We followed decomposition of pine needle litter and mor-layer humus over 3 yr in a factorial shrub removal- and pine root exclusion experiment in an old-growth Scots pine (Pinus sylvestris) forest, to evaluate effects of fungal guilds on mass loss. Litter mass loss was 23% greater when ectomycorrhizal fungi were excluded suggesting increased saprotrophic activity, independently of ericoid shrub presence. However, this 'Gadgil effect' was only found after 17 months following a summer drought. By contrast, humus mass loss was overall stimulated by ectomycorrhizal fungi, while ericoid mycorrhizal shrubs appeared to counteract this effect, potentially caused by simultaneous addition of recalcitrant organic matter and inhibition of ectomycorrhizal decomposers. We conclude that competitive saprotrophic-ectomycorrhizal fungal interactions may slow early-stage litter decomposition, but this effect was small and inconsistent. Furthermore, interactions between ecto- and ericoid mycorrhizal guild members appear to determine the late-stage organic matter balance of boreal forest humus.", "doi": "10.1111/nph.70316", "pmid": "40552521", "labels": {"National Genomics Infrastructure": "Service", "NGI Uppsala (Uppsala Genome Center)": "Service", "NGI Long read": "Service"}, "xrefs": [{"db": "pmc", "key": "PMC12329171"}], "notes": [], "created": "2025-08-19T13:22:00.173Z", "modified": "2025-08-19T13:22:00.288Z"}, {"entity": "publication", "iuid": "2087c60a5a82438891ed417372e22fe0", "links": {"self": {"href": "https://publications.scilifelab.se/publication/2087c60a5a82438891ed417372e22fe0.json"}, "display": {"href": "https://publications.scilifelab.se/publication/2087c60a5a82438891ed417372e22fe0"}}, "title": "Ectomycorrhizal fungi integrate nitrogen mobilisation and mineral weathering in boreal forest soil.", "authors": [{"family": "Mahmood", "given": "Shahid", "initials": "S", "orcid": "0000-0001-6280-4387", "researcher": {"href": "https://publications.scilifelab.se/researcher/af95eec78fe44938b73a8d1e91484b66.json"}}, {"family": "Fahad", "given": "Zaenab", "initials": "Z", "orcid": "0009-0000-5835-5160", "researcher": {"href": "https://publications.scilifelab.se/researcher/4c20dfdb0c7340778f20b1e239808c56.json"}}, {"family": "Bolou-Bi", "given": "Emile B", "initials": "EB", "orcid": "0000-0001-7803-3214", "researcher": {"href": "https://publications.scilifelab.se/researcher/488aee2af3a844d1b7fbbfcfde399d66.json"}}, {"family": "King", "given": "Katharine", "initials": "K", "orcid": "0009-0009-8075-9466", "researcher": {"href": "https://publications.scilifelab.se/researcher/2421e6cb187745cc909f72a6ac9375ee.json"}}, {"family": "K\u00f6hler", "given": "Stephan J", "initials": "SJ", "orcid": "0000-0001-9707-9023", "researcher": {"href": "https://publications.scilifelab.se/researcher/955fd789119a4e5f9ec314275095a70e.json"}}, {"family": "Bishop", "given": "Kevin", "initials": "K", "orcid": "0000-0002-8057-1051", "researcher": {"href": "https://publications.scilifelab.se/researcher/2cf39f8ead0744f591dcdbcb6caee99a.json"}}, {"family": "Ekblad", "given": "Alf", "initials": "A", "orcid": "0000-0003-4384-5014", "researcher": {"href": "https://publications.scilifelab.se/researcher/55b407368cf342698c0b681ef8cf2ba9.json"}}, {"family": "Finlay", "given": "Roger D", "initials": "RD", "orcid": "0000-0002-3652-2930", "researcher": {"href": "https://publications.scilifelab.se/researcher/9cf62270530f402faa530c435cb6829c.json"}}], "type": "journal article", "published": "2023-09-11", "journal": {"title": "New Phytol.", "issn": "1469-8137", "issn-l": "0028-646X"}, "abstract": "Tree growth in boreal forests is driven by ectomycorrhizal fungal mobilisation of organic nitrogen and mineral nutrients in soils with discrete organic and mineral horizons. However, there are no studies of how ectomycorrhizal mineral weathering and organic nitrogen mobilisation processes are integrated across the soil profile. We studied effects of organic matter (OM) availability on ectomycorrhizal functioning by altering the proportions of natural organic and mineral soil in reconstructed podzol profiles containing Pinus sylvestris plants, using 13 CO2 pulse labelling, patterns of naturally occurring stable isotopes (26 Mg and 15 N) and high-throughput DNA sequencing of fungal amplicons. Reduction in OM resulted in nitrogen limitation of plant growth and decreased allocation of photosynthetically derived carbon and mycelial growth in mineral horizons. Fractionation patterns of 26 Mg indicated that magnesium mobilisation and uptake occurred primarily in the deeper mineral horizon and was driven by carbon allocation to ectomycorrhizal mycelium. In this horizon, relative abundance of ectomycorrhizal fungi, carbon allocation and base cation mobilisation all increased with increased OM availability. Allocation of carbon through ectomycorrhizal fungi integrates organic nitrogen mobilisation and mineral weathering across soil horizons, improving the efficiency of plant nutrient acquisition.
