Abstract Background Improving plant potassium uptake efficiency is of great significance for agricultural production. Auxin, as a key hormone, promotes root growth activity and enhances the plant's ability to absorb accumulate mineral nutrients. To investigate role auxin in mechanisms under low-potassium stress, this study utilized tobacco model conducted hydroponic experiments. Results Low-potassium stress significantly impaired development plants. Under these conditions, exogenous IAA enhanced increased uptake, while NPA inhibited adversely affected absorption retention. Transcriptome sequencing conditions identified 8,381 differentially expressed genes (DEGs) between two treatment groups, which were primarily enriched pathways related photosynthesis-antenna proteins, photosynthesis, hormone signal transduction, MAPK signaling pathway. Analysis DEGs associated with signaling, ion channels, transporters, transcription factors revealed several involved response including KUP6, IAA14, ARF16, PIN1, SKOR, NPF7.3, AP2/ERF. Notably, KUP6 was upregulated following downregulated NPA, indicating that transporter gene plays crucial auxin-mediated alleviation tobacco, likely linked endogenous levels Conclusions Our research reveals deficiency impairs critical mitigating stress. This highlights auxin’s regulatory function enhancing offering insights into molecular

With the increasing number of patients with chronic kidney disease (CKD) and improved recognition nutritional therapy, research on low-potassium (LK) fruits vegetables for CKD has gained global attention. Despite its already commercial availability primarily in Japan, public awareness remains limited, cultivation methods lack a comprehensive strategy. This review offers an extensive examination developmental significance, current techniques, existing limitations functional LK objective providing guidance inspiration their exploitation. Additionally, this investigates various factors influencing K content, including varieties, temperature, light, exogenous substances, harvest time, parts, focus optimizing production to enhance potassium utilization efficiency (KUE) decrease content plants. Finally, outlines shortcomings prospects vegetables, emphasizing importance interdisciplinary (in agriculture technology, medicine, business) future development field.
