Abstract:

The aim is to understand the mechanism of phosphorus uptake and transport in plants under the effect of Arbuscular mycorrhizal (AM) fungi. We summarize the latest research results about AM fungi promoting effect on improving phosphorus nutrition situation (such as phosphate transporter, phosphatase gene, etc.) in plant, emphatically analyze the mycorrhizal absorption pathway of AM fungi, and review the utilization mechanism of water-soluble inorganic phosphorus, insoluble inorganic phosphorus and organic phosphorus by AM fungi at home and abroad. Finally, we point out some problems still exist in this field and give advices on the future research focus.

Key words: Arbuscular mycorrhizal fungi, plant phosphorus nutrition, phosphate transporters, absorption and transport mechanisms
