What are genes? What do genes do? These seemingly simple questions are in fact challenging to answer accurately. As a result, there are widespread misunderstandings and over-simplistic answers, which lead to common conceptions widely portrayed in the media, such as the existence of a gene 'for' a particular characteristic or disease. In reality, the DNA we inherit interacts continuously with the environment and functions differently as we age. What our parents hand down to us is just the beginning of our life story. This comprehensive book analyses and explains the gene concept, combining philosophical, historical, psychological and educational perspectives with current research in genetics and genomics. It summarises what we currently know and do not know about genes and the potential impact of genetics on all our lives. Making Sense of Genes is an accessible but rigorous introduction to contemporary genetics concepts for non-experts, undergraduate students, teachers and healthcare professionals.

Louis-Marie Houdebine and Jianglin Fan The study of biological functions of proteins and their possible roles in the pathogenesis of human diseases requires more and more relevant animal m- els. Although mice including genetically modified mice offer many possibilities, other non-murine species are absolutely required in some circumstances. Rabbit is one of these species, which has been widely used in biomedical studies. This animal is genetically and physiologically closer to humans including cardiov- cular system and metabolism characteristics. Rabbit is thus more appropriate than mice to study some diseases such as atherosclerosis and lipid metabolism. Because of its larger size, surgery manipulation, bleeding, and turn-over studies are much easier performed in rabbits than in mice. Furthermore, transgenic rabbits can be produced using microinjection and other methods such as lentiviral v- tors. Cloning in rabbits has been proved possible, even though still laborious and time-consuming. Hopefully, functional rabbit ES cell lines will be available in the coming years. Gene deletion or knock-out in rabbits will then become possible.

Summarizing landmark research, Volume 2 of this essential series furnishes information on the availability of germplasm resources that breeders can exploit for producing high-yielding cereal crop varieties. Written by leading international experts, this volume offers the most comprehensive and up-to-date information on employing genetic resources to increase the yield of those cereal crops that provide the main source of nutrition for two-thirds of the world. In thirteen succinct chapters, Genetic Resources, Chromosome Engineering, and Crop Improvement: Cereals, Volume 2 focuses on wheat, rice, maize, oats, barley, millet, sorghum, and rye, as well as triticale: a wheat and rye hybrid with great potential. An introductory chapter outlines the cytogenetic architecture of cereal crops, describes the principles and strategies of cytogenetics and breeding, and summarizes landmarks in current research. This sets the stage for the ensuing crop-specific chapters. Each chapter generally provides a comprehensive account of the crop, its origin, wild relatives, exploitation of genetic resources in the primary, secondary, and tertiary gene pools through breeding and cytogenetic manipulation, and genetic enrichment using the tools of molecular genetics and biotechnology. Certain to become the standard reference for improving the yields of these critical grains, this book is the definitive source of information for plant breeders, agronomists, cytogeneticists, taxonomists, molecular biologists, biotechnologists, and graduate students and researchers in these fields.

DNA replication is arguably the most crucial process at work in living cells. It is the mechanism by which organisms pass their genetic information from one generation to the next and life on Earth would be unthinkable without it. Despite the discovery of DNA structure in the 1950s, the mechanism of its replication remains rather elusive. This work makes important contributions to this line of research. In particular, it addresses two key questions in the area of DNA replication: which evolutionary forces drive the positioning of replication origins in the chromosome and how is the spatial organization of replication factories achieved inside the nucleus of a cell?. A cross-disciplinary approach uniting physics and biology is at the heart of this research. Along with experimental support, statistical physics theory produces optimal origin positions and provides a model for replication fork assembly in yeast. Advances made here can potentially further our understanding of disease mechanisms such as the abnormal replication in cancer.

Synthetic Biology is already an object of intensive debate. However, to a great extent the discussion to date has been concerned with fundamental ethical, religious and philosophical questions. By contrast, based on an investigation of the field’s scientific and technological character, this book focuses on new functionalities provided by synthetic biology and explores the associated opportunities and risks. Following an introduction to the subject and a discussion of the most central paradigms and methodologies, the book provides an overview of the structure of this field of science and technology. It informs the reader about the current stage of development, as well as topical problems and potential opportunities in important fields of application. But not only the science itself is in focus. In order to investigate its broader impact, ecological as well as ethical implications will be considered, paving the way for a discussion of responsibilities in the context of a field at a transitional crossroads between basic and applied science. In closing, the requirements for a suitable regulatory framework are discussed. The book is intended as a source of information and orientation for researchers, students and practitioners in the natural sciences and technology assessment; for members of scientific and technological, governmental and funding institutions; and for members of the general public interested in essential information on the current status, prospects and implications of synthetic biology.

I entered the gene therapy field in the mid-1990s, being fascinated by the immense potential of genes as drugs for the treatment of human disease. Since then, I have experienced the ups and downs of this discipline, and tried to contribute with my work and that of my laboratory to the development of innovative approaches to the treatment of cardiovascular disorders. During these years, I have had several opp- tunities to speak on gene therapy at lectures and academic lessons, and have often noticed that the field is very attractive to scientists of all disciplines. However, as yet no comprehensive book on the subject has been published. Indeed, most books in the field are either a collection of gene transfer laboratory protocols or deal with the subject in a rather superficial manner. Hence the idea to write a gene therapy textbook that is broad and comprehensive, but at the same time provides sufficient molecular and clinical detail to be of interest to students, professors, and specialists in the various disciplines that contribute to gene therapy. I have tried to keep the language plain and, whenever possible, non-technical. Since the book is intended to be a textbook in the field of gene therapy in both the basic science and clinical areas, whenever technical descriptions are required, they are provided.

While the WTO agreements do not regulate the use of biotechnology per se, their rules can have a profound impact on the use of the technology for both commercial and non-commercial purposes. This book seeks to identify the challenges to international trade regulation that arise from biotechnology. The contributions examine whether existing international obligations of WTO Members are appropriate to deal with the issues arising for the use of biotechnology and whether there is a need for new international legal instruments, including a potential WTO Agreement on Biotechnology. They combine various perspectives on and topics relating to genetic engineering and trade, including human rights and gender; intellectual property rights; traditional knowledge and access and benefit sharing; food security, trade and agricultural production and food safety; and medical research, cloning and international trade.

In February 2001, two separate teams published the first working drafts of the entire human genome, marking an achievement that is certainly one of the seminal developments in our understanding of human biology. A grasp of the function of each gene will radically change how we diagnose and prevent diseases and adminster treatments. But the drive to turn the completed sequence into practical knowledge is fraught with complexity. This volume, a summary of the eponymous symposium, gives the student and practitioner alike insight into some of the challenges this new science faces and the lessons it has already taught us. Included are presentations by several leading experts in the field, among them Ian Dunham and Jean Weissenbach.

Synthetic Biology (SB) is a revolutionary discipline with a vast range of practical applications, but is SB research really based on engineering principles? Does it contributing to the artificial synthesis of life or does it utilise approaches sufficiently advanced to fall outside the scope of biotechnology or metabolic engineering? This volume reviews the development of SB and includes the major milestones of the discipline, the 'top-down' and 'bottom-up' approaches towards the construction of an artificial cell and the development of the "iGEM" competition. We conclude that SB is an emerging field with extraordinary technological potential, but that most research projects actually are an extension of metabolic engineering since the complexity of living organisms, their tight dependence on evolution and our limited knowledge of the interactions between the molecules, actually make life difficult to engineer.

TwentyyearshavegonebysinceJackSokatch?rstpublishedhisoutsta- ingTheBiologyofPseudomonasbackin1986.Thiswasfollowedbytwobooks published by the ASM that contained the presentations of the Pseudomonas meetings held in Chicago in 1989 and Trieste in 1991. The earlier volume of these two was edited by Simon Silver, Al Chakrabarty, Barbara Iglewski, and Sam Kaplan, and the later one by Enrica Galli, Simon Silver, and Bernard Witholt. The time was ripe for a series of books on Pseudomonas because of its importance in human and plant pathogenesis, bio?lms, soil and rhizosphere colonization, etc. Efforts were devoted to produce the ?rst three volumes of the series on the biology of Pseudomonas after a meeting with Kluwer staff members in August 2002 during the XI IUMS conference in Paris (France). In less than a year a group of outstanding scientists in the ?eld, after devoting much of their valuable time, managed to complete their chapters for the three volumes of the series. To ensure the high standard of each chapter, renowned scientists participated in the reviewing process. The three books collected part of the "explosion" of new vital information on the genus Pseudomonas.

Massive data acquisition technologies, such as genome sequencing, high-throughput drug screening, and DNA arrays are in the process of revolutionizing biology and medicine. Using the mRNA of a given cell, at a given time, under a given set of conditions, DNA microarrays can provide a snapshot of the level of expression of all the genes in the cell. Such snapshots can be used to study fundamental biological phenomena such as development or evolution, to determine the function of new genes, to infer the role individual genes or groups of genes may play in diseases, and to monitor the effect of drugs and other compounds on gene expression. Originally published in 2002, this inter-disciplinary introduction to DNA arrays will be of value to anyone with an a interest in this powerful technology.

Over the past decade, our laboratory and others have been concerned with molecular archaeological studies aimed at revealing the origins and evolutionary histories of permeases (1). These studies have revealed that several different families, defined on the basis of sequence similarities, arose independently of each other, at different times in evolutionary history, following different routes. When complete microbial genomes first became available for analysis, we adapted p- existing software and designed new programs that allowed us quickly to identify probable transmembrane proteins, estimate their topologies and determine the likelihood that they function in transport (2). This work allowed us to expand previously-recognized families and to identify dozens of new families. All of this work then led us to attempt to design a rational but comprehensive classification system that would be applicable to the complete complement of transport systems found in all living organisms (3). The classification system that we have devised is based primarily on mode of transport and energy coupling mechanism, secondarily on molecular phylogeny, and lastly on the substrate specificities of the individual permeases (4).

Systems Metabolic Engineering is changing the way microbial cell factories are designed and optimized for industrial production. Integrating systems biology and biotechnology with new concepts from synthetic biology enables the global analysis and engineering of microorganisms and bioprocesses at super efficiency and versatility otherwise not accessible. Without doubt, systems metabolic engineering is a major driver towards bio-based production of chemicals, materials and fuels from renewables and thus one of the core technologies of global green growth. In this book, Christoph Wittmann and Sang-Yup Lee have assembled the world leaders on systems metabolic engineering and cover the full story - from genomes and networks via discovery and design to industrial implementation practises. This book is a comprehensive resource for students and researchers from academia and industry interested in systems metabolic engineering. It provides us with the fundaments to targeted engineering of microbial cells for sustainable bio-production and stimulates those who are interested to enter this exiting research field.

Coxiella burnetii is the etiological agent of Q fever, a zoonotic disease found worldwide. The bacterium is a fascinating example of intracellular parasitism that has uniquely evolved to thrive in the most inhospitable of cellular compartments-the phagolysosome. Understanding how C. burnetii resists the degradative functions of this vacuole, and the host cell functions coopted for successful parasitism, are central to understanding Q fever pathogenesis. Recent achievements in glycomics and proteomics are guiding development of enhanced detection schemes for the bacterium in addition to shedding light on the host immune response to the pathogen. Several chapters survey immune functions that control or potentially exacerbate Coxiella infection and delve into correlates of protective immunity elicited by vaccination. Comparative genomics is also the foundation of chapters discussing diagnostic antigen discovery and molecular typing of the bacterium, with significance for development of new clinical, epidemiologic, and forensic tools.

J. Warren Evans Department of Animal Science Texas A&M University College Station, Texas 77843 In the near future, improvement of domestic animals for the production of food and fiber is poised to undergo a revolution by the utilization of recent breakthroughs and advances in molecular genetics, embryo manipula tions, and gene transfer systems. Utilization of these techniques will have a wide impact on animal agriculture by improvement of production effi ciency via manipulation and control of many physiological systems. The end result will be to decrease production costs, increase food production and quality, and lower food costs. Health and well being of domestic and other animals will be improved as a result of new methods of disease diagnosis, vaccine production, and disease prevention practices. Genetic engineering also offers the possibility of utilizing animals for the development of pharmaceutical products to benefit society. Research progress will be en hanced via manipulation of the gene pool. The objectives of this Conference were to discuss the current status of animal bioengineering and to realistically assess the potential applica tions of current and future genetic technologies for the production of food and fiber to meet the needs of our hungry world, and to provide animal sci entists who may wish to utilize bioengineering in current or future re search programs with current background information regarding concepts, ap plications, and methodologies."
