摘要: 丛枝菌根(AM)真菌作为一类在全球分布广泛的土壤微生物,能够与陆地上大多数的维管植物形成专性共生关系,对于植物营养吸收和生态系统功能具有重要作用.而较少量的维管植物如苋科、黎科、石竹科、十字花科等植物被认为是非菌根植物.目前,对于这些非菌根植物与AM 真菌之间的相互作用关系研究少且分散,缺乏系统总结.本文综述了非菌根植物的类型以及低侵染的原因,邻体植物形成的菌丝网络对AM真菌侵染非菌根植物的影响,并探讨AM真菌和非菌根植物之间可能存在的相互作用,以及植物-AM真菌之间的物质交换及可能存在的生态功能,旨在为进一步发挥非菌根植物在脆弱生态系统的功能潜力提供新思路.

Abstract: As a kind of globally widely distributed soil microorganism, arbuscular mycorrhizal (AM) fungi form the symbiosis with the majority of land plants, which is important for plant nutrition and ecosystem functioning. Few vascular species are considered to be nonmycorrhizal, especially those within the families Amaranthaceae, Chenopodiaceae, Carophyllaceae and Brassicaceae. At present, the interactions between these non-host plants and AM fungi are few and scattered, lacking systematic summary. In this paper, the type of non-host plants, the reason of low mycotrophy, and the effect of AM network formed by neighbor plants on AM fungi colonization on the non-host, and the possible interaction between AM fungi and non-host, as well as the material exchange between plants and AM fungi and their possible ecological functions were reviewed in order to give some new ideas on the function of the nonmycorrhizal plants in the fragile ecosystems.
