Issue Date: | 2022 | Publisher: | NATURE PORTFOLIO | Source: | Communications Biology, 5 (1) , p. 398 (Art N° 398) | Abstract: | Chemical profiles of arbuscular (AM) and ectomycorrhizal (EM) fungi reveal that differences in decomposability-relevant chemistry are larger between AM and EM fungi than across plant functional groups. The chemical quality of soil carbon (C) inputs is a major factor controlling litter decomposition and soil C dynamics. Mycorrhizal fungi constitute one of the dominant pools of soil microbial C, while their litter quality (chemical proxies of litter decomposability) is understood poorly, leading to major uncertainties in estimating soil C dynamics. We examined litter decomposability of arbuscular mycorrhizal (AM) and ectomycorrhizal (EM) fungal species using samples obtained from in vitro cultivation. We showed that the chemical composition of AM and EM fungal mycelium differs significantly: EM fungi have higher concentrations of labile (water-soluble, ethanol-soluble) and recalcitrant (non-extractable) chemical components, while AM fungi have higher concentrations of acid-hydrolysable components. Our results imply that differences in decomposability traits among mycorrhizal fungal guilds represent a critically important driver of the soil C cycle, which could be as vital as is recognized for differences among aboveground plant litter. | Notes: | Huang, W (corresponding author), Leiden Univ, Inst Environm Sci, Environm Biol, Einsteinweg 2, NL-2333 CC Leiden, Netherlands.; Huang, W (corresponding author), Hasselt Univ, Ctr Environm Sci, Martelarenlaan 42, B-3500 Hasselt, Belgium. w.huang@cml.leiden.univ.nl |
