QTL Mapping in Crop Improvement: Present Progress and Future Perspectives presents advancements in QTL breeding for biotic and abiotic stresses and nutritional improvement in a range of crop plants. The book presents a roadmap for future breeding for resilience to various stresses and improvement in nutritional quality. Crops such as rice, wheat, maize, soybeans, common bean, and pigeon pea are the major staple crops consumed globally, hence fulfilling the nutritional requirements of global populations, particularly in the under-developed world, is extremely important. Sections cover the challenges facing maximized production of these crops, including diseases, insect damage, drought, heat, salinity and mineral toxicity. Covering globally important crops including maize, wheat, rice, barley, soybean, common bean and pigeon pea, this book will be an important reference for those working in agriculture and crop improvement.

This book provides a review of imaging techniques and applications in stem cell transplantation and other cell-based therapies. The basis of different molecular imaging techniques is explained in detail, as is the current state of interventional radiology techniques. While the whole is a comprehensive discussion, each chapter is self-sufficient enough so that each can be reviewed independently. The contributors represent years of international and cross-disciplinary expertise and perspective and are all well known in their fields. comprehensive information on the role of clinical and molecular imaging in stem cell therapy from this book reviewed in detail. Essential reading for radiologists and physicians who are interested in developing a basic understanding of stem cell imaging and applications of stem cells and cell based therapies. However, it will also be of interest to clinical scientists and researchers alike, including those involved in stem cell labeling, tracking & imaging, cancer therapy, angiogenesis and cardiac regeneration.

This book defines the field of systems biology, one of the newest and fastest developing fields in science today. It discusses the most effective experimental and computational strategies and highlights new and emerging applications. Cell biologists and other readers will discover many benefits for industry, such as the new network-based drug-target design validation. The authors also thoroughly explore testing.

This volume reflects on the effects of recent discoveries in genetics on a broad range of scientific fields. In addition to neuroscience, evolutionary biology, anthropology and medicine, contributors analyze the effects of genetics on theories of health, law, epistemology and philosophy of biology. Social and moral concerns about the relationship between genetics, society and the individual also figure prominently. Genetic discoveries fuel central contemporary public policy debates concerning, for example, human cloning, equitable access to healthcare or the role of genetics in medicine. Perhaps more fundamentally, advances in genetics are altering our perception of human life and death.

The field of DNA vaccines has undergone explosive growth in the last few years. As usual, some historical precursors of this approach can be d- cerned in the scientific literature of the last decades. However, the present state of affairs appears to date from observations made discreetly in 1988 by Wolff, Malone, Felgner, and colleagues, which were described in a 1989 patent and published in 1990. Quite surprisingly, they showed that genes carried by pure plasmid DNA and injected in a saline solution, hence the epithet "naked DNA," could be taken up and expressed by skeletal muscle cells with a low but reproducible frequency. Such a simple methodology was sure to spawn many applications. In a separate and important line of experimentation, Tang, De Vit, and Johnston announced in 1992 that it was indeed possible to obtain humoral immune responses against proteins encoded by DNA delivered to the skin by a biolistic device, which has colloquially become known as the "gene gun. " The year 1993 saw the publication of further improvements in the me- ods of naked DNA delivery and, above all, the first demonstrations by several groups of the induction of humoral and cytotoxic immune responses to viral antigens expressed from injected plasmid DNA. In some cases, protection against challenge with the pathogen was obtained. The latter result was - questionably the touchstone of a method of vaccination worthy of the name.

Nano-enabled Sustainable and Precision Agriculture is the first single-volume resource to cover this important field using a whole systems approach that considers both opportunities and challenges. The book provides a comprehensive understanding of the role of nanotechnology in agriculture from broad aspects, but also includes a comprehensive view of the interaction of nanomaterials with soil-plant systems. It highlights aspects not described in previous books, including the application of nanoinformatics and artificial intelligence in nano-enabled sustainable agriculture, the application of nanotechnology in alternative forms of agriculture such as hydroponics, and regulatory frameworks for this research field. The book addresses all these aspects by including sections on enhanced sustainability, reduced pollution and enhanced ecosystems' health, and the role of nanoinformatics and machine learning.

A timely book for DNA researchers, Automated DNA Sequencing and Analysis reviews and assesses the state of the art of automated DNA sequence analysis-from the construction of clone libraries to the developmentof laboratory and community databases. It presents the methodologies and strategies of automated DNA sequence analysis in a way that allows them to be compared and contrasted. By taking a broad view of the process of automated sequence analysis, the present volume bridges the gap between the protocols supplied with instrument and reaction kits and the finalized data presented in the research literature. It will be an invaluable aid to both small laboratories that are interested in taking maximum advantageof automated sequence resources and to groups pursuing large-scale cDNA and genomic sequencing projects.
* The field of automation in DAN sequencing and analysis is rapidly moving. Hovever, as the technology becomes commonplace, those applying the techniques involved to their research fields need a text which both expands on the protocols supplied by manufacturers with their instruments and explains how to utilise the data produced. This book fulfils those needs, reviews the history of the art and provides pointers to future development.

After decades of systematic collection of data describing age-related changes in organisms, organs, tissues, cells and macromolecules, biogerontologists are now in a position to construct general principles of ageing and explore various possibilities of intervention using rational approaches. While not giving serious consideration to the claims made by charlatans, it cannot be ignored that several researchers are making genuine attempts to test and develop various means of intervention for the prevention and treatment of age-related diseases, for regaining the functional abilities and for prolonging the lifespan of experimental organisms. This book provides the most up-to-date information and a critical evaluation of a variety of approaches being tried for modulating aging and longevity, including dietary supplementation with antioxidants, vitamins and hormones, genetic engineering, life-style alterations, and hormesis through mild stress. The goal of research on ageing is not to increase human longevity regardless of the consequences, but to increase active longevity free from disability and functional dependence.

Statistics is strongly tied to applications in different scientific disciplines, and the most challenging statistical problems arise from problems in the sciences. In fact, the most innovative statistical research flows from the needs of applications in diverse settings. This volume is a testimony to the crucial role that statistics plays in scientific disciplines such as genetics and environmental sciences, among others. The articles in this volume range from human and agricultural genetic DNA research to carcinogens and chemical concentrations in the environment and to space debris and atmospheric chemistry. Also included are some articles on statistical methods which are sufficiently general and flexible to be applied to many practical situations. The papers were refereed by a panel of experts and the editors of the volume. The contributions are based on the talks presented at the Workshop on Statistics and the Sciences, held at the Centro Stefano Franscini in Ascona, Switzerland, during the week of May 23 to 28, 1999. The meeting was jointly organized by the Swiss Federal Institutes of Technology in Lausanne and Zurich, with the financial support of the Minerva Research Foundation. As the presentations at the workshop helped the participants recognize the po tential role that statistics can play in the sciences, we hope that this volume will help the reader to focus on the central role of statistics in the specific areas presented here and to extrapolate the results to further applications."

Cell culture based research is important for our understanding of biological processes at the cellular and molecular level. Using this approach, the previous decades have produced a wealth of mechanistic information in all areas of biomedical research. Such in vitro research, however, lacks the complexity of in vivo investigations, where many different cell types interact with each other in a normal, three-dimensional environment, with normal levels of cytokines and growth factors. Furthermore, complex human diseases, such as cancer, diabetes or chronic inflammation, can only be modeled in vivo. Due to its small size, its short reproduction time, and the possibility to introduce specific gene mutations, the mouse has become the favourite mammalian model organism to study in vivo function of genes during development and in disease. This book combines review articles on selected subjects presented at the symposium "Mouse as a Model Organism - From Animals to Cells", held in Rovaniemi, Finland, 2009. Among other topics, high-throughput phenotyping of mouse mutants, mouse phenotypes dependent on nature and nuture, and a spectrum of in vivo, ex vivo and in vitro methods to study cancer in mice are described. This book will give an excellent introduction to scientists interested in the use of mice as a model to understand complex biological questions in the post-genomic era. It will highlight the possibilities, but also discuss the current problems and shortcomings, to give a realistic view of the current state-of-art in this fascinating field of biomedical research.

The present volume is a continuation of the EL.B.A. Forum Series, which was initiated in the spring of 1995 with the first volume, entitled From Neural Network and Biomolecular Engineering to Bioelectronics, in which a brief outline of modem bioelectron ics given as "the use of biological materials and biological architectures for information processing and sensing systems and devices down to molecular level. " The present volume highlights the aspects of advanced biotechnology and electronics originating from molecular manufacturing, which has been emerging as an independent branch of research. This volume appears in a crucial moment, when significant progress has already been made in this strategic field and when technologies derived from it are recognized as critical for the welfare of our society. In addition, acknowledging to the Italian Ministry of University and Scientific and Technological Research for launching the National Research Program "Technologies for Bioelectronics" in 1992 and for continuation of support of this advanced multidisciplinary research, we would like to acknowledge the support of the National Research Council of Italy through the "Molecular Manufacturing" CNR Strategic Project since 1994. The significant unique role of Technobiochip in the organization of the EL.B.A. Forums and in bringing to light the enormous industrial potential of bioelectronics is duly acknowledged, as well as its attraction and support of top level scientists to the series of EL.B.A. Forums of which this volume is part.

Over the past 10 years great progress has been made in the development of efficient techniques for both gene isolation and mapping. The identifica- tion and isolation of transcribed sequences from large chromosomal regions are central to the human genome mapping project. Techniques for isolating novel cDNAs have applications both in the overall construction and integra- tion of long-range physical and transcription maps and in the identification of disease genes. A number of different techniques for the isolation of cDNAs from mam- malian genomes have been developed, including screening "zoo" blots, the use of large genomic clones (YACs or cosmids) for hybridization against cDNA libraries, and CpG island mapping. More recently two highly efficient tech- niques have been introduced: exon trapping, based on the presence of exon splice sites, and direct selection, based on the enrichment of selected cDNAs using immobilized YACs or cosmids. Leading researchers in the field have contributed chapters detailing the practical procedures for these and other widely used methods. The most rapid progress presently being made in the field of gene isolation concerns the partial sequencing of cDNA clones from one or both ends to produce expressed sequence tags (ESTs). Indeed, by Octo- ber 1995, the EST division of Genbank (dbEST) contained a total of approxi- mately 270,000 human EST sequences accounting for almost half the number of sequence entries in Genbank.

Developments over the past few years have revealed the remarkable versatility of RNA in any compartment of the cell, tasks that had been thought to be exclusively in the realm of proteins and even beyond. The chapters in this book written by leading investigators in the field provide insight into various promising avenues where RNA and nucleic acid derivatives including antisense RNAs, such as siRNA, miRNAs, amplification/selection (SELEX) generated aptamers as well as ribozymes are at the threshold of impacting medicine.

The first libraries of complementary DNA (cDNA) clones were con structed in the mid-to-late 1970s using RNA-dependent DNA polymerase (reverse transcriptase) to convert poly A* mRNA into double-stranded cDNA suitable for insertion into prokaryotic vectors. Since then cDNA technology has become a fundamental tool for the molecular biologist and at the same time some very significant advances have occurred in the methods for con structing and screening cDNA libraries. It is not the aim of cDNA Library Protocols to give a comprehensive review of all cDNA library-based methodologies; instead we present a series of up-to-date protocols that together should give a good grounding of proce dures associated with the construction and use of cDNA libraries. In deciding what to include, we endeavored to combine up-to-date versions of some of the most widely used protocols with some very usefiil newer techniques. cDNA Library Protocols should therefore be especially useful to the investigator who is new to the use of cDNA libraries, but should also be of value to the more experienced worker. Chapters 1-5 concentrate on cDNA library construction and manipula tion, Chapters 6 and 7 describe means of cloning difficult-to-obtain ends of cDNAs, Chapters 8-18 give various approaches to the screening of cDNA libraries, and the remaining chapters present methods of analysis of cDNA clones including details of how to analyze cDNA sequence data and how to make use of the wealth of cDNA data emerging from the human genome project."

In 1970, Manfred Eigen initiated the study of the origin of self-reproducing systems of macromolecules and their evolution. Large-scale nucleotide sequencing (with computer methods) was introduced from 1977. The authors of this book, the first edition of which appeared (in Russian) in 1985, have been engaged in the research of the evolution of molecular genetic regulatory systems ever since those pioneering years. The book considers many fundamental problems of molecular biology, evolution, molecular genetic organization, the structure and function of macromolecules, always with the underlying motive of developing a unified theory. It describes many original, theoretical results as well as computational methods.

As the major task of sequencing the human genome is near completion and full complement of human genes are catalogued, attention will be focused on the ultimate goal: to understand the normal biological functions of these genes, and how alterations lead to disease states. In this task there is a severe limitation in working with human material, but the mouse has been adopted as the favored animal model because of the available genetic resources and the highly conserved gene conservation linkage organization. In just of ten years since the first gene-targeting experiments were p- formed in embryonic stem (ES) cells and mutations transmitted through the mouse germline, more than a thousand mouse strains have been created. These achievements have been made possible by pioneering work that showed that ES cells derived from preimplantation mouse embryos could be cultured for prolonged periods without differentiation in culture, and that homologous rec- bination between targeting constructs and endogenous DNA occurred at a f- quency sufficient for recombinants to be isolated. In the next few years the mouse genome will be systematically altered, and the techniques for achi- ing manipulations are constantly being streamlined and improved.

PCR Cloning Protocols, Second Edition, updates and expands Bruce White's best-selling PCR Cloning Protocols (1997) with the newest procedures for DNA cloning and mutagenesis. Here the researcher will find readily reproducible methods for all the major aspects of PCR use, including PCR optimization, computer programs for PCR primer design and analysis, and novel variations for cloning genes of special characteristics or origin, with emphasis on long distance PCR and GC-rich template amplification. Also included are both conventional and novel enzyme-free and restriction site-free procedures to clone PCR products into a range of vectors, as well as state-of-the-art protocols to facilitate DNA mutagenesis and recombination, and to clone the challenging uncharacterized DNA flanking a known DNA fragment.

Since its invention and subsequent development nearly 20 years ago, po- merase chain reaction (PCR) has been extensively utilized to identify numerous gene probes in vitro and in vivo. However, attempts to generate complete and full-length complementary cDNA libraries were, for the most part, fruitless and remained elusive until the last decade, when simple and rapid methods were developed. With current decoding and potential application of human genome information to genechips, there are urgent needs for identification of functional significance of these decoded gene sequences. Inherent in bringing these app- cations to fruition is the need to generate a complete and full-length cDNA library for potential functional assays of specific gene sequences. Generation of cDNA Libraries: Methods and Protocols serves as a laboratory manual on the evolution of generation of cDNA libraries, covering both ba- ground information and step-by-step practical laboratory recipes for which p- tocols, reagents, operational tips, instrumentation, and other requirements are detailed. The first chapter of the book is an overview of the basics of generating cDNA libraries, which include the following: (a) the definition of a cDNA library, (b) different kinds of cDNA libraries, (c) differences between methods for cDNA library generation using conventional approaches and novel stra- gies, including reverse generation of RNA repertoires from cDNA libraries, and (d) the quality of cDNA libraries.

A major success story of modem molecular biology is the development of technologies to clone and express specific genes. Current applications of recombinant gene products cover a wide spectrum, including gene therapy, production of bioactive pharmaceuticals, synthesis of novel biopolymers, agriculture and animal husbandry, and so on. Inherent in bringing these appli cations to fruition is the need to design "expression constructs" that will per mit the ready and specific detection and isolation of the defined recombinant gene products. Recombinant Protein Protocols grows out of the need for a laboratory manual on the detection and isolation of recombinantly expressed genes that covers both the background information and the practical laboratory recipes for these analyses. In this book, detailed and contemporary protocols are col lected to provide the reader with a wide-ranging number of methodologies to enhance the detection and isolation of their gene product(s) of interest. A large number of molecular tags and labels and their usage are described, including enzymes, ligand-binding moieties, immunodetectable molecules, as well as methods to detect interactive proteins, and gene expression-mediated alter ations in cellular activity. Chapters on in situ detection of gene expression deal with technologies that are currently being applied to the study of gene function and activity. Highlights of applications for recombinant gene expres sion technologies are provided to give readers exciting perspectives on the future of such technologies.

Part of a review series that looks at trends in modern biology. This book covers aspects of bioprocessing and biotransformation, where knowledge, methods and expertise are required from chemistry, biochemistry, microbiology, genetics, chemical engineering and computer science.

The effort to sequence the human genome is now moving toward a c- clusion. As all of the protein coding sequences are described, an increasing emphasis will be placed on understanding gene function and regulation. One important aspect of this analysis is the study of how transcription factors re- late transcriptional initiation by RNA polymerase II, which is responsible for transcribing nuclear genes encoding messenger RNAs. The initiation of Class II transcription is dependent upon transcription factors binding to DNA e- ments that include the core or basal promoter elements, proximal promoter elements, and distal enhancer elements. General initiation factors are involved in positioning RNA polymerase II on the core promoter, but the complex - teraction of these proteins and transcriptional activators binding to DNA e- ments outside the core promoter regulate the rate of transcriptional initiation. This initiation process appears to be a crucial step in the modulation of mRNA levels in response to developmental and environmental signals. Transcription Factor Protocols provides step-by-step procedures for key techniques that have been developed to study DNA sequences and the protein factors that regulate the transcription of protein encoding genes. This volume is aimed at providing researchers in the field with the well-detailed protocols that have been the hallmark of previous volumes of the Methods in Molecular (TM) Biology series.

This proceedings is based on a joint meeting of the two IUFRO (International Union of Forestry Research Organizations) Working Parties, Somatic Cell Genetics (S2.04-07) and Molecular Genetics (S2.04-06) held in Gent, Belgium, 26-30 September, 1995. Although a joint meeting of the two Working Parties had been discussed in the past, this was the first such meeting that became a successful reality. In fact this meeting provided an excellent forum for discussions and interactions in forest bioteclUlology that encouraged the participants to vote for a next joint meeting. In the past decade rapid progress has been made in the somatic cell genetics and molecular genetics of forest trees. In order to cover recent developments in the broad area of biotechnology, the scientific program of the meeting was divided into several sessions. These included somatic embryogenesis, regeneration, transformation, gene expression, molecular markers, genome mapping, and biotic and abiotic stresses. The regeneration of plants, produced by organogenesis or somatic embryogenesis, is necessary not only for mass cloning of forest trees, but also for its application in genetic transformation and molecular biology. Although micropropagation has been achieved from juvenile tissues in a number of forest tree species, in vitro regeneration from mature trees remains a challenging problem in most hardwoods and conifers. The mechanisms involved in the transition from juvenile to mature phase in woody plants are poorly understood. This transition can now be investigated at the molecular level.
