Effects of different potassium application rates on potato yield and the expression of CIPK8, a candidate gene involved in potassium uptake
Year: 2026
Type: article
Abstract: Introduction: Potassium is critical for potato yield, but low use efficiency dueto improper fertilization limits production. Methods: O in 2025) on potato yield and CIPK8 expression over twofield seasons. Results: (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. Discussion: 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.
