Plant Micronutrient Use Efficiency: Molecular and Genomic Perspectives in Crop Plants presents information on the complex mechanisms regulating micronutrient use efficiency in plants. Understanding this science is essential for the development of new varieties of crop plants that are more resilient to micronutrient stress, as well as plants with increased bioavailable concentrations of essential micronutrients. This book explores the discovery of novel genes and key metabolic pathways associated with micronutrient use efficiency in plants, gives an analyses of the gene expression patterns in plants in response to low and/or high nutrient levels, and investigates the potential functions of these genes and their products. Strategies to enhance micronutrient use efficiency and stress tolerance, to develop bio-fortified crop, and to improve the sustainable utilization of natural resources are critically evaluated. The book contains both fundamental and advanced information as well as critical commentaries that are useful for those involved in the various fields that make up the plant sciences.

Plant improvement has shifted its focus from yield, quality and disease resistance to factors that will enhance commerical export, such as early maturity, shelf life and better processing quality. Conventional plant breeding methods aiming at the improvement of a self-pollinating crop, such as wheat, usually take 10-12 years to develop and release of the new variety. During the past 10 years, significant advances have been made and accelerated methods have been developed for precision breeding and early release of crop varieties. This work summarizes concepts dealing with germplasm enhancement and development of improved varieties based on innovative methodologies that include doubled haploidy, marker assisted selection, marker assisted background selection, genetic mapping, genomic selection, high-throughput genotyping, high-throughput phenotyping, mutation breeding, reverse breeding, transgenic breeding, shuttle breeding, speed breeding, low cost high-throughput field phenotyping, etc. It is an important reference with special focus on accelerated development of improved crop varieties.

Environmental and specific diversity in the Chihuahuan desert in general, and in the Cuatro Cienegas Basin in particular, has long been recognized as outstanding. This book provides a global ecological overview, together with in-depth studies of specific processes. The Chihuahuan desert is the warmest in North America, and has a complex geologic, climatic and biogeographical history, which affects today's distribution of vegetation and plants and generates complex phylogeographic patterns. The high number of endemic species reflects this complex set of traits. The modern distribution of environments, including aquatic and subaquatic systems, riparian environments, gypsum dunes and gypsum-rich soils, low levels of phosphorous and organic matter, and high salinity combined with an extreme climate call for a range of adaptations. Plants are distributed in a patchy pattern based on punctual variations, and many of them respond to different resources and conditions with considerable morphological plasticity. In terms of physiological, morphological and ecological variability, cacti were identified as the most important group in specific environments like bajadas, characterized by high diversity values, while gypsophytes and gypsovagues of different phylogenies, including species with restricted distribution and endemics.

The importance of a complementary approach to animal health is highlighted in this book, with core themes encompassing reviews of traditional veterinary medicine for common diseases afflicting livestock, as well as local practices in different areas of the world. The book includes chapters on ethnoveterinary medicine used to prevent and treat ticks and tick-borne diseases, infectious diseases and parasites. Ethnoveterinary practices in parts of the world which have not been comprehensively reviewed before are highlighted, including Estonia, Belarus and the Maghreb - the north-western tip of Africa. A fascinating account of African ethnoveterinary medicine and traditional husbandry practices is provided by a veteran in the field with a wealth of practical experience in the area. Neglected areas of research involve the relationship of ethnoveterinary medicine with environmental, ethical, cultural and gender aspects, and leading experts explore these issues. The book is intended to provide an informative compilation of current research and future prospects in ethnoveterinary medicine, which hopes to inform and encourage investigations in new directions. Sustainable development requires a concerted effort to combine indigenous knowledge systems with scientific research to improve animal health. This is the case not only in rural areas where access to orthodox veterinary health care may be limited, but also against the backdrop of antibiotic resistance and increased demand for alternative and complementary therapies to enhance the health of both production and companion animals. Students, academics and veterinary professionals will find this book a useful addition to knowledge on present and future aspects of ethnoveterinary research.

This book addresses all the major mechanisms by which endophytes are thought to impact plant growth and health. A unique aspect of this publication is that it is multidisciplinary, covering plant microbiology, plant physiology, fungal and bacterial endophytes, plant biochemistry, and genomics. Just as research on the mammalian microbiome has demonstrated its importance for overall health of the host, the plant microbiota is essential for plant health in natural environments. Endophytes, the microorganisms living fully within plants, can provide a multitude of benefits to the host including N-fixation, P solubilization, increased photosynthetic efficiency and water use efficiency, stress tolerance, pathogen resistance, and overall increased growth and health. A variety of culturable endophytes have been isolated and shown to be mutualistic symbionts with a broad range of plant species. These studies point to the functional importance of the microbiota of plants and suggest the potential for tailoring plant microbiota for improved vigor and yields with reduced inputs. This review covers the major benefits of microbial endophytes to plants and discusses the implications of using symbiosis as an alternative to chemical inputs for agriculture, forestry, and bioenergy.

Celebrating Fifty Years of Picador Books In this acclaimed travel memoir Jamaica Kincaid chronicles a spectacular and exotic three-week trek through the Himalayan land of Nepal, where she and her companions are gathering seeds for planting at home. The natural world and, in particular, plants and gardening are central to Kincaid's work. Among Flowers intertwines meditations on nature and stunning descriptions of the Himalayan landscape with observations on the ironies, difficulties and dangers of this magnificent journey. For Kincaid and three botanist friends, Nepal is a paradise, a place where a single day's hike can traverse climate zones, from subtropical to alpine, encompassing flora suitable for growing at their homes, from Wales to Vermont. Yet as she makes clear, there is far more to this foreign world than rhododendrons that grow thirty feet high. Danger, too, is a constant companion - and the leeches are the least of their worries. Unpredictable Maoist guerrillas live in these perilous mountains, and when they do appear - as they do more than once - their enigmatic presence lingers long after they have melted back into the landscape. And Kincaid, who writes of the looming, lasting effects of colonialism in her works, necessarily explores the irony of her status as memsahib with Sherpas and bearers. A wonderful blend of introspective insight and beautifully rendered description, Among Flowers is a vivid, engrossing, and characteristically frank memoir from one of the most striking voices in contemporary literature. Part of the Picador Collection, a new series showcasing the best in modern literature.

This book highlights various designs for urban green spaces and their functions. It provides an interesting meeting point between Asian, European and North America specialists (researchers, planners, landscape architects) studying urban biodiversity; urban biodiversity and green space; relations between people and biodiversity. The most important feature of this book is the unique point of view from each contributor towards "the relationship between nature and people in urban areas", in the context of the ecosystem and biodiversity in urban areas and how to manage them. All chapters explore and consider the relationship between humans and nature in cities, a subject which is taking on increasing importance as new cities are conceptualized and planned. These discussion and examples would be useful for urban ecology researchers, biologists, city planners, government staff working in city planning, architects, landscape architects, and university instructors. This book can also be used as a textbook for undergraduate and postgraduate city planning, architecture or landscape architecture courses.

This book gathers the latest findings on the microbial ecology of saline habitats, plant-microbe interactions under saline conditions, and saline soil reclamation for agricultural use. The content is divided into four main parts: Part I outlines the definition of salinity, its genesis and impacts, and microbial diversity in saline habitats. Part II deals with impact of salinity on microbial and plant life/health. Part III highlights plant - microbe interactions in saline environments, and Part IV describes strategies for mitigation and reclamation of saline soils. The salinization of arable land is steadily increasing in many parts of the world. An excessive concentration of soluble salts (salinity) in soils or irrigation water adversely affects plant growth and survival. This problem is exacerbated in arid and semiarid areas due to their low precipitation and high evaporation rates. In turn, poor management practices and policies for using river water for the irrigation of agriculture crops often lead to the secondary salinization of soils. Considering the growing demands of a constantly expanding population, understanding the microbial ecology and interactions under saline conditions and their implications for sustainable agriculture is of utmost importance. Providing both an essential review of the status quo and a future outlook, this book represents a valuable asset for researchers, environmentalists and students working in microbiology and agriculture. .

This book systematically discusses the vegetation dynamics in northern China since the LGM, with a focus on three dominant tree species (Pinus, Quercus and Betula). By integrating methods of palaeoecology, phylogeography and species distribution model, it reconstructs the glacial refugia in northern China, demonstrating that the species were located further north than previously assumed during the LGM. The postglacial dynamics of forest distribution included not only long-distance north-south migration but also local spread from LGM micro-refugia in northern China. On the regional scale, the book shows the altitudinal migration pattern of the three dominant tree genera and the role of topographical factors in the migration of the forest-steppe border. On the catchment scale, it analyzes Huangqihai Lake, located in the forest-steppe ecotone in northern China, to indentify the local forest dynamics response to the Holocene climatic change. It shows that local forests have various modes of response to the climate drying, including shrubland expansion, savannification and replacement of steppe. In brief, these studies at different space-time scales illustrate the effects of climate, topography and other factors on forest migration.

This book gathers the latest insights into soil health and its sustainability, providing an up-to-date overview of the various aspects of soil quality and fertility management, e.g., plant-microbe interactions to maintain soil health; and the use of algal, fungal and bacterial fertilizers and earthworms for sustainable soil health and agricultural production. It first discusses the past, present, and future scenarios of soil health, and then explores factors influencing soil health, as well as the consequences of degradation of soil health for sustainable agriculture. Lastly it highlights solutions to improve and maintain soil health so as to achieve greater productivity and sustainability without damaging the soil system or the environment. Soil health is defined as the capacity of a soil to function within ecosystem frontiers, to sustain biological productivity, to maintain environmental quality and to promote plant, animal and human health. Soil health is established through the interactions of physical, chemical and biological properties, e.g., soil texture, soil structure, and soil organisms. Healthy soil provides adequate levels of macro- and micronutrients to plants and contains sufficient populations of soil microorganisms. As a result of the increasingly intensified agriculture over the past few decades, soils are now showing symptoms of exhaustion and stagnating or declining crop yields. Exploring these developments as well as possible solutions based on holistic and sustainable approaches, this book is a valuable resource for researchers in the area of soil and environmental science, agronomy, agriculture, as well as students in the field of botany, ecology and microbiology.

This book addresses various aspects of the current castor bean research, including genetics, biotechnology, comparative genomics, and more specific topics such as oil metabolism and the ricin toxin. It also presents the whole genome sequencing of the castor bean and its impact on the mining of gene families and future plant breeding. Castor bean (Ricinus communis), an oilseed plant, belongs to the Euphorbiaceae (spurge) family. It is a tropical and subtropical crop valued for the high quality and uniform nature of its oil, which is mostly composed of the uncommon fatty acid ricinoleate. Castor bean oil has important industrial applications for the production of lubricants, cosmetics, medicines, and specialty chemicals, and castor bean has also been proposed as a biodiesel crop that does not pose concerns regarding the "food versus fuel" debate. However, it accumulates the type 2 ribosome-inactivating protein ricin in its seeds, and health concerns posed by ricin's high toxicity have prevented broader cultivation. Recently, there has been renewed interest in castor bean due to potential biosecurity issues.
