Available in PDF, EPUB and Kindle. Book excerpt: Cytoplasmic Genes and Organelles is about cytoplasmic genes: what they are and what they do. It applies the concepts and methods of cytoplasmic genetics to the problems of cell and molecular biology to which they can uniquely contribute. It shows geneticists the many attractive problems in this area awaiting their attention; cell biologists and biochemists the usefulness of cytoplasmic genetic analysis in their endeavors; and students the potential power of an integrated experimental approach using cytoplasmic genes together with the more conventional tools of biochemistry and electron microscopy in the investigation of organelle biogenesis. The book treats the following aspects of cytoplasmic genetic systems: (1) the properties of cytoplasmic DNA; (2) the genetic analysis of cytoplasmic systems; and (3) the functions of cytoplasmic genes in organelle biogenesis. The opening chapter summarizes the principal findings to provide readers with a bird's eye view of the subject. Subsequent chapters cover topics such as cytoplastmic DNAs; cytoplasmic genes in Chlamydomonas; mitochondrial genetics of yeast; cytoplasmic genes in higher plants; the role of mitochondrial genes in mitochondrial biogenesis; and cytoplasmic genes and cell heredity.

Available in PDF, EPUB and Kindle. Book excerpt: The compartmentation of genetic information is a fundamental feature of the eukaryotic cell. The metabolic capacity of a eukaryotic (plant) cell and the steps leading to it are overwhelmingly an endeavour of a joint genetic cooperation between nucleus/cytosol, plastids, and mitochondria. Alter ation of the genetic material in anyone of these compartments or exchange of organelles between species can seriously affect harmoniously balanced growth of an organism. Although the biological significance of this genetic design has been vividly evident since the discovery of non-Mendelian inheritance by Baur and Correns at the beginning of this century, and became indisputable in principle after Renner's work on interspecific nuclear/plastid hybrids (summarized in his classical article in 1934), studies on the genetics of organelles have long suffered from the lack of respectabil ity. Non-Mendelian inheritance was considered a research sideline~ifnot a freak~by most geneticists, which becomes evident when one consults common textbooks. For instance, these have usually impeccable accounts of photosynthetic and respiratory energy conversion in chloroplasts and mitochondria, of metabolism and global circulation of the biological key elements C, N, and S, as well as of the organization, maintenance, and function of nuclear genetic information. In contrast, the heredity and molecular biology of organelles are generally treated as an adjunct, and neither goes as far as to describe the impact of the integrated genetic system.

This book was released on 2004 with total page 671 pages. Available in PDF, EPUB and Kindle. Book excerpt: Plant organelles have intrigued biologists since the discovery of their endosymbiontic origin and maternal inheritance. The first application of organelle biotechnology was the role of cytoplasmic male sterility in hybrid seed production and "Green Revolution". In modern times, plant organelles are again leading the way for the creation of genetically modified crops. On a global scale, 75% of GM crops are engineered for herbicide resistance and most of these herbicides target pathways that reside within plastids. Several thousand proteins are imported into chloroplasts that participate in biosynthesis of fatty acids, amino acids, pigments, nucleotides and numerous metabolic pathways including photosynthesis. Thus, from green revolution to golden rice, plant organelles have played a critical role in revolutionizing agriculture. This book details not only basic concepts and current understanding of plant organelle genetics and molecular biology but also focuses on the synergy between basic biology and biotechnology. Forty four authors from nine countries have contributed twenty four chapters containing many figures and tables. Section 1 on organelle genomes and proteomes discusses molecular features of plastid and mitochondrial genomes, evolutinary origins, somatic and sexual inheritance, proteomics, bioinformatics and functional genomics. Section 2 on organelle gene expression and signalling discusses transcription, translation, RNA processing/editing, introns and splicing, protein synthesis, proteolysis, import of proteins into chloroplast and mitochondria and their regulation. Section 3 on organelle biotechnology discusses chloroplast and nuclear genetic engineering for biotic/abiotic stress tolerance, improved fatty acid/amino acid biosynthesis, biopharmaceuticals, biopolymers and biomaterials, cytoplasmic male sterility for hybrid seed production, plant improvement and restoration of fertility. This book is designed to serve as a comprehensive volume and reference guide for teachers, advanced undergraduates and graduate students and researchers in plant molecular biology and biotechnology.
Download or read book Organelle Genetics written by Charles E. Bullerwell and published by Springer Science & Business Media. This book was released on 2011-10-26 with total page 481 pages. Available in PDF, EPUB and Kindle. Book excerpt: Mitochondria and chloroplasts are eukaryotic organelles that evolved from bacterial ancestors and harbor their own genomes. The gene products of these genomes work in concert with those of the nuclear genome to ensure proper organelle metabolism and biogenesis. This book explores the forces that have shaped the evolution of organelle genomes and the expression of the genes encoded by them. Some striking examples of trends in organelle evolution explored here are the reduction in genome size and gene coding content observed in most lineages, the complete loss of organelle DNA in certain lineages, and the unusual modes of gene expression that have emerged, such as the extensive and essential mRNA editing that occurs in plant mitochondria and chloroplasts. This book places particular emphasis on the current techniques used to study the evolution of organelle genomes and gene expression.
Download or read book Formation and Fate of Cell Organelles written by Katherine Brehme Warren and published by Elsevier. This book was released on 2012-12-02 with total page 361 pages. Available in PDF, EPUB and Kindle. Book excerpt: Formation and Fate of Cell Organelles presents the proceedings of the symposia of the International Society for Cell Biology. Contributors offer their views on various aspects of the problem of spontaneous assembly, particularly how cellular structures arise from the component molecules. They consider whether all cellular organelles and cells, themselves, can arise by spontaneous assembly, or whether some regulation is involved and the mechanisms underlying such regulation. This book is organized into 16 chapters and begins with an overview of self-assembling systems of equal units and how they can be built efficiently, focusing on quasi-equivalence and helical waves on bacterial flagella. This text also discusses the differences in free energy of the molecules in their various states and the use of the free energy of a particular array of molecules to predict what arrays will form. The reader is introduced to intermolecular forces and how macromolecular lipid structures assemble in vitro, along with developments in the resolution of the spindle fibers of the mitotic apparatus. The book also looks into the mechanisms underlying the disposition of microtubules in plant cells during interphase and mitosis, and then concludes with a chapter on some studies dealing with cytoplasmic genes and cytoplasmic inheritance. This book is a valuable source of information for scientists and researchers engaged in fields ranging from cytology and biology to chemistry, pathology, and biophysics.

Download or read book Organelle Genes and Genomes written by Nicholas W. Gillham and published by Oxford University Press, USA. This book was released on 1994 with total page 424 pages. Available in PDF, EPUB and Kindle. Book excerpt: Chloroplasts and mitochondria contain their own genomes and protein-synthesizing systems, but only a fraction of the genes required for the proper function of these organelles are specified by the genomes. Organelle Genes and Genomes reviews the properties of chloroplast and mitochondrial geneomes and shows how such study is now contributing broadly to the resolution of important biological problems. These range from the use of organelle DNA molecules in evolutionary and phylogenetic studies to molecular investigations of the mechanisms underlying RNA editing, intron splicing and mobility, and mitochnodrial disease. The book is divided into four parts. Part I describes the structure and function of chloroplasts and mitochondria. Part II discusses their origins as well of the structure, content, and replication of their genomes for phylogenetic studies. Part III considers the genetics of model systems, transformation, the inheritance of organelle genomes and their intracellular genetics. This section includes chapters dealing with intron splicing, mobile elements, organelle plasmids and mitochondrial diseases. Part IV considers gene expression in organelles including novel problems like RNA editing. Students and researchers in genetics, molecular biology, cell biology, and evolution will welcome this new contribution by an eminent researcher in the field.

Download or read book Concepts of Biology written by Samantha Fowler and published by . This book was released on 2018-01-07 with total page 618 pages. Available in PDF, EPUB and Kindle. Book excerpt: Concepts of Biology is designed for the single-semester introduction to biology course for non-science majors, which for many students is their only college-level science course. As such, this course represents an important opportunity for students to develop the necessary knowledge, tools, and skills to make informed decisions as they continue with their lives. Rather than being mired down with facts and vocabulary, the typical non-science major student needs information presented in a way that is easy to read and understand. Even more importantly, the content should be meaningful. Students do much better when they understand why biology is relevant to their everyday lives. For these reasons, Concepts of Biology is grounded on an evolutionary basis and includes exciting features that highlight careers in the biological sciences and everyday applications of the concepts at hand.We also strive to show the interconnectedness of topics within this extremely broad discipline. In order to meet the needs of today's instructors and students, we maintain the overall organization and coverage found in most syllabi for this course. A strength of Concepts of Biology is that instructors can customize the book, adapting it to the approach that works best in their classroom. Concepts of Biology also includes an innovative art program that incorporates critical thinking and clicker questions to help students understand--and apply--key concepts.
Download or read book Compendium of Histology written by Anders Rehfeld and published by Springer. This book was released on 2017-09-07 with total page 670 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book has been designed to help medical students succeed with their histology classes, while using less time on studying the curriculum. The book can both be used on its own or as a supplement to the classical full-curriculum textbooks normally used by the students for their histology classes. Covering the same curriculum as the classical textbooks, from basic tissue histology to the histology of specific organs, this book is formatted and organized in a much simpler and intuitive way. Almost all text is formatted in bullets or put into structured tables. This makes it quick and easy to digest, helping the student get a good overview of the curriculum. It is easy to locate specific information in the text, such as the size of cellular structures etc. Additionally, each chapter includes simplified illustrations of various histological features. The aim of the book is to be used to quickly brush up on the curriculum, e.g. before a class or an exam. Additionally, the book includes guides to distinguish between the different histological tissues and organs that can be presented to students microscopically, e.g. during a histology spot test. This guide lists the specific characteristics of the different histological specimens and also describes how to distinguish a specimen from other similar specimens. For each histological specimen, a simplified drawing and a photomicrograph of the specimen, is presented to help the student recognize the important characteristics in the microscope. Lastly, the book contains multiple “memo boxes” in which parts of the curriculum are presented as easy-to-remember mnemonics.

Book excerpt: The scope and significance of cytoplasmic inheritance has been the subject of one of the longest controversies in the history of genetics. In the first major book on the history of this subject, Jan Sapp analyses the persistent attempts of investigators of non-Mendelian inheritance to establish their claims in the face of strong resistance from nucleo-centric geneticists and classical neo-Darwinians. A new perspective on the history of genetics is offered as he explores the conflicts which have shaped theoretical thinking about heredity and evolution throughout the century: materialism vs. vitalism, reductionism vs. holism, preformation vs. epigenesis, neo-Darwinism vs. new-Lamarckism, and gradualism vs. saltationism. In so doing, Sapp highlights competitive struggles for power among individuals and disciplinary groups. He accepts that political interests and general social contexts may directly affect scientific ideas, but develops the stronger thesis that social interests inside science itself are always involved in the content of scientific knowledge. He goes on to show that there are no neutral judges in scientific controversies and investigates the social strategies and methodological rhetoric used by scientists when they defend or oppose a particular theory. At the same time, Sapp illustrates the social constraints that ensure the high cost and risk of entertaining unorthodox theories in the sciences.

This book was released on 2013-11-11 with total page 354 pages. Available in PDF, EPUB and Kindle. Book excerpt: The first volume of the series, on "The Stability of the Differentiated State" received many favorable reviews from the scientific community. Many readers seem to agree with us that publication of topical volumes is a worthwhile alternative to periodic compilations of rather unrelated, though up-to-date reviews. Production of topical volumes is however, plagued with one great difficulty, that of "author synchronization". This difficulty explains the lag between volumes 1 and 2 of the series. Nevertheless we hope that the present volume will be appreciated as a valuable source of information on its central topic: How do cell organelles originate, and what mechanisms assure their continuity?

Download or read book Cellular Organelles written by Edward Bittar and published by Elsevier. This book was released on 1995-12-08 with total page 287 pages. Available in PDF, EPUB and Kindle. Book excerpt: The purpose of this volume is to provide a synopsis of present knowledge of the structure, organisation, and function of cellular organelles with an emphasis on the examination of important but unsolved problems, and the directions in which molecular and cell biology are moving. Though designed primarily to meet the needs of the first-year medical student, particularly in schools where the traditional curriculum has been partly or wholly replaced by a multi-disciplinary core curriculum, the mass of information made available here should prove useful to students of biochemistry, physiology, biology, bioengineering, dentistry, and nursing. It is not yet possible to give a complete account of the relations between the organelles of two compartments and of the mechanisms by which some degree of order is maintained in the cell as a whole. However, a new breed of scientists, known as molecular cell biologists, have already contributed in some measure to our understanding of several biological phenomena notably interorganelle communication. Take, for example, intracellular membrane transport: it can now be expressed in terms of the sorting, targeting, and transport of protein from the endoplasmic reticulum to another compartment. This volume contains the first ten chapters on the subject of organelles. The remaining four are in Volume 3, to which sections on organelle disorders and the extracellular matrix have been added.
