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.
Much research has focused on the basic cellular and molecular biological aspects of stem cells. Much of this research has been fueled by their potential for use in regenerative medicine applications, which has in turn spurred growing numbers of translational and clinical studies. However, more work is needed if the potential is to be realized for improvement of the lives and well-being of patients with numerous diseases and conditions. This book series 'Cell Biology and Translational Medicine (CBTMED)' as part of SpringerNature's longstanding and very successful Advances in Experimental Medicine and Biology book series, has the goal to accelerate advances by timely information exchange. Emerging areas of regenerative medicine and translational aspects of stem cells are covered in each volume. Outstanding researchers are recruited to highlight developments and remaining challenges in both the basic research and clinical arenas. This current book is the eight volume of a continuing series.
History will mark the twenty-first century as the dawn of the age of precise genetic manipulation. Breakthroughs in genome editing are poised to enable humankind to fundamentally transform life on Earth. Those familiar with genome editing understand its potential to revolutionize civilization in ways that surpass the impact of the discovery of electricity and the development of gunpowder, the atomic bomb, or the Internet. Significant questions regarding how society should promote or hinder genome editing loom large in the horizon. And it is up to humans to decide the fate of this powerful technology. Rewriting Nature is a compelling, thought-provoking interdisciplinary exploration of the law, science, and policy of genome editing. The book guides readers through complex legal, scientific, ethical, political, economic, and social issues concerning this emerging technology, and challenges the conventional false dichotomy often associated with science and law, which contributes to a growing divide between both fields.
This comprehensive research book represents the first complete integration of current knowledge in this area. It addresses issues associated with poultry breeding particularly by examining quantitative and molecular genetics and the uses of transgenic technology. A special section covers the important area of disease resistance and transmission
The genotype/phenotype dichotomy is being slowly replaced by a more complex relationship whereby the majority of phenotypes arise from interactions between one's genotype and the environment in which one lives. Interestingly, it seems that not only our lives, but also our ancestors' lives, determine how we look. This newly recognized form of inheritance is known as (epi)genetic, as it involves an additional layer of information on top of the one encoded by the genes. Its discovery has constituted one of the biggest paradigm shifts in biology in recent years. Understanding epigenetic factors may help explain the pathogenesis of several complex human diseases (such as diabetes, obesity and cancer) and provide alternative paths for disease prevention, management and therapy. This book introduces the reader to the importance of the environment for our own health and the health of our descendants, sheds light on the current knowledge on epigenetic inheritance and opens a window to future developments in the field.
This book describes the current state of international grape genomics, with a focus on the latest findings, tools and strategies employed in genome sequencing and analysis, and genetic mapping of important agronomic traits. It also discusses how these are having a direct impact on outcomes for grape breeders and the international grape research community. While V. vinifera is a model species, it is not always appreciated that its cultivation usually requires the use of other Vitis species as rootstocks. The book discusses genetic diversity within the Vitis genus, the available genetic resources for breeding, and the available genomic resources for other Vitis species. Grapes (Vitis vinifera spp. vinifera) have been a source of food and wine since their domestication from their wild progenitor (Vitis vinifera ssp. sylvestris) around 8,000 years ago, and they are now the world's most valuable horticultural crop. In addition to being economically important, V. vinifera is also a model organism for the study of perennial fruit crops for two reasons: Firstly, its ability to be transformed and micropropagated via somatic embryogenesis, and secondly its relatively small genome size of 500 Mb. The economic importance of grapes made V. vinifera an obvious early candidate for genomic sequencing, and accordingly, two draft genomes were reported in 2007. Remarkably, these were the first genomes of any fruiting crop to be sequenced and only the fourth for flowering plants. Although riddled with gaps and potentially omitting large regions of repetitive sequences, the two genomes have provided valuable insights into grape genomes. Cited in over 2,000 articles, the genome has served as a reference in more than 3,000 genome-wide transcriptional analyses. Further, recent advances in DNA sequencing and bioinformatics are enabling the assembly of reference-grade genome references for more grape genotypes revealing the exceptional extent of structural variation in the species.

The early promise of genetic engineering triggered a host of social and political concerns. In Molecular Politics, Susan Wright draws on government records, archival materials, and a wide range of interviews to analyze how the American and British governments responded to these concerns and to the struggles among corporations, scientists, universities, trade unions, and public interest groups for control of this controversial technology. Advancing an original approach to the expression of power in policymaking, she provides the first comparative study of a crucial set of policy decisions and explores their implications for the political economy of contemporary science.
Synthetic biology offers powerful remedies for some of the world's most intractable problems, but these solutions are clouded by uncertainty and risk that few strategies are available to address. The incentives for continued development of this emerging technology are prodigious and obvious, and the public deserves assurances that all potential downsides are duly considered and minimized accordingly. Incorporating social science analysis within the innovation process may impose constraints, but its simultaneous support in making the end products more acceptable to society at large should be considered a worthy trade-off. Contributing authors in this volume represent diverse perspectives related to synthetic biology's social sciences, and reflect on different areas of risk analysis and governance that have developed for the field. Such perspectives include leading scholarly discussion pertaining to risk assessment, governance, ethics, and communication. The chapters of this volume note that while the first twenty years of synthetic biology development have focused strongly on technological innovation and product development, the next twenty should emphasize the synergy between developers, policymakers, and publics to generate the most beneficial, well governed, and transparent technologies and products possible. Many chapters in this volume provide new data and approaches that demonstrate the feasibility for multi-stakeholder efforts involving policymakers, regulators, industrial developers, workers, experts, and societal representatives to share responsibilities in the production of effective and acceptable governance in the face of uncertain risk probabilities. A full consideration of such perspectives may prevent a world of draconian regulations based on an insufficient or incomplete understanding of the science that underpins synthetic biology, as well as any hesitancy or fear by the public to adopt its eventual products.
This book presents a historicised account of the Feminist International Network of Resistance to Reproductive and Genetic Engineering (FINRRAGE), a coordinated effort during the 1980s and 1990s by an international group of women to create and disseminate feminist knowledge about the then-new field of reproductive technologies. Bringing insights from science and technology studies together with social movements and feminist theory, it seeks to examine larger questions about knowledge and expertise in activist engagements with rapidly-developing technologies, as well as explore an important and neglected episode of feminist history. Its findings will be relevant to scholars in science studies, gender and women's studies and social movements, as well as to anyone with an interest in reproductive technologies and the history of feminist activism.
This book reviews the chemical, regulatory, and physiological mechanisms of protein arginine and lysine methyltransferases, as well as nucleic acid methylations and methylating enzymes. Protein and nucleic acid methylation play key and diverse roles in cellular signalling and regulating macromolecular cell functions. Protein arginine and lysine methyltransferases are the predominant enzymes that catalyse S-adenosylmethionine (SAM)-dependent methylation of protein substrates. These enzymes catalyse a nucleophilic substitution of a methyl group to an arginine or lysine side chain nitrogen (N) atom. Cells also have additional protein methyltransferases, which target other amino acids in peptidyl side chains or N-termini and C-termini, such as glutamate, glutamine, and histidine. All these protein methyltransferases use a similar mechanism. In contrast, nucleic acids (DNA and RNA) are substrates for methylating enzymes, which employ various chemical mechanisms to methylate nucleosides at nitrogen (N), oxygen (O), and carbon (C) atoms. This book illustrates how, thanks to there ability to expand their repertoire of functions to the modified substrates, protein and nucleic acid methylation processes play a key role in cells.
This book provides in-depth insights into the regulatory frameworks of five countries and the EU concerning the regulation of genome edited plants. The country reports form the basis for a comparative analysis of the various national regulations governing genetically modified organisms (GMOs) in general and genome edited plants in particular, as well as the underlying regulatory approaches.The reports, which focus on the regulatory status quo of genome edited plants in Argentina, Australia, Canada, the EU, Japan and the USA, were written by distinguished experts following a uniform structure. On this basis, the legal frameworks are compared in order to foster a rational assessment of which approaches could be drawn upon to adjust, or to completely realign, the current EU regime for GMOs. In addition, a separate chapter identifies potential best practices for the regulation of plants derived from genome editing.
The book focuses on the evolutionary impact of horizontal gene transfer processes on pathogenicity, environmental adaptation and biological speciation. Newly acquired genetic material has been considered as a driving force in evolution for prokaryotic genomes for many years, with recent technical developments advancing this field further. However, the extent and implications of gene transfer between prokaryotes and eukaryotes still raise controversies. This multi-authored volume introduces various means by which DNA can be exchanged, covers gene transfer between prokaryotes and their viruses as well as between bacteria and eukaryotes, such as fungi, plants and animals, and addresses the role of horizontal gene transfer in human diseases. Aspects discussed also include the relevance for virulence and drug resistance development on one hand, and for the occurrence of naturally derived antibiotics and other secondary metabolites on the other hand. This book offers new insights to anyone interested in genome evolution and the exchange of DNA between the different domains of life, the genetic toolkit for adaptation and the emergence of multidrug resistant bacteria.
Plant tissue culture and advanced biotechnologies have proven to be influential tools that complement conventional breeding and accelerate development of many medicinal plants. Various approaches, such as pathway engineering, precursor feeding, transformation, elicitation with biotic and abiotic elicitors and scaling up in bioreactors, have been explored to improve the production of secondary metabolites from different medicinal plants. This book provides a comprehensive description of various studies, carried out on in vitro culture and hairy root cultures of Catharanthus roseus, Silybum marianum and Digitalis species which have been considered as alternative sources for the production of anti-tumour compounds, flavonolignans and cardenolides. Specific focus is on elicitation strategy for increasing production of bioactive compounds of C. roseus L., S. marianum and Digitalis species to overcome the constrains of conventional propagation. This book is valuable for researchers or students working on medicinal plants, phytochemistry, and plant tissue culture. It also serves as a reference for the pharmaceutical industry.
Bringing together the ideas of experts from around the world, this incisive text offers cutting-edge perspectives on the risk analysis and governance of genetically modified organisms (GMOs), supporting effective and informed decision-making in developing countries. Comprised of four comprehensive sections, this book covers: integrated risk analysis and decision making, giving an overview of the science involved and examining risk analysis methods that impact decision-making on the release of GMOs, particularly in developing countries; diversification of expertise involved in risk analysis and practical ways in which the lack of expertise in developing countries can be overcome; risk analysis based regulatory systems and how they can be undermined by power relationships and socio-political interests, as well as strategies for improving GMO policy development and regulatory decision-making; and case studies from developing countries providing lessons based on real-world experience that can inform our current thinking.
This book sheds new light on the chickpea genome sequencing and resequencing of chickpea germplasm lines and provides insights into classical genetics, cytogenetics, and trait mapping. It also offers an overview of the latest advances in genome sequencing and analysis. The growing human population, rapid climate changes and limited amounts of arable land are creating substantial challenges in connection with the availability and affordability of nutritious food for smallholder farmers in developing countries. In this context, climate smart crops are essential to alleviating the hunger of the millions of poor and undernourished people living in developing countries. In addition to cereals, grain legumes are an integral part of the human diet and provide sustainable income for smallholder farmers in the arid and semi-arid regions of the world. Among grain legumes, the chickpea (Cicer arietinum) is the second most important in terms of production and productivity. Besides being a rich source of proteins, it can fix atmospheric nitrogen through symbiosis with rhizobia and increase the input of combined nitrogen. Several abiotic stresses like drought, heat, salinity, together with biotic stresses like Fusarium wilt, Ascochyta blight, and Botrytis grey mould have led to production losses, as the chickpeas is typically grown in the harsh climates of our planet's semi-arid regions.
This thesis reports on the development of a fully integrated and automated microsystem consisting of low-cost, disposable plastic chips for DNA extraction and PCR amplification, combined with a reusable glass capillary array electrophoresis chip, which can be employed in a modular-based format for genetic analysis. In the thesis, DNA extraction is performed by adopting a filter paper-based method, followed by an "in-situ" PCR carried out directly in the same reaction chamber of the chip without elution. PCR products are then co-injected with sizing standards into separation channels for detection using a novel injection electrode. The entire process is automatically carried out by a custom-made compact control and detection instrument. The author thoroughly tests the system's performance and reliability by conducting rapid genetic screening of mutations on congenital hearing loss and pharmacogenetic typing of multiple warfarin-related single-nucleotide polymorphisms. The successful development and operation of this microsystem establishes the feasibility of rapid "sample-in-answer-out" testing in routine clinical practice.
This book describes specific, well-know controversies in the genetic modification debate and connects them to deeper philosophical issues in philosophy of technology. It contributes to the current, far-reaching deliberations about the future of food, agriculture and society. Controversies over so-called Genetically Modified Organisms (GMOs) regularly appear in the press. The biotechnology debate has settled into a long-term philosophical dispute. The discussion goes much deeper than the initial empirical questions about whether or not GM food and crops are safe for human consumption or pose environmental harms that dominated news reports. In fact, the implications of this debate extend beyond the sphere of food and agriculture to encompass the general role of science and technology in society. The GM controversy provides an occasion to explore important issues in philosophy of technology. Researchers, teachers and students interested in agricultural biotechnology, philosophy of technology and the future of food and agriculture will find this exploration timely and thought provoking.
During the past 15 years, cellular and molecular approaches have emerged as valuable adjuncts to supplement and complement conventional breeding methods for a wide variety of crop plants. Biotechnology increasingly plays a role in the creation, conservation, characterization and utilization of genetic variability for germplasm enhancement. For instance, anther/microspore culture, somaclonal variation, embryo culture and somatic hybridization are being exploited for obtaining incremental improvement in the existing cultivars. In addition, genes that confer insect- and disease-resistance, abiotic stress tolerance, herbicide tolerance and quality traits have been isolated and re-introduced into otherwise sensitive or susceptible species by a variety of transgenic techniques. Together these transformative methodologies grant access to a greater repertoire of genetic diversity as the gene(s) may come from viruses, bacteria, fungi, insects, animals, human beings, unrelated plants or even be artificially derived. Remarkable achievements have been made in the production, characterization, field evaluation and commercialization of transgenic crop varieties worldwide. Likewise, significant advances have been made towards increasing crop yields, improving nutritional quality, enabling crops to be raised under adverse conditions and developing resistance to pests and diseases for sustaining global food and nutritional security. The overarching purpose of this 3-volume work is to summarize the history of crop improvement from a technological perspective but to do so with a forward outlook on further advancement and adaptability to a changing world. Our carefully chosen "case studies of important plant crops" intend to serve a diverse spectrum of audience looking for the right tools to tackle complicated local and global issues.
This book analyzes the impacts of current and possible future GM crop applications and shows that these technologies can contribute substantially to sustainable agricultural development and food security.

This thesis outlines the development of the very first technology for high-throughput analysis of paired heavy and light-chain antibody sequences, opening an entirely new window for antibody discovery and the investigation of adaptive immune responses to vaccines and diseases. Previous methods for high-throughput immune repertoire sequencing have been unable to provide information on the identity of immune receptor pairs encoded by individual B or T lymphocytes. The author directly addresses these limitations by designing two new technologies for sequencing multiple mRNA transcripts from up to 10 million isolated, single cells. The techniques developed in this work have enabled comprehensive interrogation of human B-cell repertoires and have been applied for rapid discovery of new human antibodies, to gain new insights into the development of human antibody repertoires, and for analysis of human immune responses to vaccination and disease. |
