报告摘要：

Arbuscular mycorrhizal (AM) fungi establish a symbiotic relationship with more than 70% of land plants and provide host plants with mineral nutrients in exchange for carbon sources. Since AM fungi play important roles in the terrestrial ecosystem and are used in agriculture as biofertilizers, understanding AM symbiosis is important for basic science and developing a sustainable agriculture system. An interesting but troublesome feature of AM fungi is obligate biotrophy. They produce spores only when they colonize host plants. This feature strictly hinders both basic research and agricultural use of AM fungi, because we need host plants to produce AM fungus inoculums, which is costly and time-consuming. We found that specific fatty acids induce spore formation in AMF and established the axenic culture system fur AM fungi, which would be a breakthrough for the production of AMF inoculums. Furthermore, our recent results suggest that plant-derived compounds induce the expression of genes required for AM symbiosis under asymbiotic conditions. We are trying to identify the compounds, establish an efficient AMF culture system with them, and elucidate their functions in AM symbiosis.
