摘　　要：菌根真菌是多种真菌类群的异质群,与90%以上的植物根有关。外生菌根(ECM)在森林生态系统中种类繁多、分布广泛、适应性强,是天然林的重要组成。菌根化可以促进宿主植物对水分和营养元素的吸收,对宿主植物的定植、生长和抗逆性等具有重要影响。因此,研究其在胁迫下的响应机制对于更好地利用外生菌根真菌—植物联合修复污染土壤有着重要意义。目前对外生菌根真菌提高植物耐胁迫能力的机制还不甚了解。文中综述菌根化植物的生长特征、抗胁迫能力以及转录组和蛋白质组表达水平等的研究进展,分析菌根真菌增强宿主植物耐胁迫能力,并提出有待深入研究的方向,以期为揭示ECM植物抵抗胁迫机制、探索外生菌根真菌—树木联合修复技术的相关研究提供参考和借鉴。Mycorrhizal fungi are a heterogeneous group of multiple fungal taxa that are associated with more than 90% of plant roots.Ectomycorrhizal mycorrhizae(ECM) are diverse,widely distributed and adaptable in forest ecosystems and they are an important component of natural forests.Mycorrhizalization promotes the uptake of water and nutrients by host plants,and plays an important role in host plant colonization,growth,and stress resistance.Therefore,Mycorrhizalization promotes the uptake of water and nutrients by host plants,and plays an important role in host plant colonization,growth,and stress tolerance.Therefore,the study of the response mechanism of ECM under stress is of great significance for better employing ECM and their host plants to remediate polluted soil.Currently,the mechanisms by which ectomycorrhizal fungi enhance plant stress tolerance are poorly understood.In this paper,we review the progress of the research on growth characteristics,stress resistance,transcriptome and proteome expression levels of mycorrhizalized plants,analyze the ability of mycorrhizal fungi to enhance the stress tolerance of host plants,and propose directions for further research.We hope to provide references and insights for revealing the stress resistance mechanism of ECM plants and exploring the joint restoration technology of ectomycorrhizal fungi and trees.
