Where do root and fungus exchange resources?
Fit the specimen and set conditions before running.
External hyphae explore soil beyond the root surface. A branched arbuscule provides the interface for phosphate delivery toward the root and carbon supply toward the fungus.
Arbuscular mycorrhiza reciprocal budget: illustrative cost 2 µmol C per µmol P; no universal trading ratio and no claim that uncolonized roots cannot absorb nutrients.
Exchange phosphate toward the root and carbon toward the fungus.
Exchange phosphate toward the root and carbon toward the fungus.
