  "abstract": "Introduction: Potassium is critical for potato yield, but low use efficiency dueto improper fertilization limits production.\n\nMethods: Here, we investigated the effects of different potassium applicationrates (0, 120, 180, 240, and 300 kg·hm ² K?O in 2024; and 0, 180, 240, and300 kg·hm ² K ₂ O in 2025) on potato yield and CIPK8 expression over twofield seasons.\n\nResults: Yield peaked at 240 kg·hm ² (K240), increasing by 23–29% over thecontrol. CIPK8 gene and protein expression followed a unimodal pattern,peaking at 90 days after planting (DAP; tuber bulking stage), with K240inducing >50% higher expression than K0 and significantly higher expressionthan K300. Fluorescence in situ hybridization detected CIPK8 sequences inthe nucleus, while immunofluorescence detected CIPK8 protein in thenucleus, cytoplasm, and membrane.\n\nDiscussion: Our results suggest that K240 is associated with the highestCIPK8 expression and potato yield, suggesting CIPK8 as a potential candidateinvolved in potassium uptake regulation. However, further functionalvalidation is needed to establish a causal relationship. This study provides amolecular basis for efficient potassium management in potato.",
