Book Description
Endosymbiosis is a primary force in eukaryotic cell evolution. In order to understand the molecular mechanisms involved in this mutualistic relationship, experiments to reproduce endosymbiosis are indispensable. The ciliate "Paramecium" is an ideal host for performing such studies. Topics presented in this volume are: the origins of algal and bacterial symbionts in "Paramecium", the diversity of endosymbiotic bacteria, such as "Holospora" bacteria and especially "Chlorella" species, as well as the infection and maintenance processes. The metabolic control, the regulation of circadian rhythms and photobiological aspects of the mutualistic association, as well as the killer effect of "Paramecium" and its causative agents are further points discussed.

Book Description
Symbiotic associations involving prokaryotes occur ubiquitously and are ecologically highly significant. In symbiotic associations, co-evolution of the partner organisms has led to specific mechanisms of signal exchange and reciprocal regulation, and resulted in novel physiological capabilities of the association as compared to those of the individual partners. Symbiosis research has recently entered an exciting era because molecular biology techniques are available for studying partner organisms in association and in a culture-independent manner. It is the goal of this book to contribute towards a broader perspective and an understanding of the function of symbiotic systems. 14 different model systems have been chosen, comprising well known symbioses as well as novel experimental systems which have only recently become amenable to experimental manipulation.

Book Description
Bacterial taxonomy as a specialized discipline is practised by a minority but the applications of taxonomy are important to most, if not all microbiologists. It is the implementation of taxonomic ideas and practises which gives rise to identification and typing systems, procedures for the analysis and characterization of biodiversity, hypotheses about the evolution of micro-organisms, and improved procedures for the isolation and implementation of bacteria in biotechnological processes. Without taxonomic theory providing a sound basis to these many facets of microbiology there would be severe problems faced by many scientists working with micro-organisms. Taxonomy comprises three sequential but independent processes; classification, nomenclature and identification. The first two stages are the prime concern of the specialist taxonomist but the third stage should result in identification schemes of value to all microbiologists. As the classification and identification of micro-organisms improves, largely due to the introduction of new technologies, so does its contribution to the subject as a whole. It therefore seemed timely to hold a conference in the autumn of 1993 devoted to microbial identification. Such a topic could not be addressed without some reference to the enabling discipline of classification, but the principal aims were to assess improvements in identification and typing and how these were benefiting microbiological topics ranging from ecological and biotechnological studies of extremophilic bacteria to the use of pyrolysis mass spectrometry in epidemiology. The meeting, which was held in Granada, Spain, was supported by FEMS (FEMS Symposium No.

Book Description
Viruses of Fungi and Simple Eukaryotes focuses on the developments in and experimental approaches to the study of fungi and simple eukaryotic viruses. Emphasizing molecular biology and genetics, the book provides the first comprehensive description of lower eukaryotic viruses. Featuring the work of more than 45 international authorities, the book includes more than 1,000 citations, numerous illustrations, tables, and micrographs. It discusses both retrovirus and reovirus systems in simple eukaryotes and examines how simple eukaryotes can serve as important models for research in eukaryotic molecular and cell biology. The book also covers a diverse group of RNA and DNA viruses, describes possible applications of fungi and simple eukaryotes to biotechnological, agricultural, and medicinal products, and explains the significance of lower eukaryotic viruses to biological control. Key topics covered include protein secretion and processing, nucleic acid enzymology, yeast biology, plant pathology, and human pathogenic yeast killer systems.

Book Description
Transposon tagging can work. Even though most of our understand ing about the factors that contribute to a successful tagging experiment has been accumulated from a limited number of experiments using different transposable elements in different genetic backgrounds, it is still possible to draw some conclusions regarding the best experimental strategies for gene tagging. In our experience, Spm has proved to be a good element for transposon tagging. The frequency of recovering mutable alleles in duced by Spm is not significantly different from that for Ac-Ds or for Mu 6 (summarized in Ref. 22) and varies from about 10- to 10=zr:-8pm has the unique advantage, however, in that all of the members of thiSfumily that have been examined thus far are homologous to each other at the DNA level. Therefore, by combining molecular analysis with genetic segre gation, it is possible to identify and isolate alleles that are due to insertions of either autonomous or nonautonomous Spm elements. There are definite steps one can take to increase the chances of de tecting a transposition into the gene of interest. The most important step is to select a genetic background in which the desired phenotype will be easy to screen. If the phenotype is not likely to be mutable, then tester lines should be constructed so as to contain flanking markers that can aid in subsequent segregation analyses.

Book Description
All life is chemical. That fact underpins the developing field of ecological stoichiometry, the study of the balance of chemical elements in ecological interactions. This long-awaited book brings this field into its own as a unifying force in ecology and evolution. Synthesizing a wide range of knowledge, Robert Sterner and Jim Elser show how an understanding of the biochemical deployment of elements in organisms from microbes to metazoa provides the key to making sense of both aquatic and terrestrial ecosystems. After summarizing the chemistry of elements and their relative abundance in Earth's environment, the authors proceed along a line of increasing complexity and scale from molecules to cells, individuals, populations, communities, and ecosystems. The book examines fundamental chemical constraints on ecological phenomena such as competition, herbivory, symbiosis, energy flow in food webs, and organic matter sequestration. In accessible prose and with clear mathematical models, the authors show how ecological stoichiometry can illuminate diverse fields of study, from metabolism to global change. Set to be a classic in the field, Ecological Stoichiometry is an indispensable resource for researchers, instructors, and students of ecology, evolution, physiology, and biogeochemistry. From the foreword by Peter Vitousek: "[T]his book represents a significant milestone in the history of ecology. . . . Love it or argue with it--and I do both--most ecologists will be influenced by the framework developed in this book. . . . There are points to question here, and many more to test . . . And if we are both lucky and good, this questioning and testing will advance our field beyond the level achieved in this book. I can't wait to get on with it."
