During the past five to ten years, a variety of tools has been developed in the disciplines of both gene engineering, and molecular and structural biology. Some of these advances have permitted scientists not only to identify and characterize genes, but also to target these genes by disruption, thus eliminating their function in living animals, and to det- mine the biological responses to altered gene products. This has particular significance in endocrine systems, in which feedback mechanisms between the hypothalamus, pi- itary, and end organs are critical in normal physiology. Interpretation of the physiological significance, or the site of action of specific molecules in this context, has been difficult prior to transgenic technology. Major advances have occurred specifically in the areas of growth and development, and of reproduction. Coupled with analysis of naturally occurring mutations in humans, the use of transgenic animals and in vitro systems has recently allowed endocrinologists to understand the importance of specific thyroid hormone receptor isoforms in vivo, the molecular basis for generalized resistance to thyroid hormones via mutations in the nuclear receptor, and mechanisms for suppressing gene transcription. Previously designated "orphan rec- tors," such as steroidogenic factor-1, were demonstrated to have critical roles in dev- opment and reproduction. Other nuclear receptors-including those for thyroid hormone, estrogens, androgens, and progesterone-were shown to bind to coactivator and co- pressor proteins that modified their transcriptional activity, and contributed to the ce- specific effects of the hormones.

Mammalian and Avian Transgenesis presents a collection of novel methods for the production of a wide range of transgenic animals. The manual focuses largely on mice, but also contains protocols for successful transgenesis in rats, cows, pigs and birds.

The manual provides detailed, step-by-step protocols covering all aspects of the production of transgenic animals, including the use of lentiviral vectors in gene transfer, intracytoplasmic sperm injection, nuclear transfer, large insert transgenesis, conditional gene expression systems, the use of reporter genes in transgenesis and transgenesis in large animals and birds. The text is supplemented by superb color photos. While the focus is on newly established techniques, the fundamental methods of transgenesis are also covered for those new to the field. Thus this manual is perfectly suited for those wishing to adopt new technologies in transgenesis.

Biolistic transfection represents a direct physical gene transfer approach in which nucleic acids are precipitated on biologically inert high-density microparticles (usually gold or tungsten) and delivered directly through cell walls and/or membranes into the nucleus of target cells by high-velocity acceleration using a ballistic device such as the gene gun.

This book focuses on the importance and roles of seed microbiomes in sustainable agriculture by exploring the diversity of microbes vectored on and within seeds of both cultivated and non-cultivated plants. It provides essential insights into how seeds can be adapted to enhance microbiome vectoring, how damaged seed microbiomes can be assembled again and how seed microbiomes can be conserved. Plant seeds carry not only embryos and nutrients to fuel early seedling growth, but also microbes that modulate development, soil nutrient acquisition, and defense against pathogens and other stressors. Many of these microbes (bacteria and fungi) become endophytic, entering into the tissues of plants, and typically exist within plants without inducing negative effects. Although they have been reported in all plants examined to date, the extent to which plants rely on seed vectored microbiomes to enhance seedling competitiveness and survival is largely unappreciated. How microbes function to increase the fitness of seedlings is also little understood. The book is a unique and important resource for researchers and students in microbial ecology and biotechnology. Further, it appeals to applied academic and industrial agriculturists interested in increasing crop health and yield.

This book addresses emerging questions concerning who should bear responsibility for shouldering risk, as well as the viability of existing and experimental governance mechanisms in connection with new technologies. Scholars from 14 jurisdictions unite their efforts in this edited collection to provide a comparative analysis of how various legal systems are tackling the challenges produced by the legal aspects of genetic testing in insurance and employment. They cover the diverse set of norms that surround this issue, and share insights into relevant international, regional and national incursions into the field. By doing so, the authors offer a basis for comparative reflection, including on whether transnational standard setting might be useful or necessary for the legal aspects of genetic testing as they relate to the insurance and employment contexts. The respective texts cover a broad range of topics, including the prevalence of genetic testing in the contexts of insurance and employment, and policy factors that might affect this prevalence, such as the design of national health or social insurance systems, of private insurance schemes or the availability of low-cost direct-to-consumer genetic testing. Further, the field of genetics is gaining in importance at the international and regional levels. Relevant concepts - mainly genetic tests and genetic data/information - have been internationally defined, and these definitions have influenced definitions adopted nationally. International law also recognizes a "special status" for human genetic data. The authors therefore also consider these definitions and the recognition of the special status of human genetic data within regional and national legal orders. They investigate the range of norms that specifically address the use of genetic testing in employment and insurance, encompassing international sources - including human rights norms - that may be binding or non-binding, as well national statutory, regulatory and soft-law mechanisms. Accordingly, some of the texts examine general frameworks relevant to genetic testing in each country, including those that stem from general anti-discrimination rules and norms protecting rights to autonomy, self-determination, confidentiality and privacy. In closing, the authors provide an overview of the efficiency of their respective legal regimes' approaches - specific and generalist - to genetic testing or disclosure of genetic information in the employment or insurance contexts, including the effect of lack of legal guidance. In this regard, some of the authors highlight the need for transnational action in the field and make recommendation for future legal developments.

Jatropha curcas, or physic nut, is a small tree that, in tropical climates, produces fruits with seeds containing ~38% oil. The physic nut has the potential to be highly productive and is amenable to subculture in vitro and to genetic modification. It also displays remarkable diversity and is relatively easy to cross hybridize within the genus. Thanks to these promising features, J. curcas is emerging as a promising oil crop and is gaining commercial interest among the biofuel research communities. However, as a crop, physic nut has been an economic flop since 2012, because the species was not fully domesticated and the average productivity was less than 2 t/ha, which is below the threshold of profitability.^7 t/ha could be reached and it is contributing to new markets in some countries. As such, it is important fro research to focus on the physiology and selective breeding of Jatropha . This book provides a positive global update on Jatropha, a crop that has suffered despite its promising agronomic and economic potential. The editors have used their collective expertise in agronomy, botany, selective breeding, biotechnology, genomics and bioinformatics to seek out high-quality contributions that address the bottleneck features in order to improve the economic trajectory of physic nut breeding.

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.

Climate Change and Food Security with Emphasis on Wheat is the first book to present the full scope of research in wheat improvement, revealing the correlations to global issues including climate change and global warming which contribute to food security issues. Wheat plays a key role in the health of the global economy. As the world population continuously increases, economies modernize, and incomes rise, wheat production will have to increase dramatically to secure it as a reliable and sustainable food source. Since covering more land area with wheat crops is not a sustainable option, future wheat crops must have consistently higher yields and be able to resist and/or tolerate biotic and abiotic stresses that result from climate change. Addressing the biophysical and socioeconomic constraints of producing high-yielding, disease-resistant, and good quality wheat, this book will aid in research efforts to increase and stabilize wheat production worldwide. Written by an international team of experts, Climate Change and Food Security with Emphasis on Wheat is an excellent resource for academics, researchers, and students interested in wheat and grain research, especially as it is relevant to food security.

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.

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.

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.

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 Transformation via Agrobacterium Tumefaciens compiles fundamental and specific information and procedures involving in vitro soybean transformation, which forms the basis for the Agrobacterium-mediated genetic manipulation of soybean using plant tissue culture. This method serves as one of the most preferred, reliable and cost-effective mechanism of transgene expression in both leguminous recalcitrant species and non-legume crops. The technology is favoured due to its simplicity, feasibility and high transformation rates that are so far achieved mostly in monocot plants and a few dicot genotypes. This book provides a comprehensive review of plant transformation which remains necessary for many researchers who are still facing protocol-related hurdles. Among some of the major topics covered in Plant Transformation via Agrobacterium Tumefaciens are the history and discovery of Agrobacterium bacterium, longstanding challenges causing transformation inefficiencies, types and conditions of explants, development of transgenic plants for stress resistance, and the role of transgenic plants on animal/human health, including the environment. Plant Transformation via Agrobacterium Tumefaciens helps the reader to understand how soybean, like many other orphan legume crops, faces the risk of overexploitation which may render the currently available varieties redundant and extinct should its narrow gene pool not improve. Plant transformation serves as a key technique in improving the gene pool, while developing varieties that are drought tolerant, have enhanced nutritional value, pest resistant and reduce the destruction by disease causing microorganims. This book is an essential foundation tool that is available for researchers and students to reinforce the application of Agrobacterium-mediated genetic transformation in soybean.
