POTASSIUM NUTRITION IN THE OIL PALM: A MOLECULAR PERSPECTIVE

Author(s): MOHD NAQIUDDIN*; NYUK LING MA** and MEILINA ONG-ABDULLAH*

Potassium (K+) is a major nutrient essential for plant growth and development. Acquisition of this vital element and maintenance of K+ homeostasis are complex processes, facilitated by an array of membrane transporters including carriers and channels. Key mediators of K+ uptake are the K+ Transporters (KT) /K+ Uptake Permease (KUP)/ High Affinity K+ (HAK) family of transporters. The oil palm (Elaeis guineensis), is an agriculturally and economically important crop, but the molecular mechanisms of nutrient acquisition in this plant are poorly understood. Here we report the first molecular characterisation of potassium transporters from KT/KUP/HAK superfamily in the oil palm, named EgKUP3, EgKUP8 and EgKUP11.
