Carbohydrates and Nitrogen: Nutrients and Signals in Ectomycorrhizas

  • Chapter

Due to plant litter, forest soil is rich in complex carbohydrates (e.g., cellulose and lignin). Nevertheless, these carbohydrates are only slowly degraded by specialized microorganisms and thus forest soils are rather poor in readily cleavable carbohydrates that are necessary for the growth of the majority of microbes including ectomycorrhizal fungi.

Basidiomycetes are able to transfer nutrients and metabolites over long distances. Exploring a rich source of readily utilizable carbohydrates would thus favor the colonization of other soil areas, too. The association with fine roots of woody plants forming ectomycorrhizas is a way that secures exclusive access to such a rich carbohydrate source for ectomycorrhizal fungi.
