Ectomycorrhizal fungi - potential organic matter decomposers, yet not saprotrophs

Lindahl, Bjorn D. and Tunlid, Anders LU (2015) In New Phytologist 205(4). p.1443-1447
Abstract
Although hypothesized for many years, the involvement of ectomycorrhizal fungi in decomposition of soil organic matter remains controversial and has not yet been fully acknowledged as an important factor in the regulation of soil carbon (C) storage. Here, we review recent findings, which support the view that some ectomycorrhizal fungi have the capacity to oxidize organic matter, either by brown-rot' Fenton chemistry or using white-rot' peroxidases. We propose that ectomycorrhizal fungi benefit from organic matter decomposition primarily through increased nitrogen mobilization rather than through release of metabolic C and question the view that ectomycorrhizal fungi may act as facultative saprotrophs. Finally, we discuss how mycorrhizal... (More)
