Molecular Mechanisms of Arbuscular Mycorrhiza Symbiosis Formed by Arbuscular Mycorrhiza Fungi and Host-plants

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.
