Arbuscular mycorrhizae(AM) is a widely distributed plant-fungal symbiosis in natural ecosystem.Herbivore is a general ecological process in grassland ecosystem.In order to discover the ecological stretegies among AM fungi-plant-animal,the interrelation between AM fungi and herbivore and the response of host plant on their cooperative effects were studied in this review,and three points were discussed:1) the research about herbivore on AM fungi colonization and AM fungi spores population,2) the influence of AM on animals behaviors,especially the Insects gather their foods,and 3) the responses of plants to their cooperative effects.Finally research perspectives were also given out in this field.
丛枝菌根(AM)真菌和根瘤菌是两类重要的共生微生物,分别能够与宿主植物形成丛枝菌根和根瘤,其中,对二者共有的宿主植物——豆科植物而言,则能够形成AM真菌-豆科植物-根瘤菌三重共生体.两类微生物与宿主植物共生关系建立的关键是二者之间的相互识别以及随后的侵染,其相互识别过程就是它们相互交换信号分子、相互作用的过程,而这两类微生物与宿主植物的识别过程具有许多相似之处.本文就根瘤菌、AM真菌与宿主植物在分子水平上的共生机理进行了综述,在对宿主植物分泌信号分子识别的基础上,提出植物根系对两类微生物侵染的感应机制,分析了共生体形成过程中相关基因的转录与表达,进而阐明了共生体的形成过程,并对本领域的未来发展提出了建议.
