外生菌根真菌促生微生物生态功能研究进展

Ecological function of promoting microorganisms associated with ectomycorrhizal fungi

菌根的形成及功能与菌根促生功能微生物密切相关。外生菌根不仅在森林生态系统中发挥至关重要的作用,而且部分外生菌根类大型真菌具有良好的食药用经济价值。根据已有研究,本文系统阐述了外生菌根真菌相关促生功能微生物对外生菌根真菌菌根化、菌丝生长及子实体形成的促进作用及机制;解析促生功能微生物对外生菌根真菌的特异定殖机制;探讨外生菌根真菌相关促生性微生物的作用条件特异性及生态功能,对外生菌根真菌和相关促生功能微生物的互作进行综述,并展望了外生菌根真菌促生微生物的研究前景。希望为外生菌根真菌生长、发育及其生态功能研究提供新的思路。

Numerous studies have demonstrated that a lot of microorganisms, named mycorrhization helper bacteria, play an important role in driving mycorrhizal formation and function. Ectomycorrhizae is a key factor in forest ecosystem. Some ectomycorrhizal macrofungi are abundant and with medicinal and economic value. In this review, we summarized the effects of promoting microorganisms associated with ectomycorrhizal fungi on its functions and the underlying mechanisms for promoting mycorrhization, growth of fungal hyphae, and formation of fruitbody. We also explored the colonization mechanism of promoting microorganisms and its contextdependence as well as ecological function. Meanwhile, we reviewed the interaction between ectomycorrhizal fungi and these microorganisms. Then, we outlined the prospects of promoting microorganisms forfurther research and presented some new ideas for the research on growth, development, and ecological function of ectomycorrhizal fungi.
