This book celebrates the careers of two highly influential Canadian researchers, Yolande Dalpé and J. André Fortin; it contains 14 chapters including reviews and case studies important to Canada or Canadian scientists. This focus has produced an interesting, if slightly eclectic, mix of subjects mainly based on Canadian systems but with a sprinkling of tropical or neo-tropical chapters. An introduction to mycorrhizal science is provided, emphasizing the role of Canadian research in the development of this area of science. There then follows a number of chapters concentrating on the arbuscular mycorrhizal symbiosis likely to be of greater interest to readers of this journal. There are some very interesting chapters here including fundamental work on, for example, the formation of different hyphal networks and on interactions with soil microbes. In the second half of the book the emphasis shifts to the ectomycorrhizal symbiosis which is more applied in nature. Chapters in both sections summarize attempts to use fungi as inoculants to improve plant growth. These, in general, highlight the requirement for a greater understanding of the interaction between symbionts and environment, which currently limits the development of effective inoculants. This need is perhaps best illustrated in the chapter summarizing the use of inoculation to aid restoration of oil sands. This book provides an interesting summary of the state of play of many important areas of mycorrhizal research and should prove interesting to a wide range of readers, although the understandable focus on Canadian-based work may limit its appeal.
