Part of the The Mycota book series (MYCOTA, volume 9)


Sequencing projects, whole genome expression analysis, and extensive field studies have dramatically broadened our view on ectomycorrhizal development and function. The aim of this review is to summarize and comment on current concepts of ectomycorrhizal fungal carbon nutrition, its prerequisites and consequences for the fungus as well as for its plant partner. We discuss fungal carbon uptake and conversion into metabolites by soil-growing hyphae and those of the plant–fungus interface of functional ectomycorrhizas. Furthermore, we talk about long-distance transport metabolites, necessary for carbohydrate distribution within the fungal colony. After reviewing the basics of fungal C-nutrition, established and novel concepts of plant-derived fungal carbon support are discussed. Based on potential fungal carbohydrate sources in symbiosis, putative plant carbon export mechanisms are described. Furthermore, plant strategies of controlling the fungal sugar support are summarized. As a result, the reader will be provided with a comprehensive summary of the current research status.
