摘要
丛枝菌根(arbuscular mycorrhizal,AM)是球囊菌门真菌与植物根系组成的共生体系,71%的维管植物有AM。球囊菌门(Glomeromycota)现下设1纲4目11科27属,约有300种丛枝菌根真菌(arbuscular mycorrhizal fungi,AMF)。AMF可以提高植物对干旱、盐度、重金属等非生物胁迫和由其他生物引起的生物胁迫的抵抗力以及调节植物次生代谢产物的合成。本文综述了AMF对植物逆境胁迫和次生代谢产物影响的研究进展。阐述了AMF对植物形态结构、生理生化、基因表达和次生代谢等生命活动的影响。总结了AMF提高植物逆境胁迫抗性和调节植物次生代谢产物合成方面的作用机理。旨在为深入研究AMF响应植物逆境胁迫和调节植物次生代谢产物合成的作用机理提供参考。
Arbuscular mycorrhizal(AM)is a symbiotic system composed of the fungi of the phylum Glomeromycota and plant roots.Seventy-one percent of vascular plants have AM.Glomeromycota is now under a single class,four orders,eleven families and twenty-seven genera,with about 300 species of arbuscular mycorrhizal fungi(AMF).AMF improves plant resistance to abiotic stresses such as drought,salinity,heavy metals,and biotic stresses induced by other organisms as well as regulates the synthesis of plant secondary metabolites.This article reviews the research progress on the effects of AMF on plant adversity stress and secondary metabolites.The effects of AMF on life activities such as plant morphology and structure,physiology and biochemistry,gene expression and secondary metabolism are described.The mechanism of action of AMF in enhancing plant resistance to adversity stress and regulating the synthesis of plant secondary metabolites is summarized.It aims to provide a reference for the in-depth study of the action mechanism of AMF in response to plant adversity stress and regulation of plant secondary metabolite synthesis.
