Book Description
Drought causes significant yield reductions in soybean. The development of drought-tolerant cultivars is an effective alternative to overcome this abiotic stress. Slow wilting, prolonged nitrogen fixation, and minimal yield reduction under water stress play an important role in evaluating breeding materials. Despite advances in knowledge about plant responses to drought conditions, there is little information on effective methodologies for phenotype screening in the field, and some QTLs have been identified for drought tolerance. Field screenings under drought and irrigated conditions are necessary to detect drought tolerant lines. In addition, QTLs and molecular makers associated with drought tolerance traits will greatly facilitate the development of tolerant lines through marker-assisted selection (MAS). The objectives of this study were: 1) to evaluate whether selection of high-yielding lines under irrigation in the preliminary stage is a positive predictor of the performance of these lines under drought conditions, and 2) to identify/confirm QTLs associated with slow wilting and nitrogen fixation for drought tolerance. For the first objective, yield performances of 87 genotypes derived from three different populations were evaluated under rain-fed conditions versus standard irrigation. The second objective was to identify QTLs associated with slow wilting, shoot ureides and nitrogen concentrations in soybeans. For this objective, 148 lines from an F4-derived population (R07-7044 x R01-581) were screened with SNP markers and molecular analysis was conducted. Results for the first project showed four different types of yield performance on the lines. The high-yielding lines under full irrigation also had high yields under drought indicating that the selection of high-yielding lines in initial stages under irrigation is a good indicator of the profitable yielding lines under moderate drought conditions. In the second project, results showed two new QTLs for shoot nitrogen on chromosomes 6 and 11, and confirmed two shoot ureide QTLs on chromosomes 10 and 13. Four new QTLs for wilting were identified on chromosomes 11, 13, 14, and 18. These newly confirmed QTLs and molecular markers will be useful for marker-assisted selection for drought tolerance improvement in a soybean breeding program.

Book Description
Climate change is a serious problem influencing agricultural production worldwide and challenging researchers to investigate plant responses and to breed crops for the changed growing conditions. Abiotic stresses are the most important for crop production, affecting about 96.5% of arable land worldwide. These stress factors include high and low temperature, water deficit (drought) and flooding, salinity, heavy metals, UV radiation, light, chemical pollutants, and so on. Since some of the stresses occurred simultaneously, such as heat and water deficit, causing the interactions of physiological processes, novel multidisciplinary solutions are needed. This book provides an overview of the present state in the research of abiotic stresses and molecular, biochemical, and whole plant responses, helping to prevent the negative impact of global climate change.

Book Description
Soybean is the most important oilseed and livestock feed crop in the world. These dual uses are attributed to the crop's high protein content (nearly 40% of seed weight) and oil content (approximately 20%); characteristics that are not rivaled by any other agronomic crop. Across the 10-year period from 2001 to 2010, world soybean production increased from 168 to 258 million metric tons (54% increase). Against the backdrop of soybean's striking ascendancy is increased research interest in the crop throughout the world. Information in this book presents a comprehensive view of research efforts in genetics, plant physiology, agronomy, agricultural economics, and nitrogen relationships that will benefit soybean stakeholders and scientists throughout the world. We hope you enjoy the book.

Book Description
Crop Physiology: Case Histories of Major Crops updates the physiology of broad-acre crops with a focus on the genetic, environmental and management drivers of development, capture and efficiency in the use of radiation, water and nutrients, the formation of yield and aspects of quality. These physiological process are presented in a double context of challenges and solutions. The challenges to increase plant-based food, fodder, fiber and energy against the backdrop of population increase, climate change, dietary choices and declining public funding for research and development in agriculture are unprecedented and urgent. The proximal technological solutions to these challenges are genetic improvement and agronomy. Hence, the premise of the book is that crop physiology is most valuable when it engages meaningfully with breeding and agronomy. With contributions from 92 leading scientists from around the world, each chapter deals with a crop: maize, rice, wheat, barley, sorghum and oat; quinoa; soybean, field pea, chickpea, peanut, common bean, lentil, lupin and faba bean; sunflower and canola; potato, cassava, sugar beet and sugarcane; and cotton. A crop-based approach to crop physiology in a G x E x M context Captures the perspectives of global experts on 22 crops

Book Description
Learn how to best improve yield in cereal plants—even in dry conditions The impact of drought on crop production can be economically devastating. Drought Adaptation in Cereals provides a comprehensive review of the latest research on the tolerance of cereal crops to water-limited conditions. Renowned experts extensively describe basic concepts and cutting-edge research results to clearly reveal all facets of drought adaptation in cereals. More than simply a fine reference for plant biology and plant improvement under water-limited conditions, this book spotlights the most relevant biological approaches from plant phenotyping to functional genomics. The need to understand plant response to the lack of water is integral to forming strategies to best manage crops. Drought Adaptation in Cereals starts by offering an overview of the biological basis and defines the adaptive mechanisms found in plants under water-limited conditions. Different approaches are presented to provide understanding of plant genetics basics and plant breeding, including phenotyping, physiology, and biotechnology. The book details drought adaptation mechanisms at the cellular, organ, and entire plant levels, focusing on plant metabolism and gene functions. This resource is extensively referenced and contains tables, charts, and figures to clearly present data and enhance understanding. After a foreword by J. O'Toole and a prologue by A. Blum, Drought Adaptation in Cereals presents a full spectrum of informative topics from other internationally respected scientists. These include: drought’s economic impact (P. Heisey) genotype-by-environment interactions (M. Cooper) secondary traits for drought adaptation (P. Monneveux) leaf growth (F. Tardieu) carbon isotope discrimination (T. Condon) drought adaptation in barley (M. Sorrells), maize (M. Sawkins), rice (R. Lafitte), sorghum (A. Borrell) and wheat (M. Reynolds) carbohydrate metabolism (A. Tiessen) the role of abscisic acid (T. Setter) protection mechanisms and stress proteins (L. Mtwisha) genetic basis of ion homeostasis and water deficit (H. Bohnert) transcriptional factors (K. Yamaguchi-Shinozaki) resurrection plants (D. Bartels) Drought Adaptation in Cereals is a unique, vital reference for scientists, educators, and students in plant biology, agronomy, and natural resources management.
