摘　　要：Drought is a significant environmental challenge that hinders global crop production.Over the past decade,drought-related losses in crop yields have amounted to around$30 billion.Upland rice(UR)is domesticated as a unique ecotype with high drought-aerobic adaptation under long-term natural and artificial selection under aerobic and dry soil conditions.In contrast,lowland rice(LR)is typically grown in flooded paddy fields.There are distinct genetic differences between upland and LR when it comes to drought resistance and productivity traits(Xia et al.,2022).In contrast,water-saving and drought-resistant rice varieties have been successfully developed through conventional breeding of elite rice by harnessing genetic resources from UR.However,the genetic basis of aerobic drought-adaptive traits remains unclear,which limits the potential use of genetic variations in breeding efforts.Recently,Han et al.(2024)elucidated the genetic mechanisms underlying root development and drought resistance in UR accession through the OsNAC41-RoLe1-OsAGAP module,providing valuable insights for breeding drought-resistance rice(Figure 1A).
