Developmental Biology in Prokaryotes and Lower Eukaryotes

‘Developmental biology’ is widely understood as processes, which mainly concern embryonic animal development and differentiation of cells and tissue. It is also often defined as the timeline for the evolutionary developmental biology of eukaryotic multicellular higher organisms, i.e., plants and animals. The development of prokaryotes and lower eukaryotes in contrary has been neglected for a long time, which was the motivation for publishing this book. This book highlights one of Darwin's most important findings: Evolution is a creative, but not a conscious process. It also illustrates that this concept does not only apply to multicellular higher organisms, but affects every form of life. The reader shall find complex biochemical and genetic pathways of bacteria, yeasts or protozoa, comparable to those exhibited by plants or animals. The molecular mechanisms of dramatic genome rearrangements, recombination and horizontal gene transfer that are responsible for evolutionary adaptations are discussed. Additionally, the book covers bacteria of the genera Myxobacteriales and Caulobacterales, which are able to develop tissue-like cellular organization. The morphogenesis of entomopathogenic fungi and the endosymbiont theory are also addressed. The book is a useful introduction to the field for junior scientists, interested in bacteriology, protistology and fungal development. It is also an interesting read for advanced scientists, giving them a broader view of the field beyond their area of specialization.

Master Control Genes in Development and Evolution

In this fascinating book, one of the world's most eminent developmental biologists discusses some of the exciting new insights into how genes control development. Walter Gehring describes in vivid detail his essential contributions to the landmark discovery of the homeobox, a characteristic DNA segment found in the genes of all higher organisms from the fruitfly to humans, and he explains how this has provided the key to our modern understanding of development and evolution. The book thus becomes not only a lucid discussion of genetics but also an engaging description of the art of scientific investigation. Gehring begins his story by looking at the work of the many researchers who laid the foundation for the fields of molecular, cellular, and developmental biology, providing insightful vignettes of past and present investigators. He then describes his laboratory's hunt for the gene that caused odd mutations in the fruitfly--in which, for example, antennae on the head were transformed into legs. He explains that researchers eventually found that the same master control genes that dictate the body plan in flies also pattern human bodies, limbs, hands, heart, and brain. And he illustrates the universality of the genetic control of development by describing the development of the eye; eyes as different as those of humans, squids, and flies, he shows, develop under the same master control gene.

Genetic Mosaics and Cell Differentiation

In cases where this is not possible, the fate of the cells has to be examined by using cell markers. Most suitable for this purpose are genetic markers, provided that they do not interfere with the developmental pathway to be studied.

Genetic Mosaics and Cell Differentiation

The relationship of cell lineage and differentiation is one of the most intriguing problems in developmental biology. In most higher organisms, the analysis of the cell lineage has to rely on indirect methods. Only in the most suitable systems, like the nematodes, can the pattern of cell division be determined by direct observation under the microscope. In cases where this is not possible, the fate of the cells has to be examined by using cell markers. Most suitable for this purpose are genetic markers, provided that they do not interfere with the developmental pathway to be studied. However, suitable genetic markers and techniques for generating genetic mosaics are available in a few organisms only. Therefore, this volume is largely concerned with Drosophila and the mouse, which have been studied most extensively. In 1929 STURTEVANT introduced the analysis of gynandromorphs into devel opmental genetics. However, this important contribution remained largely unnoticed until the late sixties, when the potential of this technique for deter mining embryonic fate maps and the number of primordial cells was exploited, and the methodology extended to the mapping of mutational foci. Mitotic recombination was demostrated by STER:-

Developmental Plasticity and Evolution

This book solves key problems that have impeded a definitive synthesis in the past.

Developmental Plasticity and Evolution

The first comprehensive synthesis on development and evolution: it applies to all aspects of development, at all levels of organization and in all organisms, taking advantage of modern findings on behavior, genetics, endocrinology, molecular biology, evolutionary theory and phylogenetics to show the connections between developmental mechanisms and evolutionary change. This book solves key problems that have impeded a definitive synthesis in the past. It uses new concepts and specific examples to show how to relate environmentally sensitive development to the genetic theory of adaptive evolution and to explain major patterns of change. In this book development includes not only embryology and the ontogeny of morphology, sometimes portrayed inadequately as governed by "regulatory genes," but also behavioral development and physiological adaptation, where plasticity is mediated by genetically complex mechanisms like hormones and learning. The book shows how the universal qualities of phenotypes--modular organization and plasticity--facilitate both integration and change. Here you will learn why it is wrong to describe organisms as genetically programmed; why environmental induction is likely to be more important in evolution than random mutation; and why it is crucial to consider both selection and developmental mechanism in explanations of adaptive evolution. This book satisfies the need for a truly general book on development, plasticity and evolution that applies to living organisms in all of their life stages and environments. Using an immense compendium of examples on many kinds of organisms, from viruses and bacteria to higher plants and animals, it shows how the phenotype is reorganized during evolution to produce novelties, and how alternative phenotypes occupy a pivotal role as a phase of evolution that fosters diversification and speeds change. The arguments of this book call for a new view of the major themes of evolutionary biology, as shown in chapters on gradualism, homology, environmental induction, speciation, radiation, macroevolution, punctuation, and the maintenance of sex. No other treatment of development and evolution since Darwin's offers such a comprehensive and critical discussion of the relevant issues. Developmental Plasticity and Evolution is designed for biologists interested in the development and evolution of behavior, life-history patterns, ecology, physiology, morphology and speciation. It will also appeal to evolutionary paleontologists, anthropologists, psychologists, and teachers of general biology.

Evolutionary Developmental Biology

Although evolutionary developmental biology is a new field, its origins lie in the last century; the search for connections between embryonic development (ontogeny) and evolutionary change (phylogeny) has been a long one. Evolutionary developmental biology is however more than just a fusion of the fields of developmental and evolutionary biology. It forges a unification of genomic, developmental, organismal, population and natural selection approaches to evolutionary change. It is concerned with how developmental processes evolve; how evolution produces novel structures, functions and behaviours; and how development, evolution and ecology are integrated to bring about and stabilize evolutionary change. The previous edition of this title, published in 1992, defined the terms and laid out the field for evolutionary developmental biology. This field is now one of the most active and fast growing within biology and this is reflected in this second edition, which is more than twice the length of the original and brought completely up to date. There are new chapters on major transitions in animal evolution, expanded coverage of comparative embryonic development and the inclusion of recent advances in genetics and molecular biology. The book is divided into eight parts which: place evolutionary developmental biology in the historical context of the search for relationships between development and evolution; detail the historical background leading to evolutionary embryology; explore embryos in development and embryos in evolution; discuss the relationship between embryos, evolution, environment and ecology; discuss the dilemma for homology of the fact that development evolves; deal with the importance of understanding how embryos measure time and place both through development and evolutionarily through heterochrony and heterotrophy; and set out the principles and processes that underlie evolutionary developmental biology. With over one hundred illustrations and photographs, extensive cross-referencing between chapters and boxes for ancillary material, this latest edition will be of immense interest to graduate and advanced undergraduate students in cell, developmental and molecular biology, and in zoology, evolution, ecology and entomology; in fact anyone with an interest in this new and increasingly important and interdisciplinary field which unifies biology.

The Evolution of Genetics

The Evolution of Genetics provides a review of the development of genetics. It is not intended as a history of the science of heredity. By a brief and general survey, however, it seeks to show the connections of past to present research, and of current discoveries to future investigations. The book opens with a chapter on the legacy of classical genetics. This is followed by separate chapters on the use of microorganisms in molecular genetics; the structure and replication of genetic material; mutation and recombination of genetic material; the heterocatalytic function of genetic material; and concludes with a discussion of the future of genetics. Undergraduates considering a career of teaching or research in biology, students who are embarking on graduate studies in biology, professional biologists working in fields other than genetics but interested in current research on heredity, and laymen who have had some education in biology and have a continued interest in biological science may find something useful in this book.

Drosophila as a Model Organism for Ageing Studies

The present book aims to be both more modest and more ambitious. It focuses on a single object (Drosophila), but attempts to off er a synthesis of all the gerontological work that has been done on it.

Drosophila as a Model Organism for Ageing Studies

Many books on ageing attempt to cover the whole field of gerontology. However, since gerontology is now such a diversified and rapidly expanding subject, the results of such attempts tend to be either incomprehensible compendia or encyc10pedias of disheartening size. The present book aims to be both more modest and more ambitious. It focuses on a single object (Drosophila), but attempts to off er a synthesis of all the gerontological work that has been done on it. It also aims to show the extent to which this work has led to an understanding of the biological phenomena of ageing, longevity, senescence and death in higher organisms, inc1uding man. Finally it attempts, on the basis of current knowledge, to mark out the paths that the next generation of researchers will most probably follow. Drosophila has been used as a model organism to advance our basic knowledge of the fundamentals of genetics and gerontology. It may be noted that the pioneering work on the genetics of ageing, which used Drosophila, began very early in this century, within the first decade of the rediscovery of Mendel's laws.

The Study of Gene Action

Although the physical nature of the gene was essentially clear by the late 1950s, the study of gene action, particularly during the development of higher organisms, is ongoing. Wallace and Falkinham explain how intimately progress has relied on technology. Initially limited to an examination of external features and subsequently to classical genetics and cytogenetic analyses, research was revolutionized by Watson and Crick's discovery of the double helix structure of DNA.

Early Embryonic Development of Animals

Four of the major animal systems studied for the mechanisms of their early embryonic development are treated in this volume. The articles address the specific questions studied in the various systems, discuss the fundamental questions raised by the particular organism and explain the techniques used to find answers to these questions. Questions of patternformation, early organogenesis and the genetics of the early development arecovered as well as the question of parental imprinting phenomena in mammals which are important for the early differentiation. The development of the mouse, Drosophila, Caenorhabditis and the zebrafish is emphasized by leading experts of their fields, and current problems in each system are exposed. For the zebrafish the advantages of this new system for developmental biology studies are summarized and discussed in their values, while in the other system the emphasis is laid on one of the actual field of research.

Plant Physiology 10

Plant Physiology: A Treatise, Volume X: Growth and Development explores the physiology of plant growth and development, considering the morphogenesis and morphogenetic systems, dormancy, environmental cues in plant growth and development, plant senescence, the role of hormones in growth regulation, cell division, and growth and development in space. This volume is organized into eight chapters and begins with an introduction to morphogenesis as a developmental phenotype, emphasizing the cell and the shoot. The next chapters cover events in the life of the plant, reflecting the importance of the whole plant concept to the subject, and the ways in which these events are controlled and integrated into environmental signals and events. An experimental approach to a model system for dormancy is described, and then the discussion shifts to senescence and death of plants as aspects of plant development. This volume also presents a clear and illuminating overview of the major plant growth regulators and their modes of action. This book also introduces the reader to cell division and its effect on most major developmental events after fertilization, along with the genetic analysis of development and its control by genes. The final chapter focuses on the integration of plant growth studies with the technology of space travel, which permits analysis of plant behavior in the complete absence of gravity. This book is intended for researchers, students, and specialists in related fields who wish to gain insight on the concepts and research trends in plant growth and development.

Nucleic Acid Hybridization in the Study of Cell Differentiation

Sound in theory, the method is in a honing phase as regards the technical detail. This is expressed in the hesitation with which some of the conclusions are rightly drawn.

Nucleic Acid Hybridization in the Study of Cell Differentiation

The informational content of cells is encoded in the nucleotide sequences of their DNA. The restrictions on base pairing- A pairing with T (U), and G pairing with C - in nature assures the fidelity of replication of DNA in cell division, and of transcription. In the test tube, these restrictions can be exploited for ascertaining similarities and dissimilarities of nucleic acids of varying origin by measuring the kinetics of reassociation of polynucleotides to double-stranded molecules in DNA DNA renaturation or RNA-DNA hybridization experiments, and by determining the thermal stability and other physical-chemical properties of the resulting hybrid molecules. This method has enormous potential for developmental biology. It offers a more direct approach to the ever-present question of the genetic identity of different cell types in an individual organism, and a more direct test of the hypothesis of diffe rential gene function. It offers the possibility of localizing genes on chromosomes without the use of Mendelian genetics. It is an indispensable tool in the isolation, purification, and characterization of genes. This volume brings together six articles by investigators actively working on various aspects of developmental biology who use nucleic acid hybridization as a tool in their research. Sound in theory, the method is in a honing phase as regards the technical detail. This is expressed in the hesitation with which some of the conclusions are rightly drawn.

Hierarchical Genome And Differentiation Waves  The  Novel Unification Of Development  Genetics And Evolution  In 2 Volumes

Over the past few decades numerous scientists have called for a unification of the fields of embryo development, genetics, and evolution. Each field has glaring holes in its ability to explain the fundamental phenomena of life. In this book, the author shows how the phenomenon of cell differentiation, considered in its temporal and spatial aspects during embryogenesis, provides a starting point for a unified theory of multicellular organisms (plants, fungi and animals), including their evolution and genetics. This unification is based on the recent discovery of differentiation waves by the author and his colleagues, described in the appendices, and illustrated by a flip movie prepared by a medical artist. To help the reader through the many fields covered, a glossary is included.This book will be of great value to the researcher and practicing doctors/scientists alike. The research students will receive an in-depth tutorial on the topics covered. The seasoned researcher will appreciate the applications and the gold mine of other possibilities for novel research topics.
