Book excerpt: Common bean (Phaseolus vulgaris L.) and maize (Zea mays L.) are two crops central to indigenous America and of great global agricultural importance. However, the landraces of common bean are largely underrepresented in genebanks, and despite the importance of elements and tocochromanols to plant function and human health, there are still gaps in the understanding of the transport and accumulation of these nutrients in maize grain. Through the array of research tools offered by the field of population genomics and quantitative genetics, this dissertation works towards addressing such gaps. The genomic characterization of ~ 300 accessions of common bean from Native Seeds/SEARCH collected from southwestern US and northwestern Mexico established it as a unique and underrepresented resource that contained important genetic diversity. Five genes encoding MYB transcription factors proximal to the C locus were identified, which is a complex genomic region responsible for the primary control of seed coat patterns. An additional novel association for partial colored seed coats was identified on chromosome 10. Through genome-wide association studies (GWAS) with high density SNP set and the 1500-line Ames panel, I investigated the genetic basis of natural variation for the concentration of 11 elements in grain and identified a total of nine causal genes encoding metal chelator or transporter. Notably, two novel associations were reported between rte2 and irt1 with boron and nickel, respectively, and a potential biofortification target, nas5, was identified for both zinc and iron. Similar moderate predictive abilities (0.33-0.53) were obtained for the 11 grain elemental phenotypes with Bayesian Ridge Regression (BRR) and BayesB. However, BayesB, allowing SNPs to have large effects, had a better fit to the genetic architecture of nickel, molybdenum, and copper, thus outperforming BRR by 4-10%. Finally, through GWAS, transcriptome-wide association studies (TWAS) and expression quantitative trait locus (eQTL) mapping, 13 causal genes that were mostly under strong cis-regulatory control were identified to associate with tocochromanol levels in maize grain. Four genes were pinpointed to be associated with tocochromanol concentrations in maize grain, including vte5, dxs1, vte7, and samt. Overall, this dissertation demonstrates a multidisciplinary approach to characterize a unique common bean collection and the genetic control of its seed coat pattern, and provides a comprehensive assessment of the genetic basis of nutritional qualities in maize grain.

Book excerpt: Dry bean (Phaseolus vulgaris L.) is the most important legumes for human consumption worldwide and is an important source of protein, vitamins, and micronutrients in the human diet. This research aimed to i) uncover the genetic architecture of yield, Fe bioavailability and seed micronutrient concentration, ii) characterize the genetic control of canning quality traits, and ii) assess the accuracy of genomic prediction models for yield and end-use quality traits. The genetic architecture of yield and seed micronutrient concentration was assessed through a combination of meta-QTL analyses integrating published studies over the last two decades in dry bean. A Gaussian mixture model was used to determine the number of distinct QTL in the meta-QTL analyses. Consistent meta-QTL over different genetic backgrounds and environments were identified, reducing the confidence interval compared with initial QTL. Furthermore, a genome-wide association (GWA) study with 295 lines of the yellow bean collection and 82 yellow recombinant inbred lines identified a major QTL for Fe bioavailability related to the ground factor P gene. A black breeding panel with 415 lines was evaluated for yield and canning quality traits in two growing seasons. Consistent associations for color retention, appearance and texture of canned beans were identified across years. Genomic prediction models provided moderate to high accuracy for end-use quality traits on the yellow and black populations. The genomic prediction accuracy was related to the heritability of each trait, and improvement of accuracy was observed for complex traits when secondary traits were included in the model, while for traits with major QTL, the use of associated markers as fixed effects increased prediction ability. The use of meta-QTL analyses and GWA in this study lays a foundation of the genetic control of yield and end-use quality traits and reveals the potential of genomic prediction for these traits in dry beans.

Available in PDF, EPUB and Kindle. Book excerpt: Natural diversity has been extensively used to understand plant biology and improve crops. However, studies were commonly based on visual phenotypes or on a few measurable parameters. Nowadays, a large number of parameters can be measured thanks to next generation sequencing, metabolomics, proteomics, and transcriptomics thus providing an unprecedented resolution in the detection of natural diversity. This enhanced resolution offers new possibilities in terms of understanding plant biology. Technology advances also contribute to a better assessment of the biodiversity loss currently taking place. Hence, the topic presents an overview on efforts for maintaining biological diversity in crops, on possibilities offered by recent technologies in the assessment of natural variation, and ends with examples of the diversity found even at the cellular level.

This book was released on 2008-04-15 with total page 392 pages. Available in PDF, EPUB and Kindle. Book excerpt: The formation, dispersal and germination of seeds are crucial stages in the life cycles of gymnosperm and angiosperm plants. The unique properties of seeds, particularly their tolerance to desiccation, their mobility, and their ability to schedule their germination to coincide with times when environmental conditions are favorable to their survival as seedlings, have no doubt contributed significantly to the success of seed-bearing plants. Humans are also dependent upon seeds, which constitute the majority of the world’s staple foods (e.g., cereals and legumes). Seeds are an excellent system for studying fundamental developmental processes in plant biology, as they develop from a single fertilized zygote into an embryo and endosperm, in association with the surrounding maternal tissues. As genetic and molecular approaches have become increasingly powerful tools for biological research, seeds have become an attractive system in which to study a wide array of metabolic processes and regulatory systems. Seed Development, Dormancy and Germination provides a comprehensive overview of seed biology from the point of view of the developmental and regulatory processes that are involved in the transition from a developing seed through dormancy and into germination and seedling growth. It examines the complexity of the environmental, physiological, molecular and genetic interactions that occur through the life cycle of seeds, along with the concepts and approaches used to analyze seed dormancy and germination behavior. It also identifies the current challenges and remaining questions for future research. The book is directed at plant developmental biologists, geneticists, plant breeders, seed biologists and graduate students.

This book was released on 2017-01-28 with total page 607 pages. Available in PDF, EPUB and Kindle. Book excerpt: Genetically engineered (GE) crops were first introduced commercially in the 1990s. After two decades of production, some groups and individuals remain critical of the technology based on their concerns about possible adverse effects on human health, the environment, and ethical considerations. At the same time, others are concerned that the technology is not reaching its potential to improve human health and the environment because of stringent regulations and reduced public funding to develop products offering more benefits to society. While the debate about these and other questions related to the genetic engineering techniques of the first 20 years goes on, emerging genetic-engineering technologies are adding new complexities to the conversation. Genetically Engineered Crops builds on previous related Academies reports published between 1987 and 2010 by undertaking a retrospective examination of the purported positive and adverse effects of GE crops and to anticipate what emerging genetic-engineering technologies hold for the future. This report indicates where there are uncertainties about the economic, agronomic, health, safety, or other impacts of GE crops and food, and makes recommendations to fill gaps in safety assessments, increase regulatory clarity, and improve innovations in and access to GE technology.

Available in PDF, EPUB and Kindle. Book excerpt: 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 excerpt: In this chapter, we lead the reader through several topics related to common bean germplasm, including crop dissemination across the Old World, landraces developed by farmers, characterization and safeguard of germplasm. These topics are attracting a great deal of attention, especially in recent years, when the international community has become increasingly aware of the relevance of safeguarding plant genetic resources. Early studies were mainly aimed at performing exploratory analyses of agro-morphological traits, with the goal of improving yield and pest resistance. Moreover, phaseolin variation was studied to check the distribution of the two common bean gene pools. The recent development of DNA-based markers has allowed significant improvement in knowledge on genetic variation within the European germplasm, as well as the capacity to trace its divergence from the American germplasm. The different strategies applied to safeguard the European germplasm are described together with their drawbacks.

Available in PDF, EPUB and Kindle. Book excerpt: The common beans and pulses are diverse food resources of high nutritional value (protein, energy, fiber and vitamins and minerals) with broad social acceptance. These legume crops demonstrate global adaptability, genotypic and phenotypic diversity, and multiple means of preparation and dietary use. Beans and pulses are produced in regions as diverse as Latin America, Africa, Asia, and North America, and on a scale similar to some other crops, such as wheat, corn, rice and soybeans. Numerous factors influence utilization, including bean type and cultivar selection, cropping environment and systems, storage conditions and handling infrastructure, processing and final product preparation. Nutrient content and bio-availability are dramatically influenced by these conditions. In recent years, beans and pulses have been cited for imparting specific positive health potentiating responses, such as hypocholesteremic response, mitigation of diabetes and colonic cancer, and weight control. Enhanced dry bean utilization focused on improved dietary health is an opportunity within both subsistent and developed populations. This book provides a contemporary source of information that brings together current knowledge and practices in the value chain of beans/pulses production, processing, and nutrition. It provides in-depth coverage of a wide variety of pertinent topics including: breeding, postharvest technologies, composition, processing technologies, food safety, quality, nutrition, and significance in human health. An experienced team of over 25 contributors from North America, Asia, and Africa has written 15 chapters, divided into three sections: Overview, production and postharvest technologies of beans and pulses Composition, value-added processing and quality Culinology, nutrition, and significance in human health Contributors come from a field of diverse disciplines, including crop sciences, food science and technology, food biochemistry, food engineering, nutritional sciences, and culinology.

Available in PDF, EPUB and Kindle. Book excerpt: Grain legumes play significant and diverse role in the farming systems and provide nutrition security to the largely vegetarian and relatively poorer people around the world. These are ideal crops for achieving three simultaneous developmental goals viz. reducing poverty, improving human health and nutrition and enhancing ecosystem resilience. Globally, grain legumes are the second most important crop group next only to cereals but a large proportion of area of it is under rainfed-low input systems as compared to cereals contributing to lower yields. The other important factor responsible for reduced yield in grain legumes is the narrow genetic base of the present day pulse varieties. In order to break the yield barriers of these cultivars, new sources of genes/ alleles need to be identified and suitably incorporated into the adapted background. The information on various aspects of grain legume improvement although has been considerable in the recent past, these information are highly scattered and not available at one place. The present book consists of comprehensive and latest crop-wise information on important grain legumes of the world including their distribution, gene pool, systematics, status of genetic and genomic resources, production constraints, traits of importance, crop improvement methodologies - both conventional as well as contemporary and future strategies to be adopted for comprehensive grain legume improvement in various agro-ecological target areas of the globe. The chapters have been contributed by eminent crop experts from across the world engaged in research in their respective crops for the past several years thus providing a rare insight into the crop specific constraints and prospects drawing from their rich overall experience. The book therefore will be a useful source of information to the grain legume researchers, students, policy planners and developmental experts alike.

Available in PDF, EPUB and Kindle. Book excerpt: Grain legumes, including common-bean, chickpea, pigeonpea, pea, cowpea, lentil and others, form important constituents of global diets, both vegetarian and non-vegetarian. Despite this significant role, global production has increased only marginally in the past 50 years. The slow production growth, along with a rising human population and improved buying capacity has substantially reduced the per capita availability of food legumes. Changes in environmental climate have also had significant impact on production, creating a need to identify stable donors among genetic resources for environmentally robust genes and designing crops resilient to climate change. Genetic and Genomic Resources of Grain Legume Improvement is the first book to bring together the latest resources in plant genetics and genomics to facilitate the identification of specific germplasm, trait mapping and allele mining to more effectively develop biotic and abiotic-stress-resistant grains. This book will be an invaluable resource for researchers, crop biologists and students working with crop development. Explores origin, distribution and diversity of grain legumes Presents information on germplasm collection, evaluation and maintenance Offers insight into pre-breeding/germplasm enhancement efforts Integrates genomic and genetic resources in crop improvement Internationally contributed work
