The occurrence of symbiotic relationships between roots and fungi (mycorrhizas) has been recognized since the early I800’s and it is now clear that these associations are the most prevalent symbiotic systems on earth. Mycorrhizal associations can be found in all ecosystems and in important forest and crop species. Based on the structural features of the symbiosis between the plant and the fungus involved, seven categories have been described. Ongoing and more intensive investigations of mycorrhizas in the field and in regions of the world that have received little attention in the past, will likely result in the present categories being modified and perhaps expanded.
This book has resulted from a long collaboration among the authors and our shared interest in exploring the structural diversity of mycorrhizas at various scales. It has become clear from the literature and recent international meetings that a majority of the current research on mycorrhizas involves molecular, physiological and ecological studies. Few structural studies are being pursued in spite of the need for basic information for some categories of mycorrhizas and the detailed information that can now be obtained as a result of new-analytical methods. The intention of this book, therefore, is to provide, through a series of chapters. a summary of all the mycorrhizal categories from a morphological and anatomical perspective. Wc strongly believe that the structural information presented will provide researchers in all aspects of mvcorrhizal research with a platform from which to explore questions related to the functioning of mycorrhizas.
This book will be of interest to undergraduate and graduate students, secondary school teachers and professors W'ho include discussions of mycor-rhizas in various subjects that they teach, and researchers in root biology and various aspects of
mycorrhizas. We hope that the information included and the format of the book will stimulate readers to explore mycorrhizas in more detail. Leads are given into the literature for further discussion of each topic covered.
Most of the images presented in the chapters are from our own research. Credit is given for those images provided by other researchers and we thank them for allowing us to use them. Although some references are included in each chapter, no attempt has been made to provide a comprehensive literature review for each topic. Several recent reviews and volumes on mycorrhizas provide excellent detailed discussions of various aspects of mycorrhizal associations.
To provide the most complete descriptions of mycoưhizas, information has been sained by using a variety of preparative techniques combined with a range of microscopical methods. A brief appendix describing the various techniques used in preparing the images in the book is included. primarily as a guide for readers who are new to the field or have a background that does not include structural training. Also included is a glossary of the most common terms related to structural aspects of mycorrhizas.
Financial support has been provided indirectly by the Natural Sciences and Engineering Research Council of Canada by research grants over many years. We thank all of our former and present undergraduate, graduate, and post-doctoral students lor their excellent conưibutions. Cameron Ackerley and Melanie Ilowarth who. for years, helped US W'ith many aspects of microscopy. Linda Tackaberry for editorial assistance. Christopher Peterson for helping organize our literature data base, and the Universities of Guelph and Northern British Columbia for providing RLP and HBM time to launch this project.
