This book was released on 2007-01-01 with total page 203 pages. Available in PDF, EPUB and Kindle. Book excerpt: "Our way of understanding evolution has changed completely with the era of genomics, particularly since the emergence of comparative genomics, a discipline allowing the analysis of complete genomes and biological processes over vast periods of time. In this volume, internationally recognized experts present and discuss an update of the evolutionary processes at the onset of organismal diversification and complexity, and review the mechanisms leading to the acquisition of new traits and functions. Different levels of evolution are considered, from internal modules in genes and proteins to interactomes and biological networks, with integration of the influence of both the genomic environment and the ecological context. Particular emphasis will be given to the origin of novel genes and gene functions as well as to the evolutionary impact of the duplication of genetic information, with several chapters devoted to transposable elements. Providing an excellent update on gene and protein evolution, this book will be appreciated by researchers in biology and medicine, biology teachers and anyone interested in evolution and genomics."--Publisher's description.

Download or read book Sequence Evolution Function written by Eugene V. Koonin and published by Springer Science & Business Media. This book was released on 2013-06-29 with total page 482 pages. Available in PDF, EPUB and Kindle. Book excerpt: Sequence - Evolution - Function is an introduction to the computational approaches that play a critical role in the emerging new branch of biology known as functional genomics. The book provides the reader with an understanding of the principles and approaches of functional genomics and of the potential and limitations of computational and experimental approaches to genome analysis. Sequence - Evolution - Function should help bridge the "digital divide" between biologists and computer scientists, allowing biologists to better grasp the peculiarities of the emerging field of Genome Biology and to learn how to benefit from the enormous amount of sequence data available in the public databases. The book is non-technical with respect to the computer methods for genome analysis and discusses these methods from the user's viewpoint, without addressing mathematical and algorithmic details. Prior practical familiarity with the basic methods for sequence analysis is a major advantage, but a reader without such experience will be able to use the book as an introduction to these methods. This book is perfect for introductory level courses in computational methods for comparative and functional genomics.

Available in PDF, EPUB and Kindle. Book excerpt: Evolving Genes and Proteins covers the proceedings of the "Evolving Genes and Proteins" symposium, held at the Institute of Microbiology of Rutgers, The State University on September 17 and 18, 1964, with support from the National Science Foundation. The book focuses on the structural and functional features of proteins and nucleic acids. The selection first offers information on lysine biosynthesis and evolution, lipid patterns in the evolution of organisms, and evolution of heme and chlorophyll. Discussions focus on the evolution of the genes of the porphyrin biosynthetic chain, polyunsaturated fatty acids in plants and animals, and diagnostic radiocarbon tracers. The text then examines evolutionary divergence and convergence in proteins; evolution of hemoglobin in primates; and constancy and variability of protein structure in respiratory and viral proteins. The publication takes a look at the comparative aspects of the structure and function of phosphoglucomutase, evolution of dehydrogenases, and enzymatic homology and analogy in phylogeny. The text also ponders on the evolution of an enzyme, role of mutations in evolution, enzyme catalysis and color of light in bioluminescent reactions, and evolution of the lactose utilization gene system in enteric bacteria. The selection is a valuable reference for microbiologists and readers interested in the study of genes and proteins.

Download or read book Protein Evolution by Exon Shuffling written by Laszlo Patthy and published by Springer. This book was released on 1995-07-06 with total page 158 pages. Available in PDF, EPUB and Kindle. Book excerpt: The book surveys current evidence for modular protein evolution by exon-shuffling and lists the proteins that clearly evolved by this mechanism. Analysis of the evolutionary history of these proteins is used to illustrate the principles and mechanism of this process. The book also discusses the evolutionary history and significance of exon-shuffling. There has been much controversy as to the role of this evolutionary mechanism in protein evolution. This volume attempts to eliminate some of the misunderstandings that are still quite general in this field by indicating the source of some of the conceptual errors.

Download or read book Examining the Processes of Protein Evolution in a Lineage Specific Context in Genomes written by Russell A. Hermansen and published by . This book was released on 2017 with total page 536 pages. Available in PDF, EPUB and Kindle. Book excerpt: Understanding how genotypic changes impact the phenotype of an organism is a primary goal in molecular evolution. A primary means to discovering genes that have important phenotypic activities is to locate genes that have evolved under positive selection, through which protein function has changed. By placing duplication events and instances of accelerated rates of evolution, measured through the normalized rate of nonsynonymous to synonymous substitutions (dN/dS), in the context of the underlying species tree it becomes possible to determine in a lineage-specific manner changes on individual lineages that impact phenotype. Understanding how positively selected genes have evolved differently from closely related homologs makes it possible to make inference into the genomic changes that have contributed to species diversification. The process of examining evolution in a lineage-specific manner is performed herein through several different examples from the level of specific gene families to genome scale analyses. Furthermore, presented here is a new version of The Adaptive Evolution Database (TAED), which is a comparative genetic resource of phylogenetically-indexed gene families to detect instances of positive directional and diversifying selection within chordate genomes. Phylogenetic inquiries into the lineage-specific evolution of termites, salmon, and the cereal crop Tef are investigated here. It was demonstrated that multiple instances of positive selection on specific genes and large and small scale duplications have impacted the evolution of each species differently. Specific instances of gene family evolution are investigated including the de novo pyrimidine biosynthesis pathway of yeast, myostatin in teleost fish, and the glycolysis pathway across various domains of life to both determine the selective pressures exerted on these pathways and the interplay between mutation and selection. Inquires into the evolution of chordate species are made using TAED and evolutionary trends within the phylum are examined. Here it is concluded that both positive selection and gene duplication play an important role in the evolution of species. Current methods for detecting selection based upon dN/dS are limited and methodology using pathway flux analyses is explored. It is demonstrated that even within highly conserved pathways across the tree of life that duplication and positive directional selection play an important role in alleviating the constraints of negative selection and allow for rapid sequence evolution. Gene retention after whole genome duplication (WGD) is explored in the Atlantic salmon genome which has undergone four rounds of WGD. The retention of gene duplicates in Atlantic salmon gives small support to the “Gene Duplicability Hypothesis” but demonstrated there is little interaction in retention probabilities between different rounds of WGD. Examination of the termite genome yielded insight into the evolution of eusociality within a primitively eusocial insect and demonstrated that strong selection and gene family expansions on genes relating to male fertility may influence termite evolution. Hypotheses into the abiotic and stress response pathways of Tef are generated through a lineage-specific examination of the proteins under selection on the Tef lineage. This work concludes by highlighting the need to perform examinations of genomic ancestry in a lineage-specific manner to determine how natural selection and random mutation have caused species divergence.
Download or read book Evolution by Gene Duplication written by Susumu Ohno and published by Springer Science & Business Media. This book was released on 2013-12-11 with total page 171 pages. Available in PDF, EPUB and Kindle. Book excerpt: It is said that "necessity is the mother of invention". To be sure, wheels and pulleys were invented out of necessity by the tenacious minds of upright citi zens. Looking at the history of mankind, however, one has to add that "Ieisure is the mother of cultural improvement". Man's creative genius flourished only when his mind, freed from the worry of daily toils, was permitted to entertain apparently useless thoughts. In the same manner, one might say with regard to evolution that "natural selection mere(y tnodifted, while redundanry created". Natural selection has been extremely effective in policing alleHe mutations which arise in already existing gene loci. Because of natural selection, organisms have been able to adapt to changing environments, and by adaptive radiation many new species were created from a common ancestral form. Y et, being an effective policeman, natural selection is extremely conservative by nature. Had evolution been entirely dependent upon natural selection, from a bacterium only numerous forms of bacteria would have emerged. The creation of metazoans, vertebrates and finally mammals from unicellular organisms would have been quite impos sible, for such big leaps in evolution required the creation of new gene loci with previously nonexistent functions. Only the cistron which became redun dant was able to escape from the relentless pressure of natural selection, and by escaping, it accumulated formerly forbidden mutations to emerge as a new gene locus.
