摘　　要：利用和挖掘作物自身磷高营养效率的能力,以改良作物磷营养性状,已成为植物磷素营养研究的重点和热点。论述了低磷胁迫下植物根系形态、根系分泌物以及磷的跨膜运输和体内转运等方面的适应性变化,总结了目前与磷高效营养性状有关的基因定位和克隆的研究进展,进而揭示出植物低磷胁迫忍耐机理。Studies on physiological adaptability of root morphology, root excretion, transportation of P across plasma membrane and P translocation of plants under phosphorus deficiency stress were summarized. Researches on the basis of molecular biology related to excavation of plant＇s phosphorus high nutrition efficiency were also discussed. It would be helpful for understanding the adaptation mechanisms of plants to phosphorus deficiency stress.
