Dictyostelium by Richard H. Kessin Pdf

Dictyostelia are soil amoebae capable of extraordinary feats of survival, motility, chemotaxis, and development. Characterised by their ability to transform from a single-celled organism into an elaborate assemblage of thousands of synchronously-moving cells, Dictyostelids are often referred to as 'social amoebae', and have been the subjects of serious study since the 1930s. Research in this area has been instrumental in understanding many problems in cellular biology. Beginning with the history of Dictyostelids and discussing each stage of their development, this book considers the evolution of this unique organism, analyses the special properties of the Dictyostelid genome, and presents in detail the methods available, at the time of the book's original publication in 2001, to manipulate their genes. Representing the synthesis of such material and with an emphasis on combining classical experiments with modern molecular findings, this book will be essential for researchers and graduates in developmental and cellular biology.

Dictyostelium discoideum Protocols by Ludwig Eichinger Pdf

Dictyostelium discoideum is a simple but fascinating eukaryotic microorg- ism, whose natural habitat is deciduous forest soil and decaying leaves, where the amoebae feed on bacteria and grow as independent single cells. Exhaustion of the bacterial food source triggers a developmental program, in which up to 100,000 cells aggregate by chemotaxis towards cAMP. Morphogenesis and cell different- tion then culminate in the production of spores enabling the organism to survive unfavorable conditions. Dictyostelium offers unique advantages for studying f- damental cellular processes with the aid of powerful molecular genetic, bioche- cal, and cell biological tools. These processes include signal transduction, chemotaxis, cell motility, cytokinesis, phagocytosis, and aspects of development such as cell sorting, pattern formation and cell type differentiation. Recently, D- tyostelium was also described as a suitable host for pathogenic bacteria in which one can conveniently study the process of infection. In addition, Dictyostelium has many of the experimental conveniences of Saccharomyces cerevisiae and is pr- ably the best experimentally manipulatable protozoan, providing insight into this diverse group of organisms, which includes some of the most dangerous human parasites. The recent completion of the Dictyostelium genome sequencing project strengthens the position of D. discoideum as a model organism. The completed genome sequence and other valuable community resources constitute the source for basic biological and biomedical research and for genome-wide analyses.

The Development Of Dictyostelium Discoideum by William Loomis Pdf

The Development of Dictyostelium discoideum consists of 11 chapters representing the 11 major aspects at which continuous progress are made in the study of Dictyostelium discoideum. This book begins with the discovery, classification, ecology, and development of Dictyostelium discoideum. It then outlines the advances in genetic manipulation and mutant isolation of the organism. Much of the advances in cell biology have been related to a better understanding of the composition and function of the cell membrane. Hence, analyses of Dictyostelium plasma membranes are collated. This reference material also describes the role of chemoattractants in organizing cell movements and the intracellular events triggered by occupancy of chemoreceptors. It also explains the understanding of the macromolecular components of the chemosensory system of Dictyostelium discoideum. It further discusses the cell motility, cell adhesion, morphogenetic signaling, cytodifferentiation, and gene expression in the species. Finally, the phenomenon of cell-type specification and regulation in this organism is addressed. This book will be valuable for those already familiar with the general outlines of Dictyostelium biology.

The Dictyostelids by Kenneth Bryan Raper Pdf

Kenneth Raper tells how dictyostelids are isolated, cultivated, and conserved in the laboratory; how myxamoebae aggregate to form multicellular pseudoplasmodia; how fructifications arise by transformation of amoeboid cells into stalk cells and spores; and how similar cells can, under certain conditions, enter a sexual phase. For each known dictyostelid Professor Raper includes a complete description and photographic illustrations; one new species is described. Originally published in 1984. The Princeton Legacy Library uses the latest print-on-demand technology to again make available previously out-of-print books from the distinguished backlist of Princeton University Press. These editions preserve the original texts of these important books while presenting them in durable paperback and hardcover editions. The goal of the Princeton Legacy Library is to vastly increase access to the rich scholarly heritage found in the thousands of books published by Princeton University Press since its founding in 1905.

Dictyostelium Discoideum by William Loomis Pdf

Dictyostelium Discoideum: A Developmental System presents D. discoideum as a model eukaryotic system to study a variety of developmental problems. The book describes the life cycle of the organism D. discoideum which exists in nature as a soil amoeba in forest detritus. The nuclei of D. discoideum contain DNA, RNA, and proteins which have properties similar to those of histones present in calf thymus nuclei. The unique sequences of the genome of the organism code for the gene products synthesize during its growth and development. One approach in genetic analyses to understanding the developmental processes of the organism is to isolate a large number of morphological mutants. The isolation process will indicate the number of variations that are open to the developing system, and will point to causal connections between stages. The text also explains that the number of cells which differentiate into stalk cells is the result of timing and mechanics of the process of culmination. Ashworth (1971) suggests that cells in pseudoplasmodia of D. discoideum adjust their positions in relation to the chemical structure of the sheath itself. A model shows how cells communicate their response to the sheath in an axial fashion. The book can prove beneficial for biochemists, micro-biologists, cellular researchers, and investigators involved in the study of cellular biology.

Signal Transduction During Biomembrane Fusion by Danton H. O'Day Pdf

Signal Transduction during Biomembrane Fusion begins with three review articles that put the problem of signal transduction and biomembrane fusion into a general perspective. Each subsequent chapter begins with an introduction which reviews past work on a specific biological system. The authors' current research is then detailed. The chapters conclude with final comments wherein the contributors express viewpoints about the general significance and progression of their work. This book comprises 12 chapters, with the first focusing on signal transduction during biomembrane fusion. The succeeding chapters then discuss the ""focal membrane fusion"" model; osmotic phenomena in membrane fusion; cell signaling and regulation of exocytosis at fertilization of the egg; and signal transduction during exocytosis in mast cells. Other chapters cover protein kinase c and granule membrane fusion; GTP-binding proteins and formation of secretory vesicles; and signal transduction during phagocytosis. The remaining chapters discuss calcium signal transduction pathway and myoblast fusion; phospholipid metabolism during calcium-regulated myoblast fusion; protein kinase c, membrane protein phosphorylation, and calcium influx in chick embryo skeletal myoblast fusion; and signal transduction and cell fusion in dictyostelium. This book will be of interest to practitioners in the fields of neurobiology, zoology, and the biological sciences.

Evolution of Fungi and Fungal-Like Organisms by Stefanie Pöggeler,Johannes Wöstemeyer Pdf

Based on sequence analyses of many different genes, the past decade has provided us with a profound knowledge of fungal systematics and phylogeny. In addition, a number of sequences of complete fungal genomes have been identified and several others will soon follow. In this volume, leading experts address questions concerning the origin of the fungal kingdom and fungal evolution at a level of analytical refinement that has never been possible before. The following major aspects are highlighted: evolutionary roots of fungi; evolution of signaling in fungi and fungal-like organisms; evolution of mutualistic systems and metabolism in fungi; and evolutionary mechanisms and trends.

The Social Amoebae by John Tyler Bonner Pdf

Noted biologist and author John Tyler Bonner has experimented with cellular slime molds for more than sixty years, and he has done more than anyone else to raise these peculiar collections of amoebae from a minor biological curiosity to a major model organism--one that is widely studied for clues to the development and evolution of all living things. Now, five decades after he published his first pioneering book on cellular slime molds, Bonner steps back from the proliferating and increasingly specialized knowledge about the organism to provide a broad, nontechnical picture of its whole biology, including its evolution, sociobiology, ecology, behavior, and development. The Social Amoebae draws the big lessons from decades of research, and shows how slime molds fit into and illuminate biology as a whole. Slime molds are very different from other organisms; they feed as individual amoebae before coming together to form a multicellular organism that has a remarkable ability to move and orient itself in its environment. Furthermore, these social amoebae display a sophisticated division of labor; within each organism, some cells form the stalk and others become the spores that will seed the next generation. In The Social Amoebae, Bonner examines all these parts together, giving a balanced, concise, and clear overview of slime mold biology, from molecules to cells to multicells, as he advances some unconventional and unexpected insights.
