Part of the Progress in Botany book series (BOTANY, volume 63)


Mycorrhizae are by now a well-known feature of plant communities in terrestrial ecosystems. These symbioses, by definition, are mutualistic and always between plants and fungi localized in the root or rhizoid, and are found in every terrestrial ecosystem except the Dry Valleys of Antarctica. For over a century, the importance of mycorrhizae in facilitating (and occasionally inhibiting) nutrient uptake by plants has been documented for hundreds of plant species and in many different soils and environmental conditions.
