Research Advances in the Function of the High-affinity K+ Transporter (HKT) Proteins and Plant Salt Tolerance

doi:10.11983/CBB17230

Abstract

Abstract: Soil salinity affects the growth of plant species, which can cause osmotic stress and ionic toxicity in the plants. Therefore, it is crucial to maintain Na⁺/K⁺ homeostasis at the cellular and whole plant levels for plant salt tolerance. The high-affinity potassium transporters (HKTs) were found to have a ability to transport and distribute Na⁺and K⁺ in plants. Here we summarize the advance about the structure and function of the HKT proteins from glycophytes and halophytes. Further discussion is directed to genetically modified and artificially designed transport proteins for genetic engineering of salt-tolerant plants.

Key words: HKT, ion homeostasis, salt tolerance, transport protein
