Cell Biology of Physarum and Didymium, Volume II: Differentiation, Metabolism, and Methodology summarizes important experimental research using Physarum and Didymium for developmental and cellular studies. This book is organized into three parts, encompassing 28 chapters that cover the differentiation, metabolism, and experimental techniques for cellular studies. After presenting an introduction to some aspects of developmental biology, this volume describes the ultrastructure and physiology of sporulation, spore germination, encystment, excystment, spherulation, and spherule germination. This is followed by a discussion on regulatory events leading to morphogenesis and on biochemical, physiological, and structural data on the amoeboid stage. The second part focuses on metabolic aspects. This includes metabolic characteristics of myxomycetes; the formation of nucleotides in Physarum by de novo synthesis and from nucleic acid degradation products; and radiation and radiomimetic agents on myxomycete species. Considerable chapters in the concluding part are devoted to procedures and protocol for isolation of cell components from Physarum and Didymium species. This volume also evaluates some techniques, including electron microscopy, time-lapse microcinematography, phase-contrast microscopy, Feulgen staining, and culture methods. The concluding chapters examine the preparation, isolation, and characterization of ribonucleic acid, histone, plasmodial polysaccharides, myosin, actins, and fragmin. The book will serve as a frequent, single reference source to brief cell biologists on the primary research on Physarum and Didymium. It will also be a good source for graduate students in cell biology and perhaps in other graduate courses.

Genetic Expression in the Cell Cycle provides an understanding of the molecular mechanisms that govern the expression of genetic information during the cell cycle. The initial five chapters describe the intimate relationships between the supramolecular complexes that form the basic structure of chromatin. Emphasis is placed on the dynamics of cycle-dependent changes in the structural organization of some of these components. Subsequent chapters demonstrate that small nuclear RNAs (SnRNA) are actively involved in gene regulation in eukaryotic cells; discuss the relationship between cell cycle regulation in the yeast Saccharomyces cerevisiae and transcription of ribosomal RNA genes; and describe the use of conditional lethal mutants to study the regulation of the cell cycle of eukaryotic cells. The remaining chapters discuss the concepts and methodologies employed to isolate and study specific cell cycle mutants of S. cerevisiae; the antiproliferative effect of interferon on cultured human fibroblasts; and the role of cell membrane and related subcellular elements in the control of proliferation, differentiation, and cell cycle kinetics.

Premature Chromosome Condensation: Application in Basic, Clinical, and Mutation Research emerged from a workshop supported by the International Union against Cancer that reviewed the status of research on premature chromosome condensation and explored future possibilities, not least in relation to cancer. The workshop was held at the Institut für Humangenetik, Freie Universität Berlin, on September 6, 1980. The book begins with a review of the process of premature chromosome condensation. This is followed by separate chapters on the functional and morphological aspects of premature chromosome condensation; the behavior of prematurely condensed chromosomes (PCC) during mitosis in binucleate and multinucleate cells; chromosomes from spermatogenic cells; and micronucleus-derived PCC. Subsequent chapters discuss the application of banding techniques to the study of PCC; the factors involved in the condensation of interphase chromatin into chromosomes; and the induction of premature chromosome condensation in somatic plant cells. This book will be helpful to readers working in basic and applied research or in teaching. These include cytogeneticists, cell biologists, biochemists, and investigators in the field of mutation research.

Mutagenicity: New Horizons in Genetic Toxicology provides an overview of the various applications and studies in the field of genetic toxicology and environmental mutagenesis. The book is composed of selected scientific papers written by experts in the field. The text presents topics on naturally occurring mutagens; occupational carcinogen; and evaluation of cooking methods. Experiments on mammalian cell mutation; chromosomal aberrations; and organisms that can be used as environmental monitors of toxicity are discussed as well. Ecologists, environmental and sanitary engineers, toxicologists, and anyone interested in environmental mutagenesis, genetic toxicology, occupational health, or the regulation of toxic substances will find the book a good source of insight.

The Fifth International Biomineralization Symposium was held in May 1986 at The University of Texas at Arlington, Arlington, Texas. The chosen theme was the origin, evolution and modern aspects of biomineralization in plants and animals. Thus, the symposium was designed to bring together experts in ocean and atmospheric chemistry, geochemistry, paleontology, biology, medicine and related fields to share accumulated knowledge and to broaden research horizons. The contents of this volume reflect the diversified interests and views of contributors from these fields. Topics range from contrasting views of the origin of ocean chemistry, the cause or causes for the biomineralization among plants and animals, the evolution of style and structure of biomineralization, and the role of inorganic and organic compounds in biomineraliza tion. It was clear from those gathered in Arlington that the efforts of all researchers in any aspect of biomineralization can be strengthened and extended by greater exposure to the work of others in allied fields. At the time of this printing, several collaborative efforts have grown from interest and contacts developed during the symposium. Rex E. Crick viii ACKNOWLEDGEMENTS The symposium would not have occurred with the financial support of The Organized Research Fund of The University of Texas at Arlington and The Sea Grant Program administered by Texas A & M University. The staff of the Department of Geology of The University of Texas at Arlington were largely responsible for providing a pleasant atmosphere for learning.
