The CBL-Interacting Protein Kinase CIPK23 Regulates HAK5-Mediated High-Affinity K⁺ Uptake in Arabidopsis Roots

Plant growth and development requires efficient acquisition of essential elements. Potassium (K⁺) is an important macronutrient present in the soil solution at a wide range of concentrations. Regulation of the K⁺ uptake systems in the roots is essential to secure K⁺ supply. It has been shown in Arab...

Zusammenfassung:	Plant growth and development requires efficient acquisition of essential elements. Potassium (K⁺) is an important macronutrient present in the soil solution at a wide range of concentrations. Regulation of the K⁺ uptake systems in the roots is essential to secure K⁺ supply. It has been shown in Arabidopsis (Arabidopsis thaliana) that when the external K⁺ concentration is very low (
