytic, entering into the tissues of plants, and typically exist within plants without inducing negative effects. Although they have been reported in all plants examined to date, the extent to which plants rely on seed vectored microbiomes to enhance seedling competitiveness and survival is largely unappreciated. How microbes function to increase the fitness of seedlings is also little understood. The book is a unique and important resource for researchers and students in microbial ecology and biotechnology. Further, it appeals to applied academic and industrial agriculturists interested in increasing crop health and yield.

Maize is one of the most generally grown cereal crops at global level, followed by wheat and rice. Maize is the major crop in China both in terms of yield and acreage. In 2012, worldwide maize production was about 840 million tons. Maize has long been a staple food of most of the global population (particularly in South America and Africa) and a key nutrient resource for animal feed and for food industrial materials. Maize belts vary from the latitude 58° north to the latitude 40° south, and maize ripens every month of the year. Abiotic and biotic stresses are common in maize belts worldwide. Abiotic stresses (chiefly drought, salinity, and extreme temperatures), together with biotic stresses (primarily fungi, viruses, and pests), negatively affect maize growth, development, production and productivity. In the recent past, intense droughts, waterlogging, and extreme temperatures have relentlessly affected maize growth and yield. In China, 60% of the maize planting area is prone to drought, and the resultant yield loss is 20%–30% per year; in India, 25%–30% of the maize yield is lost as a result of waterlogging each year. The biotic stresses on maize are chiefly pathogens (fungal, bacterial, and viral), and the consequential syndromes, like ear/stalk rot, rough dwarf disease, and northern leaf blight, are widespread and result in grave damage. Roughly 10% of the global maize yield is lost each year as a result of biotic stresses. For example, the European corn borer [ECB, Ostrinianubilalis (Hübner)] causes yield losses of up to 2000 million dollars annually in the USA alone in the northern regions of China, the maize yield loss reaches 50% during years when maize badly affected by northern leaf blight. In addition, abiotic and biotic stresses time and again are present at the same time and rigorously influence maize production. To fulfill requirements of each maize-growing situation and to tackle the above mentions stresses in an effective way sensibly designed multidisciplinary strategy for developing suitable varieties for each of these stresses has been attempted during the last decade.  Genomics is a field of supreme significance for elucidating the genetic architecture of complex quantitative traits and characterizing germplasm collections to achieve precise and specific manipulation of desirable alleles/genes. Advances in genotyping technologies and high throughput phenomics approaches have resulted in accelerated crop improvement like genomic selection, speed breeding, particularly in maize.  Molecular breeding tools like collaborating all omics, has led to the development of maize genotypes having higher yields, improved quality and resilience to biotic and abiotic stresses. Through this book, we bring into one volume the various important aspects of maize improvement and the recent technological advances in development of maize genotypes with high yield, high quality and resilience to biotic and abiotic stresses
