Ectomycorrhizal fungi decompose soil organic matter using oxidative mechanisms adapted from saprotrophic ancestors
Ectomycorrhizal fungi are thought to have a key role in mobilizing organic nitrogen that is trapped in soil organic matter (SOM). However, the extent to which ectomycorrhizal fungi decompose SOM and the mechanism by which they do so remain unclear, considering that they have lost many genes encoding lignocellulose-degrading enzymes that are present in their saprotrophic ancestors. Spectroscopic...
متن کاملEctomycorrhizal fungi in mineral soil
Ectomycorrhizal fungi are mutualistic symbionts of many forest trees and play a major role in nutrient uptake. They form diverse communities in boreal forest soils but functional differences within this group of fungi remain largely unknown. We study ectomycorrhzal fungi in mineral soil to determine how abiotic preferences influence their spatial distribution in stratified soil profiles. This i...
متن کاملColonizing success of saprotrophic and ectomycorrhizal basidiomycetes on islands.
The biodiversity of saprotrophic and ectomycorrhizal basidiomycetous macrofungi growing on seven islands in central Japan were compared to examine colonizing success within the context of island biogeography theory. Two hypotheses were tested: that the number of the fungal species depends on island area and that the slope of the species-area curve for saprotrophic and ectomycorrhizal macrofungi...
متن کاملIndependent roles of ectomycorrhizal and saprotrophic communities in soil organic matter decomposition
The relative roles of ectomycorrhizal (ECM) and saprotrophic communities in controlling the decomposition of soil organic matter remain unclear. We tested the hypothesis that ECM community structure and activity influences the breakdown of nutrient-rich biopolymers in soils, while saprotrophic communities primarily regulate the breakdown of carbon-rich biopolymers. To test this hypothesis, we u...
متن کاملDecomposition by ectomycorrhizal fungi alters soil carbon storage in a simulation model
Carbon cycle models often lack explicit belowground organism activity, yet belowground organisms regulate carbon storage and release in soil. Ectomycorrhizal fungi are important players in the carbon cycle because they are a conduit into soil for carbon assimilated by the plant. It is hypothesized that ectomycorrhizal fungi can also be active decomposers when plant carbon allocation to fungi is...
