For præcis 100 år siden rejste tre unge danske landmænd til Japan for at opbygge mønsterlandbrug på øen Hokkaido. De var udvalgte og inviterede af Japans regering, der søgte viden om dansk landbrugsdrift, andelstanke og højskolebevægelse.Emil Fenger, Morten Larsen og Peder Søndergaard var de udvalgte, der drog afsted med deres familier for at drive disse mønsterfarme og være forbilleder for udviklingen af en mejeriorienteret lokal kvægdrift. Men pionerindsatsen påvirkede de unge landmænd og deres familier, og de ofte svære og omkostningsfulde erfaringer var på både menneskeligt og økonomisk plan store.De danske pionerer skabte et stykke japansk Skandinavien, og de var medvirkende til, at den nordligt liggende japanske ø i dag er et mejericentrum i Japan.Bogen er en nybygger- og udviklingshistorie om japansk interesse for dansk og skandinavisk landbrugskultur, og om unge danske landbrugspionerer i et meget fremmed land og deres personlige livshistorier.Asger Røjle Christensen (f. 1956) er en erfaren dansk journalist, forfatter og foredragsholder. Han har fulgt udviklingen i Japan og Østasien i mere end 35 år. Han har i alt boet i Tokyo i 13 år af sit liv, hvor han har arbejdet som korrespondent, reporter og analytiker for en række danske og skandinaviske nyhedsmedier, arrangeret studieture og fungeret som rejseleder. Asger Røjle Christensen er forfatter til en række bøger, heraf flere om Japan og japansk kultur.

The breakthrough resource for fruit and vegetable growers at every scale who want to go 'beyond organic' and build higher soil quality and fertility using fewer inputs through a unique ecosystem-balancing approach "Atthowe's book takes ecological farming to the next level. It is packed with useful, field-tested, innovative techniques for farming more gently without sacrificing productivity. . . This is the future of farming. I highly recommend this book."--Ben Hartman, author of The Lean Farm The Ecological Farm is the go-to guide for ecological growing, with a unique focus on reduced tillage, minimizing farm and garden inputs, and pest control. Reflecting the wisdom that farmer, consultant, and educator Helen Atthowe and her late husband, Carl Rosato, gained during decades of farming experience, this book guides readers on how to reduce or eliminate the use of outside inputs of fertilizer or pesticides--even those that are commonly used on certified organic orchards and market gardens. In clear language and with color photographs, charts, and graphs throughout, the book emphasizes the importance of managing the details of an entire growing system over the full life of the enterprise. Based on advances in scientific research in ecological food production, farmers, homesteaders, permaculturists, and gardeners alike will learn methods to: design a farm system that maintains a growing root in the soil year-round to feed the microbial community instead of just crops. strengthen the "immune system" of a farm or garden supply crop needs using only on-farm inputs such as cover crops and living mulch maximize the presence of beneficial insects and microbes that support healthy crop development minimize ecological impact in dealing with insect pest and disease problems The Ecological Farm also features a crop-by-crop guide to growing more than 25 of the most popular and profitable vegetables and fruits, including specific management advice for dealing with pests and diseases. The Ecological Farm makes complex, sometimes messy, ecological concepts and practices understandable to all growers, and makes healthy farming--in which nature is invited to participate--possible. "[This book] will guide all of us as we learn to farm in harmony with an ecosystem and to become obedient to the whole rather than being distracted by the urge to tinker with the parts." --Wes Jackson, cofounder and president emeritus, The Land Institute

Soybean (Glycine max L. (Merr)) is one of the most important crops worldwide. Soybean seeds are vital for both protein meal and vegetable oil. Soybean was domesticated in China, and since last 4-5 decades it has become one of the most widely grown crops around the globe. The crop is grown on an anticipated 6% of the world's arable land, and since the 1970s, the area in soybean production has the highest percentage increase compared to any other major crop. It is a major crop in the United States, Brazil, China and Argentina and important in many other countries. The cultivated soybean has one wild annual relative, G. soja, and 23 wild perennial relatives. Soybean has spread to many Asian countries two to three thousand years ago, but was not known in the West until the 18th century. Among the various constraints responsible for decrease in soybean yields are the biotic and abiotic stresses which have recently increased as a result of changing climatic scenarios at global level. A lot of work has been done for cultivar development and germplasm enhancement through conventional plant breeding. This has resulted in development of numerous high yielding and climate resilient soybean varieties. Despite of this development, plant breeding is long-term by nature, resource dependent and climate dependent. Due to the advancement in genomics and phenomics, significant insights have been gained in the identification of genes for yield improvement, tolerance to biotic and abiotic stress and increased quality parameters in soybean. Molecular breeding has become routine and with the advent of next generation sequencing technologies resulting in SNP based molecular markers, soybean improvement has taken a new dimension and resulted in mapping of genes for various traits that include disease resistance, insect resistance, high oil content and improved yield.This book includes chapters from renowned potential soybean scientists to discuss the latest updates on soybean molecular and genetic perspectives to elucidate the complex mechanisms to develop biotic and abiotic stress resilience in soybean. Recent studies on the improvement of oil quality and yield in soybean have also been incorporated.

Over the last few decades, various techniques have been developed to alter the properties of plants and animals.  While the targeted transfer of recombinant DNA into crop plants remains a valuable tool to achieve a desirable breeding outcome, integration of transgenes into the host genome has been random, which in part, leads to reduced acceptance of GMOs by the general population in some parts of the world. Likewise, methods of induced mutagenesis, such as TILLING, have the disadvantage that many mutations are induced per plant, which has to be removed again by expensive backcrossing. Advances in genome sequencing have provided more and more information on differences between susceptible and resistant varieties, which can now be directly targeted and modified using CRISPR/Cas9 technology. By selecting specific gRNAs occurrence of off-target modifications are comparatively low. ZFNs and TALENs- based approaches required re-engineering a new set of assembled polypeptides for every new target site for each experiment. The difficulty in cloning and protein engineering prevented these tools from being broadly adopted by the scientific community.  Compared to these technologies, designing the CRISPR toolbox is much simpler and more flexible. CRISPR/Cas9 is versatile, less expensive and highly efficient. It has become the most widely used technology for genome editing in many organisms.Since its inception as a powerful genome-editing tool in late 2012, this breakthrough technology has completely changed how science is performed. The first few chapters in this book introduce the basic concept, design and implementation of CRISPR/Cas9 for different plant systems. They are followed by in-depth discussions on the legal and bio-safety issues accompanying commercialization and patenting of this emerging technology. Lastly, this book covers emerging areas of new tools and potential applications. We believe readers, novice and expert alike, will benefit from this all-in-one resource on genome editing for crop improvement.Chapter 17 is available open access under a Creative Commons Attribution 4.0 International License via link.springer.com.

This contributed volume explores how plant growth-promoting rhizobacterias (PGPR) provide a wide range of benefits to the plant. Further, it discusses the key roles PGPR play in nutrient acquisition and assimilation, improved soil texture, secreting, and modulating extracellular molecules. The book outlines how plant secondary metabolites are natural sources of biologically active compounds used in a wide range of applications, and surveys the significant role of volatile organic compounds (VOCs) in plant communication by mediating above- and below-ground interactions between plants and the surrounding organisms.This volume compiles research from leading scientists from across the globe, linking the translation of basic knowledge to innovative applied research. The book focuses on the following three categories: 1) understanding the secondary metabolites produced by PGPR, the signaling mechanisms and how they affect plant growth, 2) the plausible role of volatile organic compounds produced by PGPR, their role and the signaling mechanism for plant growth promotion, and  3) Applications of VOCs and secondary metabolites of PGPR for seed germination, plant growth promotion; stress tolerance and in-plant health and immunity.

Wheat (Triticum L.), an annual herbaceous plant in Poacae (Gramineae) family, settles in the Triticeae (Hordeae) subfamily. The grasses (Poaceae Barnhart) are the fifth largest (monocotyledonous flowering) plant family and of great importance for human civilization and life. Cereal crops such as maize, wheat, rice, barley, and millet are the domesticated ones in the family. It is still the most vital economical plant family in modern times, providing food, forage, building materials (bamboo, thatch), and fuel (ethanol). Wheat has many accessions in national and international gene banks. The estimated number of wheats by FAO in 2010 is 856,000, and, followed by rice (774,000), and barley (467,000). However, the recent consumer's (misdirected) focus on gluten content and nutritional value urges scientists to reexamine their knowledge about wheat (i.e., origin, evolution, and general and special quality characteristics), as well as their wild relatives and landraces for newer possible genetic resources. Cultured or non-cultured ancestral wheats: einkorn, emmer, wild emmer, spelt, macha, and vavilovii are still limitedly grown on the higher areas in Turkey, Italy, Germany, Morocco, Israel, and Balkan countries. They are exploited mostly for their desired agronomic, and specific quality. In some cultures, wheat species are believed to be therapeutic, with bioactive compounds that reduce and inhibit stubborn illnesses such as diabetes, cancer, Alzheimer, and cardiovascular diseases. In this book, we summarize the importance of ancestral wheat species, and provide a prospect for their future with special considerations in terms of species conservation and improvement. 

Crop plants growing under field conditions are constantly exposed to various abiotic and biotic stress factors leading to decreased yield and quality of produce. In order to achieve sustainable development in agriculture and to increase agricultural production for feeding an increasing global population, it is necessary to use ecologically compatible and environmentally friendly strategies to decrease the adverse effects of stresses on the plant. Selenium is one of the critical elements from the biological contexts because it is essential for human health; however, it becomes toxic at high concentrations. It has been widely reported that selenium can promote plant growth and alleviate various stresses as well as increase the quantity and quality of the yield of many plant species. Nonetheless, at high concentrations, selenium causes phytotoxicity. In the last decade, nanotechnology has emerged as a prominent tool for enhancing agricultural productivity. The production and applications of nanoparticles (NPs) have greatly increased in many industries, such as energy production, healthcare, agriculture, and environmental protection. The application of NPs has attracted interest for their potential to alleviate abiotic and biotic stresses in a more rapid, cost-effective, and more sustainable way than conventional treatment technologies. Recently, research related to selenium-NPs-mediated abiotic stresses and nutritional improvements in plants has received considerable interest by the scientific community. While significant progress was made in selenium biochemistry in relation to stress tolerance, an in-depth understanding of the molecular mechanisms associated with the selenium- and nano-selenium-mediated stress tolerance and bio-fortification in plants is still lacking. Gaining a better knowledge of the regulatory and molecular mechanisms that control selenium uptake, assimilation, and tolerance in plants is therefore vital and necessary to develop modern crop varieties that are more resilient to environmental stress. This book provides a comprehensive overview of the latest understanding of the physiological, biochemical, and molecular basis of selenium- and nano-selenium-mediated environmental stress tolerance and crop quality improvements in plants. It helps researchers to develop strategies to enhance crop productivity under stressful conditions and to better utilize natural resources to ensure future food security and to reduce environmental contamination. Finally, this book is a valuable resource for promoting future research into plant stress tolerance, and  a reference book for researchers working on developing plants tolerant to abiotic and biotic stressors as well as bio-fortification and phytoremediation.

This book explores recent advances in the microbial production of xylitol and its applications in food and medical sector. Xylitol is an important biomolecule from lignocellulose biorefinery which is produced from the xylose by chemical reactions or microbial fermentation methods. Currently, the demand of xylitol at commercial scale is being met through chemical methods. However, recent breakthroughs made in plant cell wall destruction, genetic engineering to develop the designer microorganisms, fermentation methods and media formulations and downstream processing have led the ways for sustainable production of xylitol at commercial scale in lignocellulose biorefineries. Microbial production of xylitol is preferred over the chemical processes as it is environmentally friendly, higher process efficiency with the desired product yield, and product recovery with minimum impurities. This book is a unique compilation of 11 book chapters written by experts in their respective fields. These chapters present critical insights and discuss the current progress and future progress in this area into fermentative xylitol production.Chapter 9 is licensed under the terms of the Creative Commons Attribution 4.0 International License.
