    摘要:

    丛枝菌根(Arbuscular mycorrhiza,AM)真菌是陆地生态系统中广泛存在的一类专性共生土壤微生物,是根系土壤区域中重要的功能菌群之一。AM真菌可侵染植物根系形成丛枝菌根共生体,改变植物根系形态和改善营养状况,从而提高宿主植物的生长发育、产量、质量和抗逆性。目前从烟草根系土壤分离报道的AM真菌已达13属54种,显示出烟草(Nicotiana tobacum L.)栽培的潜在AM真菌资源较为丰富。围绕烟草与AM真菌的共生效应,总结了影响AM真菌侵染和定殖烟草根系的主要因素,阐述了AM真菌对烟草生长、抗性生理及品质的影响,并对PGPR与AM真菌的协同作用进行了简要回顾,最后讨论了该领域存在的不足及今后展望;旨在为菌根技术运用于烟草栽培提供参考。

    Abstract:

    Arbuscular mycorrhizal (AM)fungi are ubiquitous soil microorganism in terrestrial ecosystem and are one of the important functional microorganisms in the soil-plant system.It can form a arbuscular mycorrhiza symbiotic system with plant roots by infecting the latter,which will significantly improve root morphology and nutrition,thereby improving the growth and development,yield,quality and stress resistance of host plant.At present,more than 13 genera and 54 species of AM fungi have been isolated from the roots rhizosphere soil of tobacco(Nicotiana tabacum L .)plant,which reveals that there are potential AM fungi resources for tobacco cultivation.This article focuses on the symbiosis effect of tobacco and AM fungi,summarizes the main factors that affect the AM fungi′s infection and colonization of tobacco roots,the role of AM fungi in tobacco growth,resistance physiology and quality were also elaborated.We also summarized the synergistic effect between PGPR and AM fungi,and outlined the shortcoming and prospects of it.All of this will provide reference for the application of mycorrhizal technology in tobacco cultivation.
