Root Associations

Roots can have a symbiotic (mutually beneficial) association with other organisms, in particular:
• Mycorrhiza (which are fungi), e.g. Betula pendula (Silver Birch) and many other woodland trees.
• Rhizobium (bacteria), e.g. the root nodules on plants in the Pea family (Fabaceae, previously Leguminosae), such as clover plants.
