Research Progress on Mechanism of Low Phosphorus Tolerance in Crops
Phosphorus is one of the essential nutrients for crop growth and development,and plays an important role in the life process of crops.Crops have formed a series of low phosphorus adaptation mechanisms in the long-term evolution process,mainly involving the activation, absorption,transport of soil phosphorus and the recycling and reuse of phosphorus in crop tissues.In this paper,the latest research progress on the mechanism of low phosphorus tolerance of crops was reviewed from four aspects:root morphology,root exudates,symbiotic system with mi-croorganisms,and molecular mechanism under low phosphorus stress,in order to provide reference for crop cultivation regulation and improve-ment and breeding of low phosphorus tolerant crop varieties.
