Download or read book Incompatibility in Fungi written by Karl Esser and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 131 pages. Available in PDF, EPUB and Kindle. Book excerpt: Sexual reproduction in the fungi is extensively regulated by incom patibility, which determines, in the absence of any morphological differ entiation, the pattern of mating among individual strains. Control of the interactions that comprise the sexual reproductive process resides in specific genetic factors, the incompatibility factors, which occur in several distinct systems in the various groups of fungi and which exert their control in two basically different ways. On the one hand, the system may play the same role as dioecy in higher organisms by restricting or preventing inbreeding among the members of the same race (homo genic incompatibility) and thus enhance outbreeding. On the other hand, the system may impose the opposite effect by restricting or preventing interbreeding between members of different races (heterogenic incompatibility) and thus promote inbreeding. In addition to these basic facts concerning the general biological signi ficance of incompatibility, important advances have been made in recent years, especially in the investigation of the genetics of incompatibility systems. Sufficient information concerning the genetic determination of incompatibility is now available to understand many phenomena which were very mysterious in the 1920's, when H. KNIEP, of Wiirzburg, Ger many, laid the groundwork for all subsequent study of incompatibility in the higher fungi. Furthermore, there is at present enough conceptual understanding of the physiological activity of the incompatibility-genes and of their action in morphogenetic processes to permit at least the formulation of plausible models of the operation of incompatibility systems.

Download or read book Rapidly Evolving Genes and Genetic Systems written by Rama S. Singh and published by OUP Oxford. This book was released on 2012-06-28 with total page 312 pages. Available in PDF, EPUB and Kindle. Book excerpt: Ever since the pioneering work of Darwin and Wallace, evolutionary biologists have attempted to understand the evolutionary dynamics of genetic systems. A range of theories on evolutionary ratesfrom static to gradual to punctuated to quantumhave been developed, primarily by comparing morphological changes over geological timescales as described in the fossil record. Recent studies, however, are beginning to change the way that we view evolutionary patterns and processes. New paleontological, experimental, molecular, and genomic investigations are providing a tremendous amount of novel data and fresh perspectives, offering valuable insights on the rates of evolutionary change, particularly in fast-evolving genetic systems. Rapidly Evolving Genes and Genetic Systems captures these recent exciting developments across a broad range of morphological, molecular, cellular, developmental, and genetic investigations in both natural and experimental populations over a diversity of life forms. The book provides a fascinating series of case studies that exemplify rapid evolution, and showcases the diversity of rapidly evolving genes and genetic systems, emphasizing the extremely important roles that they play in adaptation, speciation, and the generation and maintenance of a diversity of biological traits and properties. This exciting collection showcases the latest research of more than 50 eminent evolutionary biologists. It will be suitable for senior undergraduate students, graduate students, researchers, and for all those interested in the study of evolution.
Download or read book Translating by Factors written by Christoph Gutknecht and published by SUNY Press. This book was released on 1996-01-01 with total page 376 pages. Available in PDF, EPUB and Kindle. Book excerpt: By emphasizing, using English-German examples, the notion of factor set, this book fosters the awareness that successful and adequate translation requires properly accounting for the pertinent translation factors in each individual case. The factor approach gives translation criticism an objective yardstick for assessing the quality of translations . The authors explore the linguistic factors, including treatment of illocution and its indeterminacy, and perlocution, as well as non-linguistic factors such as factuality, situation, and culture. The book also includes aspects more genuinely linked to the notion of translation itself, such as translation units and word class and the nature and status of factors in translation theory.
Download or read book Dengue and Zika Control and Antiviral Treatment Strategies written by Rolf Hilgenfeld and published by Springer. This book was released on 2018-05-29 with total page 375 pages. Available in PDF, EPUB and Kindle. Book excerpt: This contributed volume contains 25 chapters from leading international scientists working on dengue and Zika viruses, who came together in Praia do Tofo in Mozambique to discuss the latest developments in the fields of epidemiology, pathogenesis, structural virology, immunology, antiviral drug discovery and development, vaccine efficacy, and mosquito control programs. The meeting venue offered an opportunity to discuss current research on these flaviviruses in an idyllic setting, and also to develop first-hand appreciation of the issues in infectious diseases facing developing countries and of the research gaps in Africa. For readers, who should include basic and clinical researchers in the field and public health professionals, the chapters are organized to provide a comprehensive overview of the various topics in current dengue and Zika virus research. A unique feature of the proceedings of this meeting is the inclusion of the discussions that took place following presentations. These have been transcribed and appended to the end of the relevant chapters, and they form the “salt in the soup” of this book.
Download or read book Self Incompatibility in Flowering Plants written by Vernonica E. Franklin-Tong and published by Springer Science & Business Media. This book was released on 2008-07-30 with total page 341 pages. Available in PDF, EPUB and Kindle. Book excerpt: Great progress has been made in our understanding of pollen-pistil interactions and self-incompatibility (SI) in flowering plants in the last few decades. This book covers a broad spectrum of research into SI, with accounts by internationally renowned scientists. It comprises two sections: Evolution and Population Genetics of SI, Molecular and Cell Biology of SI Systems. The reader will gain an insight into the diversity and complexity of these polymorphic cell-cell recognition and rejection systems. Heteromorphic and homomorphic SI systems and our current understanding of the evolution and phylogeny of these systems, based on the most recent molecular sequence data, are covered. Further, the book presents major advances in our knowledge of the pistil and pollen S-determinants and other unlinked components involved in SI, as well as the apparently diverse cellular regulatory mechanisms utilised to ensure inhibition of “self” pollen.
Download or read book Genetics of Fungi written by Karl Esser and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 509 pages. Available in PDF, EPUB and Kindle. Book excerpt: The significance of genetics in biology today stems to a considerable extent from the knowledge which has been obtained through the use of fungi as experimental objects. As a result of their short generation time, their ease of culture under laboratory conditions, and the possibil ity of identifying the four products of meiosis through tetrad analysis, the fungi have proven themselves in many ways superior to the classic genetic experimental material such as Drosophila and maize. Because they permit investigation of genetic fine structure as well as biochemical analysis of the function of the genetic material, the fungi can be used, just as the bacteria and bacteriophages, for molecular biological research. Further, the fungi, because of their simple organi zation, are suitable for investigation of the genetic and physiological bases of morphogenesis and of extrachromosomal inheritance. This monograph is an attempt to summarize and interpret the results of genetic research on fungi. The reader should be reminded that review and interpretation of original research are inevitably influenced by the authors' own opinions. An understanding of the basic principles of genetics is assumed.
Download or read book Handbook of Genetics written by Robert C. King and published by Springer Science & Business Media. This book was released on 2013-11-11 with total page 668 pages. Available in PDF, EPUB and Kindle. Book excerpt: The purpose of this and future volumes of the Handbook of Genetics is to bring together a collection of relatively short, authoritative essays or annotated compilations of data on topics of significance to geneticists. Many of the essays will deal with various aspects of the biology of certain species selected because they are favorite subjects for genetic investigation in nature or the laboratory. Often there will be an encyclopedic amount of information available on such a species, with new papers appearing daily. Most of these will be written for specialists in a jargon that is be wildering to a novice, and sometimes even to a veteran geneticist working with evolutionarily distant organisms. For such readers what is needed is a written introduction to the morphology, life cycle, reproductive be havior, and culture methods for the species in question. What are its par ticular advantages (and disadvantages) for genetic study, and what have we learned from it? Where are the classic papers, the key bibliographies, and how does one get stocks of wild type or mutant strains? The chapters devoted to different species will contain information of this sort. Only a few hundreds of the millions of species available to biologists have been subjected to detailed genetic study. However, those that have make up a very heterogeneous sample of the living world.
Download or read book Vehicle Compatibility in Automotive Crashes written by Stanley H Backaitis and published by SAE International. This book was released on 2005-03-29 with total page 519 pages. Available in PDF, EPUB and Kindle. Book excerpt: For years, reducing the number of traffic-related fatalities and injuries has been a major problem throughout the world. Today, it has gained much more momentum in view of rapidly increasing SUV, van, and light-truck populations relative to the number of passenger cars, and due to significant improvements in technologies that facilitate a better understanding of the interaction dynamics among widely differing size vehicles. Unless disparities in crashworthiness among vehicles of different masses, sizes, and structural characteristics in mixed crash environments are successfully taken into account, the challenge toward improved vehicle safety will continue. This two-part compendium provides the most comprehensive information available on the entire spectrum of vehicle crash compatibility. The first part presents oral comments captured from the 2003 SAE World Congress panel discussion on compatibility. The panel of leading experts representing industry, academia, and government provides a rough framework and a broad range of views on current and emerging developments in compatibility research. The second part of this compendium features 44 best technical papers from SAE International and the International Technical Conference on the Enhanced Safety of Vehicles, published from the early 1970s through 2004. Readers will get a feel for the direction passenger car and heavy-vehicle manufacturers, research institutions, infrastructure suppliers, insurers, and governments are taking to reduce the number of traffic fatalities and injuries.
