The lack ofphosphorus in rice is one ofthe major limited factors torice yield.Four aspects were summarized in the paper,i.e.,the existingforms ofphosphorus in soil and utilization efficiencyt,he characteristic of low phosphorus tolerance of rice varietiest,he screening of rice varieties tolerant to low phosphorus and molecular marker ofits gene,genetic transformation,gene clone.Moreovert,he future trends ofresearches on low phosphorus stress were predicted.This would supplysome theoretical base for screeningrice varieties with high efficiencyofphosphorususageandtoleranttolowphosphorusstress.
