Dictyostelids


Book Description

Since their discovery in 1869, the dictyostelids have attracted the attention of scientists in a wide variety of fields. This interest has stemmed from their peculiar lifestyle and developmental properties, which were shaped by the evolutionary forces that generated multicellularity during eukaryotic evolution. More recently, the dictyostelids have gained attention due to the striking similarities found at the genomic, cellular and biochemical levels with human cells, which has propelled the species Dictyostelium discoideum to become a model system for biology and medicine in many laboratories. This book covers the latest advances in our knowledge of these extraordinary organisms with topics spanning from their evolutionary history, ecology and diversity to the recent discoveries regarding their cellular and molecular biology.




The Dictyostelids


Book Description

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


Book Description

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.

Biodiversity of Fungi


Book Description

Biodiversity of Fungi is essential for anyone collecting and/or monitoring any fungi. Fascinating and beautiful, fungi are vital components of nearly all ecosystems and impact human health and our economy in a myriad of ways. Standardized methods for documenting diversity and distribution have been lacking. A wealth of information, especially regrading sampling protocols, compiled by an international team of fungal biologists, make Biodiversity of Fungi an incredible and fundamental resource for the study of organismal biodiversity. Chapters cover everything from what is a fungus, to maintaining and organizing a permanent study collection with associated databases; from protocols for sampling slime molds to insect associated fungi; from fungi growing on and in animals and plants to mushrooms and truffles. The chapters are arranged both ecologically and by sampling method rather than by taxonomic group for ease of use. The information presented here is intended for everyone interested in fungi, anyone who needs tools to study them in nature including naturalists, land managers, ecologists, mycologists, and even citizen scientists and sophiscated amateurs. - Covers all groups of fungi - from molds to mushrooms, even slime molds - Describes sampling protocols for many groups of fungi - Arranged by sampling method and ecology to coincide with users needs - Beautifully illustrated to document the range of fungi treated and techniques discussed - Natural history data are provided for each group of fungi to enable users to modify suggested protocols to meet their needs




The Kingdom Fungi


Book Description

The ubiquitous fungi are little known and vastly underappreciated. Yet, without them we wouldn’t have bread, alcohol, cheese, tofu, or the unique flavors of mushrooms, morels, and truffles. We can’t survive without fungi. The Kingdom Fungi provides a comprehensive look at the biology, structure, and morphological diversity of these necessary organisms. It sheds light on their ecologically important roles in nature, their fascinating relationships with people, plants, and animals, and their practical applications in the manufacture of food, beverages, and pharmaceuticals. The book includes information about “true” fungi, fungus-like creatures (slime molds and water molds), and a group of “composite” organisms (lichens) that are more than just fungi. Particular attention is given to examples of fungi that might be found in the home and encountered in nature. The Kingdom Fungi is a useful introductory text for naturalists, mycologists, and anyone who wants to become more familiar with, and more appreciative of, the fascinating world of fungi.




Systematics and Evolution


Book Description

This volume includes treatments of systematics and related topics for both fungi and fungus-like organisms in four eukaryotic supergroups, as well as specialized chapters on nomenclature, techniques and evolution. These organisms are of great interest to mycologists, plant pathologists and others, including those interested in the animal parasitic Microsporidia. Our knowledge of the systematics and evolution of fungi has made great strides since the first edition of this volume, largely driven by molecular phylogenetic analyses. Consensus among mycologists has led to a stable systematic treatment that has since become widely adopted and is incorporated into this second edition, along with a great deal of new information on evolution and ecology. The systematic chapters cover occurrence, distribution, economic importance, morphology and ultrastructure, development of taxonomic theory, classification and maintenance and culture. Other chapters deal with nomenclatural changes necessitated by revisions of the International Code of Nomenclature for algae, fungi and plants, including the elimination of separate names for asexual states, as well as methods for preservation of cultures and specimens, character evolution and methods for ultrastructural study, the fungal fossil record and the impact of whole genomes on fungal studies.




Evolution of Fungi and Fungal-Like Organisms


Book Description

Sequence analyses of numerous fungal genomes over the past two decades have provided us with extensive insights into the phylogenetic relationships of fungi and the distribution of genes and their inferred functions, across the fungal kingdom. It is now possible to answer questions about the origin of the fungal kingdom and fungal evolution with an analytical precision that was not possible before. This fully revised and updated 2nd edition of The Mycota, Vol. 14, addresses major aspects of fungal evolution. The book is divided into four sections covering the following main topics: • Evolutionary roots of fungi • Evolution of pathogenic strategies • Evolution of mutualistic interactions • Evolution of metabolism and development in fungi Fungi are among the oldest eukaryotic groups in the living world. The aim of this book is to better understand the history and importance of fungi, as well as the characteristics that distinguish them from their sister group, the metazoans, and other fungus-like groups such as the slime molds and oomycetes. Many fungal species are important pathogens of animals and plants and have distinct but parallel pathogenicity strategies. Mutualistic interactions of fungi with other organisms are crucial for their survival in different ecological niches and have a great influence on their evolution and the design of their genomes. Metabolism is one of the most important features of life, and the diversity of metabolic processes is best understood by considering evolution. Studies of fungal metabolism have traditionally focused on metabolites of particular interest, namely mycotoxins, pathogenicity factors, antibiotics, and other compounds with interspecific activity. This volume will be of great interest to mycologists, evolutionary biologists, and fungal geneticists, as well as to lecturers and students of microbiology and mycology.




Dictyostelium discoideum Protocols


Book Description

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 Mycetozoans


Book Description

The Mycetozoans brings together, for the first time in a single volume, comprehensive information on the biology and classification of the mycetozoans and associated groups. The mycetozoans and their associates remain of prime interest to taxonomists and phylogenists because major new taxa continue to be discovered among them. This book informs the reader where to find mycetozoans, how to isolate and culture them, their life cycles and ultrastructure, and some of the experiments that may be performed with them. It presents studies on Protostelia (protostelids); Dictyostelia (dictyostelid cellular slime molds); Myxogastria (myxomycetes); Acrasea (acrasid cellular slime molds); Plasmodiophorina (plasmodiophorids); and Labyrinthulas (labyrinthulina and thraustochytrids). This text can serve as a reference tool in courses on mycetozoans, protozoology, mycology, and developmental biology of lower organisms, and as a concentrated source of information for research workers in all aspects of the biology and taxonomy of these organisms.
