Throughout history, human life has been seriously threatened by bacterial infectious diseases. After the discovery of antibiotics, humanity thought it had won the fight against infectious bacteria. However, considering the rapid evolution of bacterial multidrug resistance and exhausted pipeline of antibiotics for fighting bacterial infectious diseases, we are approaching the ‘post-antibiotic’ era. Unlike eukaryote, bacteria are proficient in exchanging their genetic materials with others by means of horizontal gene transfer (HGT). As a vehicle for antibiotic resistance gene (ARG), plasmid is self-replicable and transferable in a wide range of host bacteria. Moreover, ways of HGT-mediated ARGs spreading are highly diverse among different species, implicating complex evolution routes for the development of multidrug resistance in bacteria. In recent years, multidrug resistance plasmids have been widely found in bacteria not only from clinical patients, but also from animals, birds and plants, as well as from natural environmental settings including soil and water – heralding that the ‘post-antibiotic’ era is much closer than we previously thought. The global crisis of multidrug resistance calls for a closer collaboration among people of different professions in different regions, countries and continents, which will help us recognize the current situation and eventually find effective and long-lasting solutions for fighting against infectious bacteria.

Horizontal gene transfer (HGT) events encompass processes as varied as the exchange of genetic material between microbes coexisting in the same environment, between symbiotic bacteria and their eukaryotic hosts, and the evolution of organelles by symbiosis, in which whole genomes are acquired. In Horizontal Gene Transfer: Genomes in Flux, expert researchers contribute an overview of HGT concepts as well as specific case histories that highlight the most current progress to inspire future work. Divided into three sections, the volume begins with an overview of terminology, concepts and the implications of HGT on current evolutionary thought and philosophy, and continues with methods involving computer and bioinformatics analyses of genomic data as well as molecular biology techniques for identifying, quantifying, and differentiating instances of HGT. A section of case studies follows, which provides detailed accounts of how HGT has shaped evolution across the diversity of organisms and organismal lineages. As a volume of the highly successful Methods in Molecular BiologyTM series, this work provides the kind of detailed description and implementation advice that is crucial for getting optimal results. Cutting-edge and thoroughly detailed, Horizontal Gene Transfer: Genomes in Flux examines how HGT has contributed to genome evolution and how understanding HGT impacts our ability to accurately reconstruct and comprehend the web-like evolutionary history in order to aid scientists in furthering their own research.

Horizontal Gene Transfer

Horizontal Gene Transfer

The book focuses on the evolutionary impact of horizontal gene transfer processes on pathogenicity, environmental adaptation and biological speciation.

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.

Lateral Gene Transfer in Evolution

Lateral Gene Transfer in Evolution

This book represents the manyfold contributions of LGT to the evolution of micro and, to an extent, macroorganisms by focusing on the areas where it has the largest impact: metabolic innovations and adaptations and speciation.

Although the phenomenon of lateral gene transfer has been known since the 1940's, it was the genomics era that has really revealed the extent and many facets of this evolutionary/genetic phenomenon. Even in the early 2000s with but a handful of genomes available it became clear that the nature of microorganisms is full of genetic exchange between lineages that are sometimes far apart. The years following this saw an explosion of genomic data, which shook the "tree of life" and also raised doubts about the most appropriate species concepts for prokaryotes. This book attempts to represent the many-fold contributions of LGT to the evolution of micro and, to an extent, macro-organisms by focusing on the areas where the Editor felt it had the largest impact: metabolic innovations and adaptations and speciation.

The second edition of Horizontal Gene Transfer has been organized to provide a concise and up-to-date coverage of the most important discoveries in this fascinating field. Written by the most prominent gene transfer and genome analytical scientists, this book details experimental evidence for the phenomenon of horizontal gene transfer and discusses further evidence provided by the recent completion of genomic sequences from Archea, Bacteria, and Eucarya members. The relevance of horizontal gene transfer to plant and metazoan taxonomy, GM foods, antibiotic resistance, paleontology, and phylogenetic reconstruction is also explored. Horizontal Gene Transfer is essential for microbiologists, geneticists, biochemists, evolutionary biologists, infectious disease specialists, paleontologists, ecologists, and researchers working in plant/animal systematics and agriculture with an interest in gene transfer. This includes scientific researchers from government and industry concerned with the release of genetically modified organisms. Up-to-the-minute reviews, maps, conclusions, urls to relevant websites and colour figures Unique chapters, for example one written by paleontologists presents data for horizontal gene transfer from fingerprints form the fossil record

This book gives an overview of gene transfer and stability in those aquatic and terrestrial environments where bacteria and fungi can survive and interact genetically. It examines the role played by sex between microbes in the evolution of populations and their survival. Special emphasis is placed on methodology, including the analysis by novel techniques of genetic material extracted directly from soils, rivers and lakes. The natural spread of antibiotic resistance and the safe use of genetically manipulated microbes are matters of considerable scientific, medical and public concern upon which the investigations presented here have direct bearing. This unique collection will be of value to specialist researchers in applied microbiology, ecology and biotechnology as well as biomedical scientists interested in the environmental risks of genetic engineering.
