菌根真菌提高植物抗旱性機制的研究回顧與展望 Review 菌物學報 852 Review and prospect of researches on the mechanisms of mycorrhizal fungi in improving plant drought resistance LIU Na ZHAO Ze Yu JIANG Xi Ling XING Xiao Ke Institute of Medicinal Plant Development Peking Union Medical College Chinese Academy of Medical Sciences Beijing 100193 China Abstract Mycorrhizal fungi have an extensive symbiotic relationship with about 97 of vascular plants across the world Quantities of researches show that mycorrhizal plants own higher tolerance to drought than non mycorrhizal plants indicating that mycorrhizal fungi play an important role in plant drought resistance In this paper the mechanism of mycorrhizal fungi in assisting host plants to resist drought was summarized Three main aspects are included the effect of mycorrhizal fungi on physiological characteristics of plants under drought stress molecular mechanisms of mycorrhizal fungi in enhancing drought resistance of plants and influence of mycorrhizal fungi on plant secondary metabolic pathways Currently researches on physiological mechanisms of plant drought resistance under enhancement of mycorrhizal fungi are comparatively deepgoing while the researches of other two aspects are relatively weak With the development of molecular biology technology the molecular mechanism of mycorrhizal fungi enhancing plant drought resistance and related metabolic pathways will be further revealed Hopefully this paper provides a helpful reference to Chinese researchers in theoretical research of mycorrhizal interaction and development of functional
