丛枝菌根真菌与深色有隔内生真菌生态修复功能与作用

生态修复是目前全球关注的热点问题,如何增加植被的覆盖度及生态修复效率是目前研究的重点。丛枝菌根真菌(arbuscular mycorrhiza fungi,AMF)和深色有隔内生真菌(dark septate endophyte,DSE)均是自然界植物根际分布广泛的一类内生真菌,均能与植物形成菌根共生体,具有一定的促进植物生长、抵抗逆境及修复污染土壤等功能与作用,在生态修复中具有广泛的应用潜力。本文综述了AMF及DSE两种微生物的功能、作用及其在生态修复应用中的研究进展,并进一步对AMF和DSE在生态修复中存在的问题和前景进行展望。

Functions of arbuscular mycorrhizal fungi and dark septate endophytes in ecological restoration

The needs to increase vegetation coverage and plants’immunity in ecological restoration are important topics of current research.Microbe-assisted phytoremediation has been considered as the most promising technology for the remediation of ecology.Arbuscular mycorrhizal fungi(AMF)and dark septate endophyte(DSE)are soil-borne beneficial fungi that form root-fungus association with plant roots and provide a variety of benefits to the host plants.Moreover,AMF and DSE generally help plants uptake nutrient better and can enhance plant tolerance to many biotic and abiotic stresses,and thus they can be used to control fungal diseases and promote plant growth in extreme environment and polluted soil.The purpose of the present research is to investigate the function and application of AMF and DSE in ecological restoration and provide a basis in studying synergic mechanisms by these fungi.The possible problems and prospects of AMF and DSE in ecological restoration are involved.
