Download or read book Inferring Phylogenies written by Joseph Felsenstein and published by Sinauer Associates Incorporated. This book was released on 2004-01 with total page 664 pages. Available in PDF, EPUB and Kindle. Book excerpt: Phylogenies, or evolutionary trees, are the basic structures necessary to think about and analyze differences between species. Statistical, computational, and algorithmic work in this field has been ongoing for four decades now, and there have been great advances in understanding. Yet no book has summarized this work. Inferring Phylogenies does just that in a single, compact volume. Phylogenies are inferred with various kinds of data. This book concentrates on some of the central ones: discretely coded characters, molecular sequences, gene frequencies, and quantitative traits. Also covered are restriction sites, RAPDs, and microsatellites.

Download or read book The Pangenome written by Hervé Tettelin and published by Springer Nature. This book was released on 2020-04-30 with total page 311 pages. Available in PDF, EPUB and Kindle. Book excerpt: This open access book offers the first comprehensive account of the pan-genome concept and its manifold implications. The realization that the genetic repertoire of a biological species always encompasses more than the genome of each individual is one of the earliest examples of big data in biology that opened biology to the unbounded. The study of genetic variation observed within a species challenges existing views and has profound consequences for our understanding of the fundamental mechanisms underpinning bacterial biology and evolution. The underlying rationale extends well beyond the initial prokaryotic focus to all kingdoms of life and evolves into similar concepts for metagenomes, phenomes and epigenomes. The book’s respective chapters address a range of topics, from the serendipitous emergence of the pan-genome concept and its impacts on the fields of microbiology, vaccinology and antimicrobial resistance, to the study of microbial communities, bioinformatic applications and mathematical models that tie in with complex systems and economic theory. Given its scope, the book will appeal to a broad readership interested in population dynamics, evolutionary biology and genomics.
Download or read book Cell Cell Channels written by František Baluška and published by Springer Science & Business Media. This book was released on 2006-08-28 with total page 331 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book covers cell-cell channels at all levels of biological organization. The purpose of this book is to document that cells are not physically separated and fully autonomous units of biological life as stated by the currently valid Cell Theory. If not the cell then some lower level unit must fulfill this role. The book deals also with the identity of this elusive unit of biological life.
Download or read book Pathogenicity Islands and the Evolution of Pathogenic Microbes written by J. Hacker and published by Springer Science & Business Media. This book was released on 2002-03-12 with total page 240 pages. Available in PDF, EPUB and Kindle. Book excerpt: It has been known for a number of years that not only pathogenicity islands but also plasmids and bacteriophages are able to carry genes whose products are involved in pathogenic processes. Accordingly, such elements and their products play an important role in pathogenesis due to the intestinal E. coli as well to Shigellae. Another interesting aspect which is reflected in different articles is that genomes evolve by acquisition of new pieces of DNA following gene transfer, but also by genome reduction. Different mechanisms include the deletion of sequences or the elimination of functions by the accumulation of point mutations or rearrangements.
Download or read book Horizontal Gene Transfer written by Tomás G. Villa and published by Springer. This book was released on 2019-08-13 with total page 425 pages. Available in PDF, EPUB and Kindle. Book excerpt: 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.
Download or read book Lateral DNA Transfer written by Frederic Bushman and published by CSHL Press. This book was released on 2002 with total page 472 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book is about mobile genes—the transfer of DNA between unrelated cells. It discusses the machinery of gene transfer and its wide-ranging biological and health consequences. Mobile DNA makes possible the development of antibiotic resistance in microbes, the conversion of harmless to pathogenic bacteria, and the triggering of cancerous growth in cells. It also contributes to human evolution. This well-illustrated volume contains an up-to-date account of a topic now seen as increasingly important, and will be invaluable for both working scientists and as a textbook for advanced courses.

Download or read book Structure and Function of the Bacterial Genome written by Charles J. Dorman and published by John Wiley & Sons. This book was released on 2020-04-28 with total page 437 pages. Available in PDF, EPUB and Kindle. Book excerpt: Presents an integrated view of the expression of bacterial genetic information, genome architecture and function, and bacterial physiology and pathogenesis This book blends information from the very latest research on bacterial chromosome and nucleoid architecture, whole-genome analysis, cell signaling, and gene expression control with well-known gene regulation paradigms from model organisms (including pathogens) to give readers a picture of how information flows from the environment to the gene, modulating its expression and influencing the competitive fitness of the microbe. Structure and Function of the Bacterial Genome explores the governance of the expression of the genes that make a bacterium what it is, and updates the basics of gene expression control with information about transcription promoter structure and function, the role of DNA as a regulatory factor (in addition to its role as a carrier of genetic information), small RNAs, RNAs that sense chemical signals, ribosomes and translation, posttranslational modification of proteins, and protein secretion. It looks at the forces driving the conservation and the evolution of the dynamic genome and offers chapters that cover DNA replication, DNA repair, plasmid biology, recombination, transposition, the roles of repetitive DNA sequences, horizontal gene transfer, the defense of the genome by CRISPR-Cas, restriction enzymes, Argonaute proteins and BREX systems. The book finishes with a chapter that gives an integrated overview of genome structure and function. Blends knowledge of gene regulatory mechanisms with a consideration of nucleoid structure and dynamics Offers a 'DNA-centric' approach to considering transcription control Views horizontal gene transfer from a gene regulation perspective Assesses the opportunities and limitations of designing synthetic microbes or rewiring existing ones Structure and Function of the Bacterial Genome is an ideal book for graduate and undergraduate students studying microbial cell biology, bacterial pathogenesis, gene regulation, and molecular microbiology. It will also appeal to principal investigators conducting research on these and related topics and researchers in synthetic biology and other arms of biotechnology.

Available in PDF, EPUB and Kindle. Book excerpt: A unique and timely review of the emergence of eukaryotic virulence in fungi, oomycetes, and protozoa, as they affect both animals and plants Evolution of Virulence in Eukaryotic Microbes addresses new developments in defining the molecular basis of virulence in eukaryotic pathogens. By examining how pathogenic determinants have evolved in concert with their hosts, often overcoming innate and adaptive immune mechanisms, the book takes a fresh look at the selective processes that have shaped their evolution. Introductory chapters ground the reader in principal evolutionary themes such as phylogenetics and genetic exchange, building a basis of knowledge for later chapters covering advances in genetic tools, how pathogens exchange genetic material in nature, and the common themes of evolutionary adaptation that lead to disease in different hosts. With the goal of linking the research findings of the many disparate scientific communities in the field, the book: Assembles for the first time a collection of chapters on the diversity of eukaryotic microorganisms and the influence of evolutionary forces on the origins and emergence of their virulent attributes Highlights examples from three important, divergent groups of eukaryotic microorganisms that cause disease in animals and plants: oomycetes, protozoan parasites, and fungi Covers how the development of genetic tools has fostered the identification and functional analyses of virulence determinants Addresses how pathogens exchange genetic material in nature via classical or modified meiotic processes, horizontal gene transfer, and sexual cycles including those that are cryptic or even unisexual Provides a broad framework for formulating future studies by illustrating themes common to different pathogenic microbes Evolution of Virulence in Eukaryotic Microbes is an ideal book for microbiologists, evolutionary biologists and medical professionals, as well as graduate students, postdoctoral fellows, and faculty members working on the evolution of pathogens.
Download or read book Agrobacterium From Biology to Biotechnology written by Tzvi Tzfira and published by Springer Science & Business Media. This book was released on 2007-12-25 with total page 768 pages. Available in PDF, EPUB and Kindle. Book excerpt: Agrobacterium is a plant pathogen which causes the “crown-gall” disease, a neoplastic growth that results from the transfer of a well-defined DNA segment (“transferred DNA”, or “T-DNA”) from the bacterial Ti (tumor-inducing) plasmid to the host cell, its integration into the host genome, and the expression of oncogenes contained on the T-DNA. The molecular machinery, needed for T-DNA generation and transport into the host cell and encoded by a series of chromosomal (chv) and Ti-plasmid virulence (vir) genes, has been the subject of numerous studies over the past several decades. Today, Agrobacterium is the tool of choice for plant genetic engineering with an ever expanding host range that includes many commercially important crops, flowers, and tree species. Furthermore, its recent application for the genetic transformation of non-plant species, from yeast to cultivated mushrooms and even to human cells, promises this bacterium a unique place in the future of biotechnological applications. The book is a comprehensive volume describing Agrobacterium's biology, interactions with host species, and uses for genetic engineering.
