Systematics And Evolution Of Fungi

Examining the progress and shifts that have taken place towards understanding fungi, this volume examines most of the major groups, including Chytridiomycota, Zygomycota, Ascomycota, and Basidiomycota. Topics include advances in morphological and molecular taxonomy of the highly toxigenic Fusarium species, understanding the phylogeny of the alterna

Mycology, the study of fungi, originated as a subdiscipline of botany and was a des criptive discipline, largely neglected as an experimental science until the early years of this century. A seminal paper by Blakeslee in 1904 provided evidence for self incompatibility, termed "heterothallism", and stimulated interest in studies related to the control of sexual reproduction in fungi by mating-type specificities. Soon to follow was the demonstration that sexually reproducing fungi exhibit Mendelian inheritance and that it was possible to conduct formal genetic analysis with fungi. The names Burgetf, Kniep and Lindegren are all associated with this early period of fungal genet ics research. These studies and the discovery of penicillin by Fleming, who shared a Nobel Prize in 1945, provided further impetus for experimental research with fungi. Thus began a period of interest in mutation induction and analysis of mutants for biochemical traits. Such fundamental research, conducted largely with Neurospora crassa, led to the one gene: one enzyme hypothesis and to a second Nobel Prize for fungal research awarded to Beadle and Tatum in 1958. Fundamental research in biochemical genetics was extended to other fungi, especially to Saccharomyces cerevisiae, and by the mid-1960s fungal systems were much favored for studies in eukaryotic molecular biology and were soon able to compete with bacterial systems in the molecular arena.

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.

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.

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.
