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 colour plate section .Covers all aspects of mycorrhiza .Presents new taxonomy .Discusses the impact of proteomics and genomics on research in this area.
