AM真菌对植物抗逆性的影响及机制探讨

Effects of AM fungi on Plant Stress Resistance and the Mechanisms

菌根是真菌与植物根系形成的一种互惠共生体,其中内生菌根中的丛枝菌根(AM)真菌对植物生长以及耐受不良环境具有重要作用。本文总结了AM真菌在降低植物病虫害和提高植物抗旱、耐盐碱及耐重金属的效应,探讨AM真菌在提高植物抗逆性方面的作用机制,为应用AM真菌提高植物抗逆性提供参考。

Mycorrhiza is the symbiosis of fungi and plant roots,in which a kind of endophytic mycorrhiza,Arbuscular mycorrhiza(AM)fungi play an important role in plant growth and tolerance to hostile environments.This paper summarized the effects of AM fungi on reducing plant diseases and insect pests and improving plant resistance of drought,salt,heavy metal stress,and explored the mechanism of AM fungi in enhancing plant stress resistance.It may provide reference for the application of AM fungi to improve plant stress resistance.
