| 摘 要： | 丛枝菌根（arbuscular mycorrhizal，AM）真菌能与植物根系建立共生体提高植物抗病性。植物激素茉莉酸（jasmonic acid，JA）参与AM的形成，介导AM真菌诱导的植物抗病性。目前，关于AM真菌诱导的植物抗病性内容较为丰富，但是关于JA介导的AM真菌诱导的植物抗病性却有待进一步研究。本文首先总结了JA对AM形成和AM对植物内源JA积累的影响；其次介绍了AM真菌对植物抗病性影响及诱导机制；最后从诱导形成防御结构、提高酶活性及合成防御蛋白、诱导次生代谢物质合成、诱导调控信号分子、JA与其他激素相互作用五个方面探讨了JA在AM真菌诱导抗病性中的作用，并对本领域的研究方向进行展望，以期为植物病害防治和菌根研究提供可借鉴的思路。

| Abstract: | Arbuscular mycorrhizal fungi (AMF) can establish symbiosis with plant roots to improve plant disease resistance. The plant hormone jasmonic acid (JA) is involved in the formation of AM and mediates plant disease resistance induced by AM fungi. At present, there are a lot of literatures on AM fungi induction of plant disease resistance, but the plant resistance induced by JA-mediated AM fungi has yet to be further studied. In this review, firstly, the effects of JA on the establishment of AM symbiosis, AM symbiosis on the accumulation of JA in plants are discussed. Secondly, the influence of AM fungi on plant disease resistance and induction mechanism are introduced. Finally, the role of JA in the induction of disease resistance of AM fungi is discussed from five aspects, including the formation of defense structures, improving enzyme activity and synthesizing defense protein, inducing secondary metabolite synthesis, inducing and regulating signal molecules and the interactions between JA and other hormones. In addition, the research direction in this field is prospected, which provides useful ideas for plant disease prevention and mycorrhizal research. |
