The structure and growth of the root system of rice directly affect its ability to absorb water and nutrients. In adverse environments such as drought and high salt content, the role of the root system becomes particularly significant. This study mainly collated the key genes and regulatory relationships related to the formation of the crown roots, lateral roots, changes in root length, root angles, and root hair development. By combining transcriptome, epigenetic, and population genetics research results, it analyzed the response characteristics of these root development-related genes under drought and salt stress conditions, and discussed how to utilize important root development genes and their excellent allelic variations to provide references for the improvement of rice root traits, genetic breeding, and the enhancement of resource utilization efficiency.
