Summary

Potassium acetate is a soluble source of potassium that can improve plant growth and stress tolerance. Although potassium is a recognized necessary macronutrient, the precise physiological and molecular mechanisms associated with its acetate form in plants are inadequately understood. However, limited information exists on the impact of potassium acetate on critical stress-responsive genomic pathways, particularly those governed by Dehydration-Responsive Element-Binding (DREB) transcription factors, which are essential for abiotic stress tolerance. The significant information gap regarding potassium acetate-induced stress responses was resolved via integrated physiological and molecular investigations: Optimal potassium acetate concentrations were found to enhance barley growth and stimula
