Nitrate is the main source of nitrogen for plant growth and development under aerobic conditions, which serves as an important nutrient and signaling molecule, understanding the nitrate signaling pathway is important for agricultural production. Auxin response factors (ARFs) are associated with nitrate signaling, but their underlying mechanism is less known in apples. In this study, it was found that MdARF18 can be expressed as a transcription factor activated by nitrate, and inhibited the uptake of nitrate in apples. Then, MdARF18 was found to bind directly to the TGTCTT site of the MdNRT1.1 promoter and significantly reduced its expression. In conclusion, MdARF18 regulates nitrate uptake in plants by mediating the expression of MdNRT1.1, providing insight into the mechanism by which MdARF18 regulates nitrate uptake and utilization in apples.
