Welcome to HAK !

Potassium is one of the essential nutrients for plant growth and development, and potassium is widely distributed in various tissues as the second most abundant cation in plants. Potassium plays an important role in maintaining the cytosolic pH, cell turgor, cell elongation, enzyme activation, osmotic adjustment, some physiological processes and radiocesium toxicity reduction in soil. Potassium transporters can be divided into four families: the KT (K+ transporter)/HAK (high-affinity K+)/KUP (K+ uptake) family, Trk/Ktr/HKT family, KEA (K+ efflux antiporter) family, and CHX (cation/hydrogen exchanger) family. The HAK/KUP/KT family contains high-affinity K+ transport carriers and is mainly responsible for the absorption and transport of K+ by plants.
