Abstract: Naturally occurring arbuscular mycorrhizae (AM) are the result of long-term evolution between plant and soil fungi. This symbiosis role can promote fungi and host plants to have an important adaptability. In recent years, the interaction mechanisms of AM fungi and host plants, as well as the establishment of AM symbiosis have been widely studied. In this review, molecular signaling pathways of AM symbiosis are discussed. The signal transduction pathway in asymbiotic stage, the early stages of plant-fungus interactions and the maintenance of symbiotic phase are general summarized.

Key words: Arbuscular mycorrhizal, Fungi, Plants, Symbiosis

摘要: 土壤真菌与植物形成的丛枝菌根在自然界中广泛存在,是植物在长期的生存过程中,与菌根真菌一起共同进化的结果。这种共生作用可以引起真菌和其宿主植物发生重要的适应性变化。近年来,丛枝菌根真菌与寄主植物之间是如何相互发生作用并形成菌根共生体,是人们所关注的问题。本文主要对丛枝菌根共生体形成的信号途径,对真菌与植物相互作用的非共生阶段的信号释放、共生初期阶段植物代谢及信号识别机制,共生体的稳定维持进行了综述。
