| Research Abstract |
In arbuscular mycorrhizal (AM) symbiosis which is comprised of plant and AM fungi, we investigated how N affects AM fungal function and physiology. We obtained the results suggesting that polyphosphate accumulation in AM fungal hyphae which is an index of the fungal P uptake is coupled with N assimilation, and also suggesting that AM fungal P uptake is regulated by soil mineral N concentration.
