摘　　要：Highlights The water use efficiency of the drought-resistant variety MT3 was found to be correlated with stomatal density.EPFs enhance water use efficiency and drought tolerance by regulating stomatal density in foxtail millet.Drought(D)causedbyglobalwarmingisseverely affecting crop growth and agricultural production (Gupta etal. 2020).Stomata provide an important window for photosynthesis and water transpiration, and stomatal densityiscloselyrelatedtothedroughtresponse(Herrmann and Torii 2021).Foxtail millet (Setaria italica)isan important drought tolerant crop that plays an important role in ensuring food and nutritional security(Muthamilarasan and Prasad 2017).Unlike in other crops, the drought-resistance mechanism of foxtail millet is not fully understood, with only SiDPY1, SiYTH1, and SiMYBS3 currently identified and characterized (Liu et al.2023;Luo et al. 2023;Zhao et al. 2023).Therefore, the drought resistance mechanism remains unclear.
