abstract = {To obtain insights into the dynamics of nutrient exchange
in arbuscular mycorrhizal (AM) symbiosis, we modelled
mathematically the two‐membrane system at the
plant–fungus interface and simulated its dynamics. In
computational cell biology experiments, the full range of
nutrient transport pathways was tested for their ability to
exchange phosphorus (P)/carbon (C)/nitrogen (N) sources. As
a result, we obtained a thermodynamically justified,
independent and comprehensive model of the dynamics of the
nutrient exchange at the plant–fungus contact zone. The
predicted optimal transporter network coincides with the
transporter set independently confirmed in wet‐laboratory
experiments previously, indicating that all essential
transporter types have been discovered. The thermodynamic
analyses suggest that phosphate is released from the fungus
via proton‐coupled phosphate transporters rather than
anion channels. Optimal transport pathways, such as cation
channels or proton‐coupled symporters, shuttle nutrients
together with a positive charge across the membranes. Only
in exceptional cases does electroneutral transport via
diffusion facilitators appear to be plausible. The
thermodynamic models presented here can be generalized and
adapted to other forms of mycorrhiza and open the door for
future studies combining wet‐laboratory experiments with
computational simulations to obtain a deeper understanding
of the investigated phenomena.},
