For centuries orchids have been among the most popular of plant families, with thousands of species and hybrids cultivated worldwide for the diversity, beauty, and intricacy of their flowers.
The Genera Orchidacearum series represents a robust and natural classification of the orchids, something that has eluded plant scientists and orchid enthusiasts for years. The editors, who are all distinguished orchid specialists, incorporate a wealth of new DNA data into a truly phylogenetic classification, identifying the areas and taxa that merit additional work. To this end, they have invited several international specialists to contribute in their particular areas of expertise. Each volume provides comprehensive coverage of one or two orchid subfamilies and the series as a whole will be an indispensable reference tool for scientists, orchid breeders and growers.
Orchidaceae is the largest monocotyledon family and perhaps the largest plant family in terms of number of species, approximately 25,000. However, for a variety of reasons it remains one of the least understood. The fossil record is poor, and active research has been relatively scarce until recent years, in part because of the sheer size and cosmopolitan distribution of the family.
The fifth volume treats 186 genera in tribe Cymbidieae of the largest subfamily, Epidendroideae, including some of the showiest orchids often used in hybridizing. Comprehensive treatments are provided for each genus, which include complete nomenclature, description, distribution (with map), anatomy, palynology, cytogenetics, phytochemistry, phylogenetics, pollination, ecology, and economic uses. Cultivation notes are included for those genera known to be in hobbyist collections. Genera are beautifully illustrated with line drawings and colour photographs.

During the past decade, there has been tremendous progress in maize biotechnology. This volume provides an overview of our current knowledge of maize molecular genetics, how it is being used to improve the crop, and future possibilities for crop enhancement. Several chapters deal with genetically engineered traits that are currently, or soon will be, in commercial production. Technical approaches for introducing novel genes into the maize genome, the regeneration of plants from transformed cells, and the creation of transgenic lines for field production are covered. Further, the authors describe how molecular genetic techniques are being used to identify genes and characterize their function, and how these procedures are utilized to develop elite maize germplasm. Moreover, molecular biology and physiological studies of corn as a basis for the improvement of its nutritional and food-making properties are included. Finally, the growing use of corn as biomass for energy production is discussed.

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

Christel Ross investigates whether evolutionary changes by plant breeding are an important factor for the invasion success of Mahonia aquifolium in Germany. Her findings show that invasive populations differ from native populations in quantitative-genetic traits and molecular markers, whereas their genetic diversity is similar. She postulates that these evolutionary changes are rather a result of plant breeding, which includes interspecific hybridisation, than the result of a genetic bottleneck or the releases from specialist herbivores.

Molecular farming is a biotechnological approach that includes the genetic adjustment of agricultural products to create proteins and chemicals for profitable and pharmaceutical purposes. Plant molecular farming describes the manufacture of recombinant proteins and other biologically active product in plants. This approach depends on a genetic transformation of plants that can be accomplished by the methods of stable gene transfer, such as gene transfer to nuclei and chloroplasts, and unstable transfer methods like viral vectors. The requirement for recombinant proteins in terms of quality, quantity, and diversity is increasing exponentially This demand is traditionally met by recombinant protein construction technologies and the engineering of orthodox expression systems based on bacteria or mammalian cell cultures. However, majority of developing countries cannot afford the high costs of medicine derived from such existing methods. Hence, we need to produce not only the new drugs but also the cheaper versions of those already present in the market. Plant molecular farming is considered as a cost-effective technology that has grown and advanced tremendously over the past two decades. This book summarizes the advances and challenges of plant molecular farming for all those who are working on or have an interest in this rapidly emerging area of research.

In a new series in plant conservation sponsored by the World Wide Fund for Nature (WWF), this book is a practical guide to a subject of increasing concern to the conservation biologist. As with each of the books in the series, this book aims to give an authoritative guide to the subject in a clear, jargon-free style. It should therefore not only be of interest to the academic biologist interested in the phenomenon of invasion, but also to government and non-governmental personnel involved in the decision-making process needed as a result of the problems encountered with invasive species. Case-studies highlight specific problems from a wide range of countries, including North America, South and Central America, Africa, Australasia, South and South East Asia, Europe, the Pacific and Atlantic Islands and Indonesia. The book contains an appendix with a list of invasive species and their countries of origin. A bibliography contains reference to all cited articles and books. This book should be of interest to conservation biologists, economic botanists, ethnobotanists, plant ecologists, agriculturalists, those interested in development problems, geographers, environmental scientists, ecotourists and "green" lay people.

This book presents the life science experiments in a space microgravity environment conducted on board the SJ-10 recoverable satellite, which was launched on April 6th 2016 and recovered on April 18th 2016. It covers 10 scientific projects in radiation biology, gravitational biology and biotechnology that were selected from ~100 proposals from various institutions in China and around the world. Primarily exploring the rhythm of life in a space microgravity environment, all of the experiments - conducted on nine payloads of the SJ-10 satellite - have never been previously conducted in the respective fields. In addition, the book provides extensive information on the mission's execution, data collection, and scientific outcomes.

Plant hormones play a crucial role in controlling the way in which plants growand develop. Whilemetabolism providesthepowerand buildingblocks for plant life, it is the hormones that regulate the speed of growth of the individual parts and integrate these parts to produce the form that we recognize as a plant. In addition, theyplayacontrolling role inthe processes of reproduction. This book is a description ofthese natural chemicals: how they are synthesizedand metabolized; howthey work; whatwe knowoftheir molecular biology; how we measure them; and a description ofsome ofthe roles they play in regulating plant growth and development. Emphasis has also been placed on the new findings on plant hormones deriving from the expanding use ofmolecular biology as a tool to understand these fascinating regulatory molecules. Even at the present time, when the role of genes in regulating all aspects of growth and development is considered of prime importance, it is still clear that the path of development is nonetheless very much under hormonal control, either via changes in hormone levels in response to changes in gene transcription, or with the hormones themselves as regulators ofgene transcription. This is not a conference proceedings, but a selected collection ofnewly written, integrated, illustrated reviews describing our knowledge of plant hormones, and the experimental work that is the foundation of this knowledge.

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 supplement, containing six chapters, is the first in a series of important works designed to be integrated into the text of the Plant Tissue Culture Manual to maintain it as a valuable source of laboratory methodology

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 germination of seeds is a magical event, in which a pinch of dust-like material may give rise to all the power and the beauty of the growing plant. The mechanisms of seed dormancy, of the breaking of seed dormancy and of germination itself continue to remain shrouded in mystery, despite the best efforts of plant scientists. Perhaps we are getting there, but very slowly. This book considers germination and dormancy from the point of view of plant physiology. Plant physiologists attempt to understand the relation ship between plant form and function and to explain, in physical and chemical terms, plant growth and development. The place of germination and dormancy in plant ecophysiology is taken into account with attempts to understand the seed in its .environment, whether the environment be natural, semi-natural or wholly artificial. In due course plant scientists hope to develop a precise understanding of germination and dormancy in cellular and molecular terms, and therefore there is some biochemistry in this book. Biochemists who wish to learn something about seeds should find this book useful."

This open access book presents simple, robust pre-field screening protocols that allow plant breeders to screen for enhanced tolerance to heat stress in rice. Two critical heat-sensitive stages in the lifecycle of the rice crop are targeted - the seedling and flowering stages - with screening based on simple phenotypic responses. The protocols are based on the use of a hydroponics system and/or pot experiments in a glasshouse in combination with a controlled growth chamber where the heat stress treatment is applied. The protocols are designed to be effective, simple, reproducible and user-friendly. The protocols will enable plant breeders to effectively reduce the number of plants from a few thousands to less than 100 candidate individual mutants or lines in a greenhouse/growth chamber, which can then be used for further testing and validation in the field conditions. The methods can also be used to classify rice genotypes according to their heat tolerance characteristics. Thus, different types of heat stress tolerance mechanisms can be identified, presenting opportunities for pyramiding different (mutant) sources of heat stress tolerance.

The Sixth International Congress on Photosynthesis took place from 1 to 6 August 1983, on the Campus of the "Vrije Universiteit Brussel", in Brussels, Belgium. These Proceedings contain most of the scientific contributions offered during the Congress. The Brussels Congress was the largest thus far held in the series of International Congresses on Photosynthesis. It counted over 1100 active participants. The organizers tried to minimize the disadvantages of such a large size by making maximum use of the facili ties available on a university campus. Most contributions were offered in the form of posters which were displayed in a substantial number of classrooms. The discussion sessions, twice a day, four or five in parallel, took place in lecture rooms in the very vicinity of these classrooms. In this way it was attempted to generate the atmosphere of a small meeting. The unity of the subject Photosynthesis was preserved in the ten plenary lectures, organ~sed in such a way that a general overview of two diverse topics was given every day. In addition, there were the five times four parallel symposia dealing with some six teen general topics. Every editor of proceedings of a congress is faced with the problem of editing and arranging the contributions, a problem compounded by the wide diversity and the large number of the 753 manuscripts.

This book provides a comprehensive overview of carotenoid biosynthesis by different organisms, including bacteria, archaea, fungi, arthropods, and plants.

With contributions from leading experts in biology, biotechnology, and chemistry of carotenoid research, this volume discusses the biological functions of carotenoids such as astaxanthin, -cryptoxanthin, and fucoxanthin, in addition to paprika carotenoids, capsanthin, and capsorubin. It also reveals the technologies behind the commercial production of some functional carotenoids. The book is targeted for academic and industrial readers in biology, biotechnology, nutrient physiology and related fields.

The population of the world continues to increase at an alarming rate. The trouble linked with overpopulation ranges from food and water scarcity to inadequacy of space for organisms. Overpopulation is also linked with several other demographic hazards, for instance, population blooming will not only result in exhaustion of natural repositories, but it will also induce intense pressure on the world economy. Today nanotechnology is often discussed as a key discipline of research but it has positive and negative aspects. Also, due to industrialization and ever-increasing population, nano-pollution has been an emerging topic among scientists for investigation and debate. Nanotechnology measures any substance on a macromolecular scale, molecular scale, and even atomic scale. More importantly, nanotechnology deals with the manipulation and control of any matter at the dimension of a single nanometer. Nanotechnology and nanoparticles (NPs) play important roles in sustainable development and environmental challenges as well. NPs possess both harmful and beneficial effects on the environment and its harboring components, such as microbes, plants, and humans. There are many beneficial impacts exerted by nanoparticles, however, including their role in the management of waste water and soil treatment, cosmetics, food packaging, agriculture, biomedicines, pharmaceuticals, renewable energies, and environmental remedies. Conversely, NPs also show some toxic effects on microbes, plants, as well as human beings. It has been reported that use of nanotechnological products leads to the more accumulation of NPs in soil and aquatic ecosystems, which may be detrimental for living organisms. Further, toxic effects of NPs on microbes, invertebrates, and aquatic organisms including algae, has been measured. Scientists have also reported on the negative impact of NPs on plants by discussing the delivery of NPs in plants. Additionally, scientists have also showed that NPs interact with plant cells, which results in alterations in growth, biological function, gene expression, and development. Thus, there has been much investigated and reported on NPs and plant interactions in the last decade. This book discusses the most recent work on NPs and plant interaction, which should be useful for scientists working in nanotechnology across a wide variety of disciplines.

The range of nanomaterial applications has expanded recently from catalysis, electronics, and filtration to therapeutics, diagnostics, agriculture, and food because of unique properties and potentials of different nanoparticles and nanomaterials. Research shows that these exquisite particles can interact with an organism at the cellular, physiological, biochemical, and molecular levels. However, our knowledge of how they affect these changes, selectively or generally, in diverse organism or ecosystems is very limited and far from satisfactory. Data indicate that the biological function largely depends on the shape, size, and surface characteristics of the nanoparticles used besides life cycle stages of an organism. Therefore, this compilation will focus on the body of work carried out by distinguished investigators using diverse nanomaterials and plant and animal species. This book includes specific case studies as well as general review articles highlighting aspects of multilayered interactions, and targets not only research and academic scholars but also the concerned industry and policy makers as well.

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.

This book is open access under a CC BY 4.0 license. By 2050, human population is expected to reach 9.7 billion. The demand for increased food production needs to be met from ever reducing resources of land, water and other environmental constraints. Rice remains the staple food source for a majority of the global populations, but especially in Asia where ninety percent of rice is grown and consumed. Climate change continues to impose abiotic and biotic stresses that curtail rice quality and yields. Researchers have been challenged to provide innovative solutions to maintain, or even increase, rice production. Amongst them, the 'green super rice' breeding strategy has been successful for leading the development and release of multiple abiotic and biotic stress tolerant rice varieties. Recent advances in plant molecular biology and biotechnologies have led to the identification of stress responsive genes and signaling pathways, which open up new paradigms to augment rice productivity. Accordingly, transcription factors, protein kinases and enzymes for generating protective metabolites and proteins all contribute to an intricate network of events that guard and maintain cellular integrity. In addition, various quantitative trait loci associated with elevated stress tolerance have been cloned, resulting in the detection of novel genes for biotic and abiotic stress resistance. Mechanistic understanding of the genetic basis of traits, such as N and P use, is allowing rice researchers to engineer nutrient-efficient rice varieties, which would result in higher yields with lower inputs. Likewise, the research in micronutrients biosynthesis opens doors to genetic engineering of metabolic pathways to enhance micronutrients production. With third generation sequencing techniques on the horizon, exciting progress can be expected to vastly improve molecular markers for gene-trait associations forecast with increasing accuracy. This book emphasizes on the areas of rice science that attempt to overcome the foremost limitations in rice production. Our intention is to highlight research advances in the fields of physiology, molecular breeding and genetics, with a special focus on increasing productivity, improving biotic and abiotic stress tolerance and nutritional quality of rice.

Plants, being sessile and autotrophic in nature, must cope with challenging environmental aberrations and therefore have evolved various responsive or defensive mechanisms including stress sensing mechanisms, antioxidant system, signaling pathways, secondary metabolites biosynthesis, and other defensive pathways among which accumulation of osmolytes or osmo-protectants is an important phenomenon. Osmolytes with organic chemical nature termed as compatible solutes are highly soluble compounds with no net charge at physiological pH and nontoxic at higher concentrations to plant cells. Compatible solutes in plants involve compounds like proline, glycine betaine, polyamines, trehalose, raffinose family oligosaccharides, fructans, gamma aminobutyric acid (GABA), and sugar alcohols playing structural, physiological, biochemical, and signaling roles during normal plant growth and development. The current and sustaining problems of climate change and increasing world population has challenged global food security. To feed more than 9 billion, the estimated population by 2050, the yield of major crops needs to be increased 1.1-1.3% per year, which is mainly restricted by the yield ceiling. A major factor limiting the crop yield is the changing global environmental conditions which includes drought, salinity and extreme temperatures and are responsible for a reduction of crop yield in almost all the crop plants. This condition may worsen with a decrease in agricultural land or the loss of potential crop yields by 70%. Therefore, it is a challenging task for agricultural scientists to develop tolerant/resistant varieties against abiotic stresses. The development of stress tolerant plant varieties through conventional breeding is very slow due to complex multigene traits. Engineering compatible solutes biosynthesis by deciphering the mechanism behind the abiotic tolerance or accumulation in plants cell is a potential emerging strategy to mitigate adverse effects of abiotic stresses and increase global crop production. However, detailed information on compatible solutes, including their sensing/signaling, biosynthesis, regulatory components, underlying biochemical mechanisms, crosstalk with other signaling pathways, and transgenic development have not been compiled into a single resource. Our book intends to fill this unmet need, with insight from recent advances in compatible solutes research on agriculturally important crop plants.

Due to the huge quantity and diverse nature of their metabolic pathways, fungi have great potential to be used for the production of different biofuels such as bioethanol, biobutanol, and biodiesel. This book presents recent advances, as well as challenges and promises, of fungal applications in biofuel production, subsequently discussing plant pathogenic fungi for bioethanol and biodiesel production, including their mechanisms of action. Additionally, this book reviews biofuel production using plant endophytic fungi, wood-rotting fungi, fungal biocontrol agents, and gut fungi, and it investigates highly efficient fungi for biofuel production and process design in fungal-based biofuel production systems. Finally, life cycle assessment of fungal-based biofuel production systems are discussed in this volume.
