The am fungus could obtain adequate carbon resources for itself, thus ensuring normal growth and metabolic activit y owing to the efflux of carbohydrate from the plasma membrane of the host root cortical cells to the interface of the symbiosis. thirdly, the structure and composition of the root cortex cellular plasma membrane kept good integrity and the leakage of carbohydrate maintained at low level when the plant obtained enough p and metabolizes normally. although enough carbohydrate was synthesized by plant, the am fungi could not obtain enough energy, resulting in inhibition of growth of the extraradical hyphae and decreased metabolic activity of the am fungi
由此，我們認為植物磷營養狀況調控菌根真菌生長和代謝活性的機制是：當植物處于嚴重缺磷脅迫時，不能合成足夠的碳水化合物供給自身生長的需要，也不能向真菌提供額外的碳水化合物，因而菌根真菌生長受阻，代謝活性較低；當植物中度缺磷時，根皮層細胞質膜的組成和結構不完整，通透性大，碳水化合物通過質膜向外的滲漏量大，菌根真菌因而獲得充足的碳源，保證真菌正常的生長和旺盛的代謝；當植物獲得足夠的磷而使體內磷營養代謝正常時，其細胞質膜組成和結構完整，碳水化合物的滲漏量保持在較低的水平，盡管此時植物合成了足夠的碳水化合物，但菌根真菌仍不能獲得足夠的能量，導致真菌生長受阻和代謝活性降低。
