This book provides in-depth insights into the regulatory frameworks of five countries and the EU concerning the regulation of genome edited plants. The country reports form the basis for a comparative analysis of the various national regulations governing genetically modified organisms (GMOs) in general and genome edited plants in particular, as well as the underlying regulatory approaches.The reports, which focus on the regulatory status quo of genome edited plants in Argentina, Australia, Canada, the EU, Japan and the USA, were written by distinguished experts following a uniform structure. On this basis, the legal frameworks are compared in order to foster a rational assessment of which approaches could be drawn upon to adjust, or to completely realign, the current EU regime for GMOs. In addition, a separate chapter identifies potential best practices for the regulation of plants derived from genome editing.

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).

Topics for the Beltsville Symposia are selected to highlight specific areas of research and science policy that are of concern to scientists in the Beltsville Area as well as to the general scientific community. Each sympo sium in the series is structured to provide a realistic appraisal of current findings, research progress, and relevant policy issues within the constraints established by the organizing committee. Thus, the presentations and dis cussions that have marked these symposia have had a strong appeal to the broad community of scientists. Knowledge of the diversity of living organisms is still quite limited. Since the time of Linnaeus, about 1.7 million species have been described. The actual number has been estimated between 5-50 million. Many species, land races, and strains are vanishing. Clearly, the world's scientific institutions are inadequately equipped to attain sufficient knowledge of a significant fraction of the diverse living forms. Also, efforts in the collection and preservation of germplasm of plants and animals urgently need to be strengthened. These mattes are critically important to future generations. This symposium addresses vital concerns of biotic diversity and germ plasm preservation from diverse perspectives. Many of the parts provide concrete recommendations for action, and they call attention to areas of research that must be pursued with intensity."

A Seminar in the EEC Programme of Coordination of Research on Plant Protein Improvement

Plant breeding has undergone a period of very rapid and significant development in recent years and the area of fruit breeding is no exception. This book provides a balanced, up-to-date and comprehensive account of the developments in the field of breeding tropical and subtropical fruits. It offers not only the theoretical and applied aspects of breedings fruits but also provides an authoritative manual of the conventional and new techniques used for increasing efficiency of crop improvement programmes. In specific chapters the book deals with crop taxonomy, genetic resources, floral biology, breeding objectives, inheritance patterns and information on new improved cultivars/hybrids.

The International Symposium on "Cellular and Molecular Aspects of Biosynthesis and Action of the Plant Hormone Ethylenc" ,vas held in Agen, France from August 31 st and September 4th, 1992. The planning and management of the scientific and social programme of the Conference were carried out jointly by the "Ethylene Research Group" of ENSAlIN"P (Toulouse) and Agropole Congres Service (Agen). Since the last meetings in Israel (1984) and in Belgium (1988), ethylene physiology has gone through a period of exciting progress due to new developments in cellular and molecular bioiogy. New methods and tools have been developed to better understand the role and functions of ethylene in fruit ripening, flower senescence, abscission, piant growth, and cell differentiation. Genes involved in ethylene biosynthesis have been characterized and transgenic plants with altered ethylene production have been generated. The feasibility of delaying fruit ripening or flower senescence by genetic manipulation is now demonstrated, thus opening new perspectives for the postharvest handling of plant products. Some progress has also been made on the understanding of ethylene action. However, much remains to be done in this area to elucidate the ethylene signal transduction pathway. Around 140 scientists from 20 countries attended the Symposium. They presented 47 oral reports and 40 poster demonstrations. All of them are published in these proceedings. It has been a pleasure for us to organize this important Symposium and to edit this book.

In 1980, a conference on tissue culture of fruit crops was held at Beltsville to summarize the current status of this technology and to stimulate interest in it among research scientists, students, and commercial producers in the U. S. Interest in that conference and the proceedings from it far exceeded the expectations of the organizing committee. Since that time, micropropagation of fruit crops in the U. S. has increased significantly, but still lags far behind applications to production of ornamental plants. Within the past two years, a number of new laboratories have been established and some of the existing laboratories have expanded to a size far larger than any previously anticipated. Creation of new laboratories capable of producing more than 400,000 plants per week will test the ingenuity of laboratory managers and the skills of marketing departments. In recent years, numerous symposia have been held on various aspects of biotechnology and genetic engineering. Although micro propagation is the key to providing large numbers of genetically engineered plants, it is a topic that has been relegated to a minor position, or ignored completely, at such meetings. Accordingly, the time seemed propitious for a conference devoted solely to all aspects of micropropagation as applicable to horticultural crops.

Plants have to manage a series of environmental stresses throughout their entire lifespan. Among these, abiotic stress is the most detrimental; one that is responsible for nearly 50% of crop yield reduction and appears to be a potential threat to global food security in coming decades. Plant growth and development reduces drastically due to adverse effects of abiotic stresses. It has been estimated that crop can exhibit only 30% of their genetic potentiality under abiotic stress condition. So, this is a fundamental need to understand the stress responses to facilitate breeders to develop stress resistant and stress tolerant cultivars along with good management practices to withstand abiotic stresses. Also, a holistic approach to understanding the molecular and biochemical interactions of plants is important to implement the knowledge of resistance mechanisms under abiotic stresses. Agronomic practices like selecting cultivars that is tolerant to wide range of climatic condition, planting date, irrigation scheduling, fertilizer management could be some of the effective short-term adaptive tools to fight against abiotic stresses. In addition, "system biology" and "omics approaches" in recent studies offer a long-term opportunity at the molecular level in dealing with abiotic stresses. The genetic approach, for example, selection and identification of major conditioning genes by linkage mapping and quantitative trait loci (QTL), production of mutant genes and transgenic introduction of novel genes, has imparted some tolerant characteristics in crop varieties from their wild ancestors. Recently research has revealed the interactions between micro-RNAs (miRNAs) and plant stress responses exposed to salinity, freezing stress and dehydration. Accordingly transgenic approaches to generate stress-tolerant plant are one of the most interesting researches to date. This book presents the recent development of agronomic and molecular approaches in conferring plant abiotic stress tolerance in an organized way. The present volume will be of great interest among research students and teaching community, and can also be used as reference material by professional researchers.

Recent studies have revealed remarkable complexity and diversity in orchid-pollinator relationships. These studies comprise a vast literature currently scattered in numerous, often obscure, journals and books. "The Pollination Biology of North American Orchids" brings together, for the first time, a comprehensive treatment of this information for all native and introduced North American orchids found north of Mexico and Florida. It provides detailed information on genetic compatibility, breeding systems, pollinators, pollination mechanisms, fruiting success, and limiting factors for each species. Distribution, habitat, and floral morphology are also summarized. In addition, detailed line drawings emphasize orchid reproductive organs and their adaptation to known pollinators.

This, the second of two volumes, treatsthe subfamily Orchidoideae with the tribe Cranichideae. This is followed by examination of the seven North American tribes of subfamily Epidendroideae and the single North American tribe of subfamily Vanilloideae.

"The Pollination Biology of North American Orchids" will be of interest to both regional and international audiences including: Researchers and students in this field of study who are currently required to search through the scattered literature to obtain the information gathered here.Researchers and students in related fields with an interest in the co-evolution of plants and insects.Conservation specialists who need to understand both the details of orchid reproduction and the identity of primary pollinators in order to properly manage the land for both.Orchid breeders who require accurate and current information on orchid breeding systems. General readers with an interest in orchid biology.

This book contains complete information on Capsicum genetic resources, diversity, evolution, history and advances in capsicum improvement from classical breeding to whole genome sequencing, genomics, databases and its impact on next generation pepper breeding. Capsicum is one of the most important Solanaceae crops grown worldwide as vegetables and spices. Due to its high economic value and to meet the demands of enormous population growth amid biotic and abiotic stresses, there has been an ongoing breeding program utilizing available genetic resources with desired traits to increase the sustainable productivity of this crop for several decades. However, the precision breeding of this crop for desired traits only started with the advent of molecular markers. The recent advances in high-throughput genome sequencing technologies helped in the quick decoding of transcriptome, epigenome, nuclear and organeller genomes, thereby enhancing our understanding of the structure and function of the Capsicum genome, and helping in genomics assisted breeding. These advanced technologies coupled with conventional mapping have greatly contributed towards dissection and manipulation of economically important traits more precisely and made less time consuming.

This is the first book on the genome of Salvia miltiorrhiza, summarizing the research advances in the molecular mapping, whole genome sequencing, chloroplast and mitochondria genomes, epigenetics, transcriptomics and functional genomics of this emerging model plant with great economic and medicinal value. It also describes its distribution, taxonomy and morphology and provides useful information on its cultivation and breeding. Further, it highlights the biosynthetic pathways of tanshinones and phenolic acids - two main classes of bioactive components produced in this plant species - and reviews and discusses the technology of hairy root induction, tissue culture and genetic transformation of S. miltiorrhiza. The book is a valuable resource for students, teachers and researchers in academia and industry interested in medicinal plants and pharmacy.

These Proceedings evolved from the OECD Co-operative Research Programme workshop on "Potential ecological impact of transgenic plants expressing viral sequencies," held at the Agricultural Biotechnology Center in Godollo, Hungary on 24-26 April 1997.

The quality of human life has been maintained and enhanced for generations by the use of trees and their products. In recent years, ever rising human population growth has put a tremendous pressure on trees and tree products; growing awareness of the potential of previously unexploited tree resources; and environmental pollution have both accelerated the development of new technologies for tree propagation, breeding and improvement. Biotechnology of trees may be the answer to solve the problems which can not be solved by conventional breeding methods. The combination of biotechnology and conventional methods such as plant propagation and breeding could become a novel approach to improving and multiplying a large number of the trees and woody plants. So far, plant tissue culture technology has largely been exploited by commercial companies in propagation of ornamentals, especially foliage house plants. Generally, tissue culture of woody plants has been recalcitrant. However, limited success has been achieved in tissue culture of angiosperm and gymnosperm woody plants. A number of recent reports on somatic embryogenesis in woody plants such as Norway spruce (Picea abies), Loblolly pine (Pinus taeda), Sandalwood (Santalum album), Citrus and mango (Mangifera indica), offer a ray of hope for inexpensive clonal propagation for large-scale production of plants or 'emblings' or somatic seedlings; protoplast work; cryopreservation; genetic transformation; and synthetic or artificial or manufactured seed production.

This book offers effective, low-cost and user-friendly protocols for the pre-field selection of salt-tolerant mutants in cereal crops. It presents simple methods for measuring soil salinity, including soil sampling and the analysis of water-soluble salts, and describes a detailed, but simple, screening test for salt tolerance in rice, wheat and barley seedlings, which uses hydroponics. The protocols are devised for use by plant breeders and can be easily accommodated into breeding practice.

Soil salinity is a key abiotic-stress and poses serious threats to crop yields and quality of produce. Owing to the underlying complexity, conventional breeding programs have met with limited success. Even genetic engineering approaches, via transferring/overexpressing a single 'direct action gene' per event did not yield optimal results. Nevertheless, the biotechnological advents in last decade coupled with the availability of genomic sequences of major crops and model plants have opened new vistas for understanding salinity-responses and improving salinity tolerance in important glycophytic crops. Our goal is to summarize these findings for those who wish to understand and target the molecular mechanisms for producing salt-tolerant and high-yielding crops. Through this 2-volume book series, we critically assess the potential venues for imparting salt stress tolerance to major crops in the post-genomic era. Accordingly, perspectives on improving crop salinity tolerance by targeting the sensory, ion-transport and signaling mechanisms were presented in Volume 1. Volume 2 now focuses on the potency of post-genomic era tools that include RNAi, genomic intervention, genome editing and systems biology approaches for producing salt tolerant crops.

The ability of plants to exchange RNA molecules and transcription factors between cells and tissues is a relatively recent discovery. However, all areas of research such as plant development, metabolism, and plant pathogen interactions now realize the importance of this phenomenon. In this book, experts from the field of intercellular transport deal with various aspects on intercellular transport of viruses and plant endogenous macromolecules such as transcription factors, small silencing-induced and micro RNAs, and other RNAs and their function as signals. The aim of the book is to provide the basic information on the cell-to-cell transport mechanism and to give an overview of the current knowledge of this relatively new field of research. To quote the words of W.J. Lucas "...pioneering discoveries in this field of cell-to-cell and long-distance signaling should certainly entice talented young scholars to join this frontier area of plant biology" . He is certainly right as we got only a first glimpse on the cellular factors regulating intercellular transport and the functional diversity of the ever-increasing number of proteins and RNA molecules found to move between cells.

The improvement of crop species has been a basic pursuit since cultivation began thousands of years ago. To feed an ever increasing world population will require a great increase in food production. Wheat, corn, rice, potato and few others are expected to lead as the most important crops in the world. Enormous efforts are made all over the world to document as well as use these resources. Everybody knows that the introgression of genes in wheat provided the foundation for the "Green Revolution". Later also demonstrated the great impact that genetic resources have on production. Several factors are contributing to high plant performance under different environmental conditions, therefore an effective and complementary use of all available technological tools and resources is needed to meet the challenge.

Artemisinin, a sesquiterpene lactone originally extracted from the medicinal plant Artemisia annua L., is an effective antimalarial agent, particularly for multi-drug resistant and cerebral malaria. However, the concentration of artemisinin in the plant is very low. Because the chemical synthesis of artemisinin is complicated and not economically feasible in view of the poor yield of the drug, the intact plant remains the only viable source of artemisinin production. Therefore, it is necessary to increase the concentration of artemisinin in A. annua to reduce the cost of artemisinin based antimalarial drugs. Plant scientists have focused their efforts on A. annua for a higher artemisinin crop yield. With the present volume, we are bringing together the research which is being done on this plant throughout the world and future possibilities for scientists and researchers who want to work on it.

This book presents up-to-date information on foxtail millet genomics, with a particular focus on its agronomic importance, genome architecture, marker development, evolutionary and diversity studies, comparative genomics and stress biology. The topics discussed have the potential to open up a new era of crop improvement in foxtail millet and other related grass species. Foxtail millet (Setaria italica L.) is the oldest domesticated crop in the world (domesticated >8700 years ago) and it has been extensively grown in the semi-arid regions of Asia, Europe and the Americas as a food and fodder crop ever since. Further, as a C4 crop with close genetic relatedness to several biofuel grasses, foxtail millet has been promoted as a model plant. In view of its importance, the US Department of Energy Joint Genome Institute and Beijing Genomics Institute have independently sequenced the genome of foxtail millet. The availability of the draft genome sequence has advanced the genomics and genetics of this important crop, resulting in the development of large-scale genome-wide molecular markers and demonstration of their utility in genomics-assisted breeding, as well as the identification of the molecular and biological roles of several stress-responsive gene families in connection with abiotic stress tolerance. In addition, several open access databases have been developed to make these resources for crop improvement through structural and functional genomics widely available.

The International Centre for Advanced Mediterranean Agronomic Studies (CIHEAM), established in 1962, is an intergovernmental organization of four teen countries: Albania, Algeria, Egypt, France, Greece, Italy, Lebanon, Malta, Morocco, Portugal, Spain, Tunisia, Turkey and Yugoslavia. Four institutes (Bari, Italy; Chania, Greece; Montpellier, France and Zaragoza, Spain) provide post-graduate education at the Master of Science level. CIHEAM promotes research networks on Mediterranean agricultural priorities, supports the organization of specialized education in member countries, holds seminars and workshops bringing together technologists and scientists involved in Mediterranean agriculture and regularly produces diverse publications including the series 'Options Mediterraneennes'. Through these activities, CIHEAM promotes North/South dialogue and international co-operation for agricultural development in the Mediterranean region. Plant breeding is, since 1982, one of the fields in which CIHEAM is con ducting a programme of training and promotion of research, through its Mediterranean Agronomic Institute of Zaragoza. The programme includes a one-year advanced specialization course, a series of two-week courses for professionals, and support for collaborative research activities in Mediterranean-relevant species. Many of these activities are organized in col laboration with national and international institutions. The publication in 1993 of Plant Breeding. Principles and Prospects, which ini tiated the Chapman & Hall's Plant Breeding Series, has become an important feature of CIHEAM's plant breeding programme. We are now pleased to add a further volume to that series: the present book, Statistical Methods for Plant Variety Evaluation."

This is the fourth major publication on Vicia faba reporting proceedings of seminars organised through the Commission of the European Communities in the context of the E.E.C. Common Research Programme on Plant Protein Improvement. The previous three volumes report proceedings from the seminar in Sari in 1978 (Some current research on Vicia faba in Western Europe), and from Cambridge in 1979 (Vicia faba : Feeding value, processing and viruses) and in Wageningen in 1980 (Vicia faba : Physiology and Breeding). The theme of this seminar, held at the University of Nottingham from 14th to 16th September 1983 was selected to examine current research on agronomy, physiology, plant breeding and nutrition. 84 delegates from 15 European countries attended. Throughout the seminar there was a spirit of friendliness and co-operation. Everyone seemed dedicated to doing real justice to the faba bean crop. The organisation of this seminar would not have been possible without the help of my secretary, Mrs. Jeanne Rodwell who undertook most of the administrative and secretarial work. P.D. Hebblethwaite COMPONENTS OF THE YIELD AND YIELD OF VICIA FABA Ph. Plancquaert, J.L. Raphalen Institut Technique des Cereales et des Fourrages 8 Avenue du President Wilson, 75116 Paris, France. ABSTRACT Preliminary experiments have indicated the main factors affecting the yield of winter (6 trials) and spring faba beans (5 trials) : information is presented on the development of pods and flowers, yield and yield components and grain protein content at different locations in France.

This book provides detailed and comprehensive information on oxidative damage caused by stresses in plants with especial reference to the metabolism of reactive oxygen species (ROS). In plants, as in all aerobic organisms, ROS are common by-products formed by the inevitable leakage of electrons onto O2 from the electron transport activities located in chloroplasts, mitochondria, peroxisomes and in plasma membranes or as a consequence of various metabolic pathways confined in different cellular loci. Environmental stresses such as heat, cold, drought, salinity, heavy-metal toxicity, ozone and ultraviolet radiation as well as pathogens/contagion attack lead to enhanced generation of ROS in plants due to disruption of cellular homeostasis. ROS play a dual role in plants; at low concentrations they act as signaling molecules that facilitate several responses in plant cells, including those promoted by biotic and abiotic agents. In divergence, at high levels they cause damage to cellular constituents triggering oxidative stress. In either case, small antioxidant molecules and enzymes modulate the action of these ambivalent species.
