This book will expound the latest information on the current state of persimmon genomics and transcriptomics, with a particular focus on the latest findings and analysis in relation to the most important agronomic traits. The genus Diospyros contains about 400 species distributed all continents of the globe. Most of Diospyros species are distributed in the tropical and subtropical regions, while cultivated persimmon or simply kaki (Diospyros kaki) originates in East Asia and has been grown in China, Japan and Korea for many years. World production of persimmon has been increasing continuously since 1990s, with China being the most producer. Outside Asia, kaki production has been rapidly increasing in Spain in recent years. Because kaki is mostly hexaploid (2n = 6x =90) and its genome size is quite large with the flow cytometric analysis estimation of about 900 Mb, genetic and molecular studies in persimmon are quite complicated. Diploid close relatives of kaki, D. lotus and D. oleifera have been recently used as model species of kaki. Utilizing these species, molecular basis of several economically molecular basis of important traits such as sexuality and astringency has been studied, giving important information for kaki breeding.

This handbook offers effective strategies to modify and adjust crop production processes to decrease the toxicity of soil contaminants, balance soil pH, improve root growth and nutrient uptake, and increase agricultural yield. The Handbook of Soil Acidity provides methods to, measure soil acidity, determine the major causes of soil acidification, calculate acidification rates for specific crop sequences, identify high-risk areas for soil acidification, and model acidification phenomena. This is an essential resource for plant, crop, soil, and environmental scientists, plant and crop physiologists, botanists, agronomists, agriculturists, and upper-level undergraduate, graduate, and continuing-education students in these disciplines.
Nitrogen is an essential element for plant growth. During the green revolution nitrogenfertilisation was responsible for spectacular yield increases. At present yield is balanced with commitments towards the environment and sustainable agriculture. For agro-biotechnology comprehensive knowledge of plant functioning is needed. Yield improvement and accumulation of essential nitrogen compounds is relying on selection and gene technologies. Research on the uptake, acquisition and assimilation of nitrogen, as well as the synthesis and storage of reserve and defence N-compounds, therefore, is essential. The third volume in the Plant Ecophysiology series integrates functional and molecular physiology with ecophysiological and sustainable agricultural approaches to get a better understanding of the regulation and the impact of environmental and stress signals on nitrogen acquisition and assimilation. The book is of interest for advanced students and junior researchers and supplies comprehensive information for scientists working in the field of nitrogen metabolism and readers interested in sustainable development.
This volume provides an overview of methods for plant species, mainly species with high economic value, to achieve in vitro propagation through somatic embryogenesis.

The refinement of molecular techniques and the development of new probes of the phylogeny of diazotrophs has revealed an extreme biodiversity among the nitrogen fixers, which helps explain the role that nitrogen fixation plays in maintaining life on Earth. The most efficient ecosystems are those where the bacteria are associated with a plant in differentiated organs to benefit crop productivity. Most short-term benefit from fundamental research on nitrogen fixation is likely to result in the improvement of existing nitrogen-fixing symbiotic or associative systems. Longer-term efforts are aimed at extending the nitrogen-fixing capacity to other organisms, including transfer of the genetic information for efficient nitrogen fixation into the plant genome and using current knowledge of microbe-plant interactions to extend symbiosis to cereals and, in particular, to rice. Related challenges in sustainable agriculture and forestry include the creation of new nitrogen-fixing associations. All of these approaches were discussed at the 11th International Congress on Nitrogen Fixation, Paris, France, July 20-25, 1997 and covered in the present proceedings volume.
This book is about the invisible or subtle nature of food and farming, and also about the nature of existence. Everything that we know (and do not know) about the physical world has a subtle counterpart which has been scarcely considered in modernist farming practice and research. If you think this book isn't for you, if it appears more important to attend to the pressing physical challenges the world is facing before having the luxury of turning to such subtleties, then think again. For it could be precisely this worldview - the one prioritises the physical-material dimension of reality - that helped get us into this situation in the first place. Perhaps we need a different worldview to get us out? This book makes a foundational contribution to the discipline of Subtle Agroecologies, a nexus of indigenous epistemologies, multidisciplinary advances in wave-based and ethereal studies, and the science of sustainable agriculture. Not a farming system in itself, Subtle Agroecologies superimposes a non-material dimension upon existing, materially-based agroecological farming systems. Bringing together 43 authors from 12 countries and five continents, from the natural and social sciences as well as the arts and humanities, this multi-contributed book introduces the discipline, explaining its relevance and potential contribution to the field of Agroecology. Research into Subtle Agroecologies may be described as the systematic study of the nature of the invisible world as it relates to the practice of agriculture, and to do this through adapting and innovating with research methods, in particular with those of a more embodied nature, with the overall purpose of bringing and maintaining balance and harmony. Such research is an open-minded inquiry, its grounding being the lived experiences of humans working on, and with, the land over several thousand years to the present. By reclaiming and reinterpreting the perennial relationship between humans and nature, the implications would revolutionise agriculture, heralding a new wave of more sustainable farming techniques, changing our whole relationship with nature to one of real collaboration rather than control, and ultimately transforming ourselves.
This second edition describes up-to-date methodological approaches, ranging from physiological assays to imaging and molecular techniques, to study a wide variety of plant responses to environmental cues. Chapters are divided into four sections detailing protocols to investigate key biological processes underlying plant environmental responses in the model organisms Arabidopsis thaliana and Physcomitrella patens as well as in different crop species. Written in the format of the highly successful Methods in Molecular Biology series, each chapter includes an introduction to the topic, lists necessary materials and reagents, includes tips on troubleshooting and known pitfalls, and step-by-step, readily reproducible protocols. Authoritative and cutting-edge, Environmental Responses in Plants, Second Edition aims to be a foundation for future studies and to be a source of inspiration for new investigations in the field.

Fresh? Juice? Paste? Canned? Stewed? Diced? Pureed? Sun Dried? Salsa? Sauce? Ketchup? Rare is the cuisine that does not make use of the tomato in some way, shape, or form, and the resulting culinary popularity of the tomato has led to its proliferation in fields and farms around the world. While some may still argue whether the tomato is a fruit or a vegetable, few would argue that tomato crops are highly lucrative, attractive to farmers in both developing and developed countries and on large and small farms alike. In fact, for those crops with significant global volume and market share, tomatoes are the highest valued among those crops that lack an affiliation to mind-altering drugs. But, the tomato can be a persnickety critter. The tomato doesn't like it too hot, too chilly, too wet, too dry, or too fertile. Many don't ripen at the same time. Most are easily bruised. And, the selective breeding that has yielded a larger, more attractive, and deep red tomato has also mercilessly drained much of the taste and flavor from a once sweet and delectable fruit. Enter the world of sensors and modern sensing technology. The Internet of Things (IOT), when using well chosen, well networked, and well aggregated sensors, has shown tremendous potential to support precision agriculture, providing a more detailed picture of crops than was previously possible using conventional crop monitoring techniques. But, the stringent resources and tight profit margins that are a fact of life among many tomato growing operations, large and small, mean that sensor technologies must be chosen and used carefully. There is no doubt that each sensor must earn its keep in producing the perfect tomato. With that in mind, this book explores key opportunities to marry the potential of sensors that are networked within the IOT to the needs of tomato production in ways that are economically fruitful, technologically robust, and sustainable overall.
The first premise of this book is that farmers need access to options for improving their situation. In agricultural terms, these options might be manage ment alternatives or different crops to grow, that can stabilize or increase household income, that reduce soil degradation and dependence on off-farm inputs, or that exploit local market opportunities. Farmers need a facilitating environment, in which affordable credit is available if needed, in which policies are conducive to judicious management of natural resources, and in which costs and prices of production are stable. Another key ingredient of this facilitating environment is information: an understanding of which options are viable, how these operate at the farm level, and what their impact may be on the things that farmers perceive as being important. The second premise is that systems analysis and simulation have an impor tant role to play in fostering this understanding of options, traditional field experimentation being time-consuming and costly. This book summarizes the activities of the International Benchmark Sites Network for Agrotechnology Transfer (IBSNAT) project, an international initiative funded by the United States Agency for International Development (USAID). IBSNAT was an attempt to demonstrate the effectiveness of understanding options through systems analysis and simulation for the ultimate benefit of farm households in the tropics and subtropics. The idea for the book was first suggested at one of the last IBSNAT group meetings held at the University of Hawaii in 1993."
This edited book provides the first comprehensive overview on conventional and emerging processing technologies for the extraction and purification of proteins and/or peptides from plant sources with a special focus on subsequent product development. The book opens with an introduction to the most conventional processing technologies used in industry today: the alkaline extraction followed by isoelectric precipitation, and air classification. The book also focusses on novel extraction and purification technologies, covering the most recent green emerging technologies based on enzymatic processes, solvents, high-pressure processing, barometric membrane technologies, and microwave-assisted extraction, among others. The final chapters bridge the gap between the presented methods and product development and highlight how these technologies can alter protein functionality and nutritional quality of the extracted protein, and thereby, impact human health. In the context of rising consumer interest in foods from plant-protein ingredients and the United Nations targets for Sustainable Development Goal 12 on 'Responsible Consumption and Production', this book will provide an indispensable resource for students, engineers and researchers in academia and industry, working in the area of food science, food technology and plant-based product development.

This volume examines the Middle East's leading armed forces and
their role in both military and political affairs. It considers
their missions, doctrine, training, equipment and effectiveness as
fighting forces. At the same time, the various expert contributors
discuss the relations between the armed forces and their respective
governments, with the issues raised ranging from internal
repression to budgetary matters. On some issues, high-ranking
officers force Arab regimes to meet their demands. In other ways,
regimes impose restrictions on the armies in order to maintian
their own political control. These mechanisms also reduce the
soldiers' military quality, and hence their ability to wage
war.
Biodesign in the Age of Artificial Intelligence: Deep Green investigates the potential of nature based technology for shaping the evolution of contemporary architecture and design. It takes on the now pervasive topic of design intelligence, extending its definition to encompass both biological and digital realms. As in their first title, Systemic Architecture: Operating Manual for the Self Organizing City, the authors engage the topic through the specific lens of their innovative design practice, ecoLogicStudio and their research at the University of Innsbruck and at the Bartlett, UCL. Part One of the book, entitled PhotoSynthetica (TM), illustrates design solutions that engage the urban microbiome and seek to achieve an immediate impact, while Part Two, entitled Deep Green, includes synthetic landscapes and operates within a much larger spatio-temporal frame, going beyond human perception and life span to envision design as a geographical and geological force. In the age of catastrophic climate change, such perceptual expansion helps to clarify that change cannot simply be stopped or rolled back. We must instead establish more positive dynamics of change within the living world. To this end, this book proposes to engage with design and architecture as an extended cognitive interface, a sentient being that is co-evolutionary and symbiotic with the living planet, contributing to its beauty and to our continued enjoyment of it. |
