Mycorrhizal Symbiosis

In nature, the roots of most plants are colonized by symbiotic fungi to form mycorrhiza, which play a critical role in the capture of nutrients from the soil, and therefore in plant nutrition. Thirteen years have passed since the publication of the First Edition of Mycorrhizal Symbiosis, the book that has been generally acclaimed as the most definitive work on this fascinating topic. The Second Edition co-authored by Professor Sally Smith and Professor David Read has been completely rewritten to cover the significant advances in our understanding of this field. Key Features * Separate accounts of major mycorrhizal types, highlighting structure, development, physiology and ecology * Integrative treatment, covering nutrient transport, roles of mycorrhizas in ecology, applications in man-made environments, and interactions with pollutants * In depth treatment of evolutionary and developmental aspects, plus closer examination of external mycelium, and transport processes * Appreciation of diversity of form and function within major mycorrhizal types, and its importance in ecosystems

Recent years have seen extensive research in the molecular underpinnings of symbiotic plant-fungal interactions. Molecular Mycorrhizal Symbiosis is a timely collection of work that will bridge the gap between molecular biology, fungal genomics, and ecology. A more profound understanding of mycorrhizal symbiosis will have broad-ranging impacts on the fields of plant biology, mycology, crop science, and ecology. Molecular Mycorrhizal Symbiosis will open with introductory chapters on the biology, structure and phylogeny of the major types of mycorrhizal symbioses. Chapters then review different molecular mechanisms driving the development and functioning of mycorrhizal systems and molecular analysis of mycorrhizal populations and communities. The book closes with chapters that provide an overall synthesis of field and provide perspectives for future research. Authoritative and timely, Molecular Mycorrhizal Symbiosis, will be an essential reference from those working in plant and fungal biology.

This book offers a timely overview and synthesis of biogeographic patterns of plants and fungi and their mycorrhizal associations across geographic scales. Written by leading experts in the field, it provides an updated definition of mycorrhizal types and establishes the best practices of modern biogeographic analyses. Individual chapters address the basic processes and mechanisms driving community ecology, population biology and dispersal in mycorrhizal fungi, which differ greatly from these of prokaryotes, plants and animals. Other chapters review the state-of-the-art knowledge about the distribution, ecology and biogeography of all mycorrhizal types and the most important fungal groups involved in mycorrhizal symbiosis. The book argues that molecular methods have revolutionized our understanding of the ecology and biogeography of mycorrhizal symbiosis and that rapidly evolving high-throughput identification and genomics tools will provide unprecedented information about the structure and functioning of mycorrhizal symbiosis on a global scale. This volume appeals to scientists in the fields of plant and fungal ecology and biogeography.

The roots of most plants are colonized by symbiotic fungi to form mycorrhiza, which play a critical role in the capture of nutrients from the soil and therefore in plant nutrition. Mycorrhizal Symbiosis is recognized as the definitive work in this area. Since the last edition was published there have been major advances in the field, particularly in the area of molecular biology, and the new edition has been fully revised and updated to incorporate these exciting new developments. Over 50% new material Includes expanded color plate section Covers all aspects of mycorrhiza Presents new taxonomy Discusses the impact of proteomics and genomics on research in this area

In the years since the first edition of “Arbuscular Mycorrhizas: Physiology and Function” was published, an exceptional proliferation of interest in mycorrhizal biology has developed. This has been associated with advances in different research disciplines such as genetics, genomics, proteomics, metabolomics and physiology, advances which have generated better insight into topics of mycorrhizal biology, including the mechanisms of host-mycorrhiza interactions pre- and post-penetration, the influence of the symbiosis on the host and its surroundings, and the evolution and diversity of mycorrhization. It therefore became necessary to both update and expand the book's coverage in this, its second edition.

Fully covers the biology, biochemistry, genetics, and genomics of Medicago truncatula Model plant species are valuable not only because they lead to discoveries in basic biology, but also because they provide resources that facilitate translational biology to improve crops of economic importance. Plant scientists are drawn to models because of their ease of manipulation, simple genome organization, rapid life cycles, and the availability of multiple genetic and genomic tools. This reference provides comprehensive coverage of the Model Legume Medicago truncatula. It features review chapters as well as research chapters describing experiments carried out by the authors with clear materials and methods. Most of the chapters utilize advanced molecular techniques and biochemical analyses to approach a variety of aspects of the Model. The Model Legume Medicago truncatula starts with an examination of M. truncatula plant development; biosynthesis of natural products; stress and M. truncatula; and the M. truncatula-Sinorhizobium meliloti symbiosis. Symbiosis of Medicago truncatula with arbuscular mycorrhiza comes next, followed by chapters on the common symbiotic signaling pathway (CSSP or SYM) and infection events in the Rhizobium-legume symbiosis. Other sections look at hormones and the rhizobial and mycorrhizal symbioses; autoregulation of nodule numbers (AON) in M. truncatula; Medicago truncatula databases and computer programs; and more. Contains reviews, original research chapters, and methods Covers most aspects of the M. truncatula Model System, including basic biology, biochemistry, genetics, and genomics of this system Offers molecular techniques and advanced biochemical analyses for approaching a variety of aspects of the Model Legume Medicago truncatula Includes introductions by the editor to each section, presenting the summary of selected chapters in the section Features an extensive index, to facilitate the search for key terms The Model Legume Medicago truncatula is an excellent book for researchers and upper level graduate students in microbial ecology, environmental microbiology, plant genetics and biochemistry. It will also benefit legume biologists, plant molecular biologists, agrobiologists, plant breeders, bioinformaticians, and evolutionary biologists.

Studies of four hundred and sixty-five soybean (Glycine max (L.) Merr.) varieties from different parts of the world were conducted to determine their ability to grow in P-deficient soils and to determine the effect of vesicular-arbuscular (VA) mycorrhizal fungi on the ability of soybeans to grow in such P-deficient soils in the humid tropics.

The book begins with a chapter on Molecular Evolution and Phylogeny of mycorrhizas. Lucid discussions on cellular physiology, molecular genetics, and molecular regulation of nutrient exchange phenomenon in mycorrhizas form the core of this book. A comparative analysis of the molecular aspects of symbiosis and pathogenesis has been presented in detail. It also includes certain agriculturally useful aspects of disease control via mycorrhizas. Discussions on recent developments in molecular ecology of mycorrhizas, including most recently enunciated concepts such as ?nurse functions?, ?mycoheterotrophy? are provided in the book. Transformation, transgenics and genetic engineering of mycorrhizas is a unique and futuristic chapter. Applications of genetic engineering of mycorrhizas, as well as recently developed techniques of genetic transformation production of viable transgenic mycorrhizal fungi have been delineated. It will be useful to researchers/students involved in Microbiology, Molecular Biology, Plant Bio
