Insoluble Phosphate Fixation in Mineral Soils
Orthophosphate ions bond tightly with aluminum and iron in acid soils, and calcium in alkaline soils, creating insoluble mineral complexes inaccessible to plant roots.
Extra-Radical Hyphae Secretion of Organic Acids
AMF hyphae secrete citrate and oxalate anions that displace bound phosphate, while specialized fungal high-affinity phosphate transporters absorb free ions.
Arbuscular Nutrient-Carbon Trade at the Periarbuscular Membrane
Inside root cortical cells, branched fungal arbuscules deliver phosphorus and zinc in exchange for host-plant hexose sugars and lipids.
