The present book highlights importance of mycorrhiza in soil genesis wherein it reflects mycorrhizal occurrence and diversity, various tools to characterize them and its impact on soil formation/health together with crop productivity. The edited compendium provides glimpses on the mycorrhizal fungi and their prominent role in nutrient transfer into host plants, and presenting view on application of mycorrhiza for crop biofortification. It focuses on the mechanisms involve in weathering process employed by mycorrhiza with highlighting the current and advanced molecular approaches for studying mycorrhizal diversity. Further, book emphasizes following aspects in details: significance of AMF in phytoremediation of hydrocarbon contaminated sites, the role of mycorrhiza in soil genesis using scientometric approach, the concept of mycorrhizosphere, xenobiotic metabolism, molecular approaches for detoxifying the organic xenobiotics and the role of mycorrhizosphere in stabilizing the environment in an eco-friendly way. In addition, the book will be benign to researchers that involved in mycorrhiza characterization especially by deploying metagenomics/PCR based and non PCR based molecular techniques that may be utilized to study the microbial diversity and structure within the mycorrhizosphere.

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.

Depuis la première édition de ce livre, en 2008, plus de 10 000 nouvelles contributions à la connaissance des mycorhizes ont été publiées. Voilà pourquoi cette nouvelle édition augmentée et mise à jour a paru nécessaire. Les mycorhizes sont formés par des champignons microscopiques qui font merveille en horticulture en travaillant en symbiose avec les racines des plantes. Les champignons aident les plantes à puiser des éléments nutritifs dans le sol et à s'adapter au milieu. En échange, les plantes fournissent aux champignons l'énergie qu'ils sont incapables de tirer eux-mêmes du soleil.Au cours des dernières années, une multitude de travaux ont clairement démontré l'intérêt scientifique et pratique de ces symbioses pour l'ensemble des végétaux du monde entier. Pourtant, en dépit de ces preuves répétées et irréfutables, un grand nombre de praticiens en horticulture, en agriculture, en foresterie et en environnement comprennent encore mal l'importance concrète de ce phénomène. C'est dans cet esprit que les auteurs ont préparé cette nouvelle édition qui vise à la fois à faire comprendre la biologie des mycorhizes dans ce qu'elle a de plus fascinant et à montrer comment en tirer profit dans de très nombreux aspects de la culture des plantes et de leur protection, tout en assurant le maintien des équilibres naturels.

The book provides basic knowledge in mycorrhizal ecology, knitted with novel conceptual frameworks and contemporary perspectives, especially in the context of global change. In a fast changing world wherein anthropogenic climate change, biological invasions, deforestation, desertification, and frequent droughts have become routine hard realities, the contents of this book urge readers to rethink basic notions of setting and accomplishing objectives in mycorrhizal research to make sense vis-à-vis contemporary challenges. In this book, a global perspective of mycorrhizal diversity and distribution is provided, followed by some insights into the impact of various global change elements such as climate change, plant invasion, and extreme environmental conditions on mycorrhizas and the role of these mutualists in turn to help their host plants to withstand such novel selection pressures. Special attention here is given to the interesting, but largely neglected, topics such as the role of mycorrhizas in ecological restoration of degraded environments and mycorrhizal status of aquatic plants. The basic idea is to unify various topical areas in mycorrhizal science in an integrated framework. This book can be used by the undergraduate and graduate level students studying mycorrhizal symbioses in the context of current ecological applications. The materials in this book will benefit biological scientists actively involved in research on mycorrhizal ecology and global environmental change. Besides, the contents of the book could be of special interest to restoration ecologists and biodiversity managers.

Mycorrhiza will be the focus of research and study for the coming decade. Successful survival and maintenance of plant cover is mostly dependent on mycorrhization. During the last decade about ten books have appeared on various aspects of mycorrhiza, including two on methodology. The present book has been compiled to give a complete and comprehensive description of the topic to the students and researchers in botany, applied mycology, biotechnology, forestry and agriculture. The book will also be useful to planners dealing with biofertilizers and forestation. Besides topics of academic interest, the volume includes several aspects which are unique and are written about for the first time, e.g.: Arbuscular Mycorrhizal symbiosis - recognition and specificity; Mycorrhizal Integration and cellular compatibility between Endomycorrhizal symbionts; Cost - economics of existing methodology for inoculum production of vesicular-arbuscular mycorrhizal fungi; Mycorrhiza: Ecological Implications of Plant interactions; Outplanting performance of mycorrhizal inoculated seedlings; Fluorescence microscopy in mycorrhiza studies and Ectomycorrhizal fungi as experimental organism. Other aspects not mentioned above include most recent reviews concerning vesicular-arbuscular mycorrhiza and ectomycorrhizae. The different review chapters have been written by world authorities in their respective specialisations giving more up to date information than is provided anywhere else. This book deals with all major aspects of mycorrhiza, giving structure, ultrastructure, ecology and applications in agriculture and forestry.

Mycorrhizal symbioses are central to the multitrophic interactions that impact plant productivity, competitiveness and survival. This book integrates present-day knowledge from well-known research groups on some of the topics which are at the forefront of mycorrhizal research. Topics include the cell programmes that drive mycorrhiza formation and function, the processes sustaining symbiotic mutualism, stress response mechanisms in mycorrhizal symbionts, and the diversity and ecological impacts of mycorrhizal systems. The efficient management of mycorrhizal systems has the potential to support the sustainable production of quality foods while ensuring environmental quality for future generations.

This book is intended to be a record of the Biotechnology-Assisted Re/Afforestation Project in the Asia-Pacific Region (BIO-REFOR) since 1992, conducted in coop­ eration with the International Union of Forest Research Organizations (lUFRO). The purpose of the project is to promote exchanges of information of fundamental research on indigenous species in the Asia-Pacific Region in order to restore natural forests. The production, cultivation, and maintenance of forest tree species provide highly sustainable production systems that conserve soils, the microenvironment, and biodiversity The key technology for biomass production of forests is propagation via micropropagation or traditional propagation. However, there are many recalci­ trant species among useful forest trees to be propagated in large numbers. Recent advances in mycorrhizal technology and in vitro culture have made it possible to commercially propagate useful trees for re/afforestation. In this book, comprehensive information is provided on propagation, mycor­ rhizal inoculation, and reforestation of economically and environmentally impor­ tant forest trees, information that usually is available only in widely scattered re­ sources. Here, we include a wide area of the ecology and physiology of dipterocarps as a general overview, and then cover propagation techniques, mycorrhizal symbio­ sis, man-made forests, and biodiversity in the Asia-Pacific region.

The?rst 30 cm of the earth's surface represents a fragile and valuable ecos- tem, thanks to which terrestrial plants, and indirectly animals and humans, can live. The microbial activity occurring in soil is largely responsible for its physical and nutritional quality. Among the micro-organisms living in soil, the arbuscular mycorrhizal (AM) fungi play a major role. They are present in all types of soil, everywhere on the planet, living in symbiotic association with the roots of most plant species. They have co-evolved with plants for 400 million years, improving their nutrition and resistance to v- ious types of stress. Present practices in conventional agriculture, which introduce great amounts of chemicals, have eliminated or underexploited the AM symbiosis. The rational exploitation of AM fungi in sustainable agriculture, to help minimize the use of chemical fertilizers and pesticides, has been hampered by several biological characteristics of these mic- organisms: they cannot be grown in the absence of a plant host and their genetic structure is very complex. Despite these limitations, biologists have made important progress in understanding better the functioning of AM fungi. An in vitro technique has been developed using mycorrhizal root organ cultures, which made it possible to investigate the genetics, cell biology and physiology of AM fungi. We can now be objective enough to critically evaluate the impacts the in vitro technique has had to improve our knowledge on mycorrhizal symbiosis.

Plant conservation is increasingly recognised as an outstanding global priority, yet despite considerable efforts over the last few decades, the number of threatened species continues to rise. The practice of plant conservation has for too long been a rather hit-or-miss mixture of methods. While microorganisms have been recognised as a crucial and essential element in supporting the lifecycles of plant species, there has been limited recognition of the relationships between macro level conservation facilitating ecosystem functioning at the micro level. This book addresses the role of microorganisms in conservation - both their support functions and deleterious roles in ecosystem processes and species survival. Importantly, a number of authors highlight how microbial diversity is, itself, now under threat from the many and pervasive influences of man. What is clear from this volume is that like many contemporary treatments of plant and animal conservation, the solution to mitigate the erosion of biodiversity is not simple. This book represents an attempt to bring to the fore the ecological underwriting provided by microorganisms.

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
