Phosphorus (P) is an essential macronutrient for plant growth. The roots are the main organ for nutrient and water absorption in plants, and they adapt to low-P soils by altering their architecture for enhancing absorption of inorganic phosphate (Pi). This review summarizes the physiological and molecular mechanisms underlying the developmental responses of roots to Pi starvation, including the primary root, lateral root, root hair, and root growth angle, in the dicot model plant and the monocot model plant rice (). The importance of different root traits and genes for breeding P-efficient roots in rice varieties for Pi-deficient soils are also discussed, which we hope will benefit the genetic improvement of Pi uptake, Pi-use efficiency, and crop yields.
磷（P）是植物生长所必需的大量营养素。根是植物吸收养分和水分的主要器官，它们通过改变其结构来增强对无机磷酸盐（Pi）的吸收，从而适应低磷土壤。本综述总结了双子叶模式植物和单子叶模式植物水稻中根对磷饥饿的发育响应的生理和分子机制（）。还讨论了不同根特性和基因在培育对缺磷土壤具有高效吸收磷能力的水稻品种中的重要性，我们希望这将有助于提高磷吸收、磷利用效率和作物产量的遗传改良。
