        Linear Models for the Prediction of the Genetic Merit of Animals

        by Raphael A Mrode, Ivan Pocrnic

        The prediction of producing desirable traits in offspring such as increased growth rate, or superior meat, milk and wool production, is a vital economic tool to the animal scientist. Covering the fundamental principles of the application of linear models for the prediction of genetic merit in livestock, this new edition is fully updated to incorporate recent advances in methods of genomic prediction for pure and cross-bred animals. It provides models for the analysis of main production traits as well as functional traits, and includes numerous worked examples. The book covers: - models of survival analysis, social interaction and sire and dam models; - advancements in the use of SNPs in the computation of genomic breeding values; - single step approaches to genomics; - genomic non-additive models; - temporal and genomic analysis of genetic change. Suitable for postgraduate students, researchers and lecturers of animal breeding, genetics and genomics, this established textbook provides a thorough grounding in both the basics and new developments of linear models and animal genetics.

        The Quest to Conserve Rare Breeds

        Setting the Record Straight

        by Lawrence Alderson

        Since the middle of the twentieth century the world has witnessed a succession of political and social disruptions. Globalisation, technological advancement, climate change, human migration, war and conflict - all have caused major worldwide upheavals. In this light, it's unsurprising that conservation of rare breed animals has been neglected. Yet the preservation of these genetic resources - this biological diversity - is an essential ingredient of sustainable life on Earth, and not something we can afford to lose. This book, straight from the 'horse's mouth' Lawrence Alderson CBE, challenges often repeated 'facts' about livestock farming and argues for a reasoned and evidence-based approach from political and public circles. Correcting misconceptions as he goes, he recounts the creation and development of the rare breed conservation movement, addresses extinctions and genetic safe-guarding measures, and considers where we go from here. Challenged as we are by climate change, sustainability and feeding the world, perhaps it is these endangered animals that hold the answer - perhaps with them, we can adapt to our changing environment and see a way forward to a more certain future.

        Plant Biotechnology, Second Edition

        by William G. Hopkins; Series Editor: William G. Hopkins

        Over the past 25 years, terms like genetic modification, genetic engineering, recombinant DNA technology, and biotechnology have become commonplace in the news and in the public vocabulary. But biotechnology has in fact been practiced for thousands of years, with the aim of harnessing organisms for processing food and making useful products. Since the 1980s, however, recombinant DNA technology has given us the ability to modify organisms in the most fundamental way. The modification of plants by these new techniques has unleashed a storm of public controversy worldwide. Plant Biotechnology, Second Edition brings perspective to the discussion. Tracing the history of biotechnology, from its origins in antiquity through its foundations as a science in the work of Louis Pasteur to the birth of modern genetic engineering, this eBook describes traditional uses for plants, reveals how they are genetically engineered, and explains how new technology compares with conventional ways of generating new food plants. Readers will find that this accessible introduction dispels some of the myths surrounding genetic engineering, clearly presents the current impact and future potential of genetically modified plants, and provides a balanced look at the risks and benefits of biotechnology.

        Plant Genetics, Second Edition

        by Carl-Erik Tornqvist; Series Editor: William G. Hopkins

        After only 200 years, the field of genetics is young compared to how long plants and animals have inhabited the earth. What was once the scientific study of inherited traits has come to include the study of everything related to genes, the "building blocks of life," including their functions, structures, interactions, and sequences. Plant Genetics, Second Edition gives a detailed look at the genetics of plants through historical scientific achievements, discussions of genetic diversity, agricultural practices, and comparisons to animal and human genetics. A brief history provides a sketch of two genetic pioneers, Gregor Mendel and Barbara McClintock, who have left everlasting impressions on the field of plant genetics. A technical overview explains basic genetic terminology and fundamental processes. Details of some widely used methods in biotechnology are also included in an attempt to demystify certain aspects of genetic engineering. This reference is a vital tool for students and teachers.

        Research on the Inheritance of Shangshu

        by Qian Zongwu

        The manuscript is composed of 20 papers. It mainly discusses the time when the book of Confucian Classics was written and the variation of the text in the process of inheritance. It was first proposed in the history of the Book of Confucius that the book was written in the late Eastern Han Dynasty or the early Western Jin Dynasty. Wang Suzhu of "Classic Interpretations" and "Yaodian" proposed that Wang Zhu had been artificially modified by the Tang and Song people, which eventually led to Wang Su's ancient script "Shangshu" being completely unrecognizable; the demonstration of Chinese culture from Han and Tang to Ming and Qing has been maintained Strong positive output situation, wide radiation area, great influence; emphasized the current value and modern significance of studying the literature of the Book of Learning, advocated the national strategy of serving the spread of Chinese culture outside the domain, and must use the literature of the Book of Learning outside the domain Ancient Chinese literature established the right to speak Chinese culture and found the correct way and effective method for the spread of Chinese culture outside the region. The manuscript also analyzes the types of foreign texts in Dunhuang's Shangshu and its characteristics.

        Transgenic Insects

        Techniques and Applications

        by Mark Quentin Benedict, Maxwell Scott

        Technology for modifying the genotypes and phenotypes of insects and other arthropods has steadily progressed by development of more precise and powerful methods, most prominently transgenic modification. There is now almost unlimited ability to modify phenotypes to benefit human health and agriculture. Precise DNA modifications and gene drive particularly have the power to make wild-type populations less harmful in ways that could never be performed with previous transgenic approaches. This transition from primarily laboratory science to greater prominence for field applications has also necessitated a greater development of modelling, ethical considerations and regulatory oversight. The 2nd edition of Transgenic Insects contains chapters contributed by experts in the field that cover the technology and applications that are now possible. These include an increased emphasis on acceptance issues that will be necessary for application of many technologies.

        Conserving Plant Genetic Diversity in Protected Areas

        by Edited by José M Iriondo, Nigel Maxted, Mohammad E Dulloo

        Conservation in protected areas has focused on preserving biodiversity of ecosystems and species, whereas conserving the genetic diversity contained within species has historically often been ignored. However, maintaining genetic diversity is fundamental to food security and the provision of raw materials and it is best preserved within plants' natural habitats. This is particularly true for wild plants that are directly related to crop species and can play a key role in providing beneficial traits, such as pest or disease resistance and yield improvement. These wild relatives are presently threatened due to processes of habitat destruction and change and methodologies have been adapted to provide in-situ conservation through the establishment of genetic reserves within the existing network of protected areas.Providing a long-awaited synthesis of these new methodologies, this book presents a practical set of management guidelines that can be used for the conservation of plant genetic diversity of crop wild relatives in protected areas.

        Quantitative Genetics, Genomics and Plant Breeding

        by Manjit S Kang

        Since the first edition of this book was published in 2002, the field of quantitative genetics, genomics and breeding has changed markedly. To meet this challenge, this new edition has only five updated chapters; the remaining 17 chapters are entirely new. This book presents state-of-the-art, authoritative chapters on 1) Genomics, Quantitative Trait Loci and Molecular Breeding (11 chapters) and 2) Multi-environment Trials and Plant Breeding (11 chapters). These chapters emphasise the application of genomics and genome editing techniques in the context of plant breeding, and the latest in examining genotype X environment interactions in the field through applying quantitative genetics techniques. There is a particular focus on using genomic information to help evaluate traits that can combat abiotic stresses, genome-wide association mapping, high-throughput phenotyping, bioinformatics and the use of big data and gene editing techniques. Chapters describe breeding approaches that help make use of alien germplasm and enable biofortification, and the intergration of statistical techniques. Examples are taken from across crop science and a very wide geographical base.

        Genetic Epidemiology

        Methods and Applications

        by Melissa A Austin, Terri H Beaty, W David Dotson, Kelly Edwards, Stephanie M Fullerton, Marta Gwinn, Muin J Khoury, Barbara McKnight, Deborah Nickerson, Ruth Ottman, Bruce M Psaty, Stephen M Schwartz, John A Stamatoyannopolous, Janet L Stanford, Timothy A Thornton

        Genetic epidemiology plays a key role in discovering genetic factors influencing health and disease, and in understanding how genes and environmental risk factors interact. There is growing interest in this field within public health, with the goal of translating the results into promoting health and preventing disease in both families and populations. This textbook provides graduate students with a working knowledge of genetic epidemiology research methods. Following an overview of the field, the book reviews key genetic concepts, provides an update on relevant genomic technology, including genome-wide chips and DNA sequencing, and describes methods for assessing the magnitude of genetic influences on diseases and risk factors. The book focuses on research study designs for discovering disease susceptibility genes, including family-based linkage analysis, candidate gene and genome-side association studies, assessing gene-environment interactions and epistasis, studies of Non-Mendelian inheritance, and statistical analyses of data from these studies. Specific applications of each research method are illustrated using a variety of diseases and risk factors relevant to public health, and useful web-based genetic analysis software, human reference panels, and repositories, that can greatly facilitate this work, are described. Concluding with a review of ethical issues and a framework for translating human genomics research to clinical practice and public health benefit, this textbook is an essential new resource for graduate students in epidemiology and public health genetics.

        Small Animal Veterinary Psychiatry

        by Sagi Denenberg, Ali Thompson

        Problem behaviours are often the result of how an animal thinks and feels, genetics, and environmental influences. Steering away from just description diagnoses and focusing instead on emotional and cognitive causes, this book provides a practical approach to diagnosing, treating, and managing behaviour pathologies in dogs and cats. Beginning by addressing cases in the first opinion practice, this book then considers physical disorders that may lead to or exacerbate abnormal behavior. From there, the focus shifts to mental and emotional health, from an assessment of normal behavior and giving juveniles an optimal start in life, to diagnosing mental and emotional disorders, addressing emotions such as anxiety and frustration, and how to manage these issues - by modifying behavior, managing the animal's environment, training, and, when necessary, the use of medications. The second half of the book then addresses owner concerns, including management problems, aggression, affective disorder, elimination disorder, abnormal and repetitive behaviours and ageing-related problems. With an emphasis on helping first line veterinarians identify common presentations and offer help to owners, this book: - Addresses both normal and abnormal behaviour in cats and dogs from an emotion and cognition perspective; - Provides behaviour modification protocols, and drug doses and indications; - Includes handouts to be used both within the practice and with clients to help the veterinary surgeon manage the case. Written by international experts, the book translates their insights and experience into approaches taken in behavioural medicine. Also including the most up-to-date drugs, it is an important resource for both small animal veterinarians and students of veterinary medicine or animal behaviour.

        Genetic Diversity of Cacao and its Utilization

        by Basil G D Bartley

        The cacao (Theobroma cacao) plant is an important Neo-Tropical species whose natural habitat is the Amazon basin. Over the last 30 years there has been a considerable geographical expansion in the availability of cacao genetic resources. As a result the plant has a rich genetic diversity that exists at two levels: that of the primitive populations in the area of original distribution of the species, and that of the derived cultivated populations. This book provides a comprehensive review of our current knowledge of the diversity of the species. It starts by examining the diversity and inheritance of the characteristics of primitive populations in the Amazonian and Caribbean regions. It then looks at the evolution of diversity within cultivated populations first in South America and around the Caribbean, and then beyond the Americas. The book describes the inter-relationships between populations based on morphological and molecular markers. It also examines the conservation of genetic resources and how these genetic resources can be utilized to produce new cultivars.

        Genetically Modified Organisms

        A Guide to Biosafety

        by Edited by George T Tzotzos

        For a number of years the promise of biotechnology has been dimmed by concerns over the intrinsic safety of transgenic organisms. Although considerable knowledge of the properties of recombinant systems and a vast volume of data gathered from different applications of biotechnology are now available, these concerns are still evident. In the developing world, there are also fears that such countries might be used as testing grounds for recombinant products. Considerations of this nature have often overshadowed the benefits these countries might derive from the application of genetic engineering. In response to these concerns, UNIDO, together with the United Nations Environment Programme and the World Health Organization, formed in 1985 the Informal Working Group on Biosafety. In 1991 the Food and Agriculture Organization of the United Nations also joined the Group. The present volume was commissioned by the Group and is intended to help scientists and regulators to conceptualize the major issues underlying biological safety as well as to understand how these affect policies to regulate biotechnology.

        Biotechnology and Plant Genetic Resources

        Conservation and Use

        by Edited by J A Callow, Brian V Ford-Lloyd, H J Newbury

        Advances in molecular and cell biology have led to the development of a whole range of techniques for manipulating genomes, collectively termed “biotechnology”. Although much of the focus in the plant sciences has been on the direct manipulation of plant genomes, biotechnology has also catalyzed a renewed emphasis on the importance of biological and genetic diversity and its conservation. The methods of biotechnology now permit a greater understanding of both species and genetic diversity in plants, the mechanisms by which that variation is generated in nature, and the significance of that variation in the adaptation of plants to their environment. They allow the development of rapid methods for screening germplasm for specific characters and promote more effective conservation strategies by defining the extent of genetic diversity. Tissue culture-based techniques are available for conserving germplasm that cannot be maintained by more traditional methods. Also sophisticated informatics systems enable information on plant genetics and molecular biology to be cross-related to systematic, ecological and other data through international networks.

        Collecting Plant Genetic Diversity

        Technical Guidelines

        by Kevin Eatwell, Gidona Goodman, Emma Keeble, Anna Meredith, Joanna Hedley. Edited by Luigi Guarino, V R Ramanatha Rao, Robert Reid.

        The case for conserving biodiversity is well established on economic as well as scientific grounds. Biodiversity is essential for sustainable development, adaptation to a changing environment and the continued functioning of the biosphere - indeed, to human survival itself. Plant breeders are dependent upon the availability of a large pool of diverse genetic material represented by local races and wild relatives, since in themselves modern crop varieties provide too restricted a genepool for further breeding. Without the ability to draw from a diverse genetic reservoir, further improvement may not be possible. It is therefore essential that guidance is available on collecting plant germplasm. In recent years it has become evident that there is no single publication that provides the prospective collector of plant germplasm with generic as well as specific, and theoretical as well as practical, information. It was to fill this gap that the International Plant Genetic Resources Institute (IPGRI), together with FAO, IUCN and UNEP, cooperated to produce this book. The volume is a comprehensive reference work and is aimed at both new and experienced collectors as well as those with a general interest in plant genetics, breeding and biodiversity.
