Here, we show that the NIN\u2010LIKE PROTEIN7 (NLP7) transcription factor, which mediates nitrate signaling, plays a crucial role in promoting K acquisition in Arabidopsis. K\n                    <jats:sup>+<\/jats:sup>\n                    uptake activity was reduced in the\n                    <jats:italic>nlp7<\/jats:italic>\n                    mutant and\n                    <jats:italic>nlp6nlp7<\/jats:italic>\n                    double mutant but enhanced in the\n                    <jats:italic>NLP7<\/jats:italic>\n                    \u2010overexpressing line. Consistently, these mutants were hypersensitive to K deficiency, whereas the\n                    <jats:italic>NLP7<\/jats:italic>\n                    \u2010overexpressing line displayed increased tolerance. Transcriptome analysis of the\n                    <jats:italic>nlp6nlp7<\/jats:italic>\n                    mutant suggested that NLP7 activates several critical K\u2010related genes, including\n                    <jats:italic>HAK5<\/jats:italic>\n                    , a transporter gene essential for K\n                    <jats:sup>+<\/jats:sup>\n                    uptake from soil, and\n                    <jats:italic>SKOR<\/jats:italic>\n                    , a channel gene critical for root\u2010to\u2010shoot transport of K\n                    <jats:sup>+<\/jats:sup>\n                    . Using co\u2010transfection assays, gel electrophoresis mobility shift assays, and chromatin immunoprecipitation assays, we demonstrate that NLP7 directly interacts with and activates the promoters of these two genes. Furthermore, the enhanced K\n                    <jats:sup>+<\/jats:sup>\n                    uptake and improved K deficiency responses driven by\n                    <jats:italic>NLP7<\/jats:italic>\n                    overexpression were mitigated in the\n                    <jats:italic>hak5<\/jats:italic>\n                    and\n                    <jats:italic>skor<\/jats:italic>\n                    mutants, demonstrating the significant physiological role of NLP7\u2010induced activation of these genes. Although\n                    <jats:italic>HAK5<\/jats:italic>\n                    and\n                    <jats:italic>SKOR<\/jats:italic>\n                    responded differently to K deficiency, both genes were activated similarly by NLP7 under K\u2010sufficient and K\u2010deficient conditions. Together, these findings suggest that K deficiency\u2010induced regulation and nitrate\u2010responsive regulation operate through independent transcriptional mechanisms but collaborate to ensure appropriate K acquisition under diverse N and K conditions, especially when K availability is limiting.\n
