Abstract: Arbuscular mycorrhizal (AM) fungi is an important microorganism widely existed in agro-ecosystem,which can improve the resistance of plants to biological stress such as pests and diseases. Insects is an important part of the ecosystem. Both AM fungi and insects depend on plants to obtain the nutrients and food needed for growth,and they can also affect each other. The new progress of research on AM fungi-insect interaction since 2015 was summarized in this article. AM fungi can protect plant against insects by improving plant growth and whole healthy,regulating plant volatiles,changing in plant chemicals,and regulating related defense gene expression. AM fungi also promote the synthesis of other compounds,which are beneficial to the growth,development and reproduction of insects. Plant can also resist the stress caused by insects through their own defense system. Insect-feeding plants affect the distribution of nutrients in plants,reduce the rate of AM fungal infection and the number of arbuscular branches,vesicles,it also affect the normal function of AM fungi. At the same time,the research on the field of AM fungi-insect interaction is prospected,and suggestions for future research are put forward.

摘要: 丛枝菌根(arbuscular mycorrhizal,AM)真菌广泛存在于农业生态系统中,可提高作物对害虫、病害等生物逆境的抗性。昆虫是生态系统的重要组成部分,AM真菌与昆虫均依赖植物,获取生长所需的养分与食物,二者亦可相互影响。本文归纳了2015年以来AM真菌与昆虫互作研究的新进展,研究发现AM真菌可促进植物生长、提高植物整体抗虫性,亦可通过调控植物挥发性物质、植物体内化学物的变化、相关防御基因表达增强植物对昆虫的防御能力,还能促进其他化合物的合成从而有利于昆虫的生长、发育和繁殖;同时昆虫采食植物影响植物体内养分的分配,从而减少AM真菌侵染率、丛枝和泡囊数量以及影响AM真菌正常的功能。本文还对AM真菌与昆虫互作领域的研究进行了展望,对今后研究提出了建议。
