Rice (Oryza sativa) is a globally important cereal crop, and the rational application of fertilizers is necessary agricultural practice to ensure its sustainable and stable yield. Phosphorus is one of the essential nutrients for rice, primarily absorbed through the rice roots. Since rice is mostly grown in flooded conditions, the root surface of rice generally forms iron plaques rich in iron oxides, which play a crucial role in the migration of inorganic phosphorus in the rhizosphere of rice. This paper reviews the impact of biotic and abiotic factors on the formation of iron plaques in rice and discusses the effect of iron plaques on the absorption and transport of phosphorus in plant nutrition. Furthermore, we discuss the prospects of future research on iron plaques, aiming to provide clues for our further understanding of the interactions between iron and phosphorus in the rhizosphere of rice.
