【摘要】：丛枝菌根(arbuscular mycorrhizal,AM)真菌是生态系统中重要的土壤微生物之一。AM真菌菌丝体网络是由AM真菌菌丝体在土壤生态系统中连接两株或两株以上植物根系所形成的菌丝体网络。随着菌根学研究的深入,如何直观的揭示AM真菌的生态学功能已经成为相关领域关注的热点问题。研究发现,利用同位素示踪技术可以开展AM真菌与宿主植物对土壤矿质营养的吸收、转运等方面的研究,以及菌丝体网络对不同宿主植物之间营养物质的分配研究和AM真菌在生态系统生态学中的功能研究。基于此,为了阐明同位素示踪技术在AM真菌研究中的价值,围绕菌根学最新研究进展,系统回顾了利用同位素示踪技术探究AM共生体对不同元素吸收和转运的机制、同位素示踪技术在AM真菌菌丝体网络研究中的价值和利用同位素示踪技术研究AM真菌在生态系统中的功能,为AM真菌生态学功能的研究提供理论基础,并对本领域未来的研究方向和应用前景进行展望。
[Abstract]:Arbuscular mycorrhizal (arbuscular mycorrhizal,AM) fungi are one of the most important soil microbes in the ecosystem. The AM fungal mycelium network is a mycelial network formed by the AM fungal mycelium connecting two or more plant roots in the soil ecosystem. With the development of mycorrhizal research, how to reveal the ecological function of AM fungi has become a hot issue in related fields. It was found that isotopic tracer technique could be used to study the uptake and transport of mineral nutrients in soil by AM fungi and host plants. The distribution of nutrients between different host plants and the function of AM fungi in ecosystem ecology were also studied by mycelium network. In order to elucidate the value of isotopic tracer technique in the study of AM fungi, the mechanism of absorption and transport of different elements by AM symbionts was systematically reviewed. The value of isotopic tracer technique in the study of mycelial network of AM fungi and the function of AM fungi in ecosystem by using isotope tracer technique provide a theoretical basis for the study of the ecological function of AM fungi. The future research direction and application prospect of this field are prospected.
