Arbuscular mycorrhizal (AM) fungi colonise plant roots, and by doing so forge the 'mycorrhizal uptake pathway(s)' (MUP) that provide passageways for the trade of resources across a specialised membrane at the plant-fungus interface. The transport of nutrients such as phosphorus (P), nitrogen and zinc from the fungus, and carbon from the plant, via the MUP have mostly been quantified using stable or radioactive isotope labelling of soil in a specialised hyphae-only compartment. Recent advances in the study of AM fungi have used tracing studies to better understand how the AM association will function in a changing climate, the extent to which the MUP can contribute to P uptake by important crops, and how AM fungi trade resources in interaction with plants, other AM fungi, and friend and foe in the soil microbiome.
