Arbuscular mycorrhiza (AM) are widely existing in soil ecosystems that formed by arbuscular mycorrhizal fungi with most of the terrestrial plants. Arbuscular mycorrhiza can improve plant salt tolerance. This article reviewed the domestic and international progresses that about the arbuscular mycorrhiza improving the salt resistance of plant. In the perspective of plant physiology, the mechanism that host plant response to salt stress in the help of AM associations were discussed. Meanwhile, several worthy of further exploration issues about regulation mechanism of AM against salt stress in molecular level were presented.

丛枝菌根广泛存在于土壤生态系统中,是丛枝菌根真菌与大多数陆生植物根系形成的一种内共生结构,能 提高宿主的耐盐性。 本文综述了近年来国内外关于丛枝菌根提高植物耐盐性方面的研究进展。 从植物生理层面,对 盐胁迫下丛枝菌根提高宿主植物耐盐性的响应机制进行了论述。 同时,也从分子水平总结了丛枝菌根调控植物获得 性耐盐机制方面值得深入探讨的问题。
