WebIt has been shown in Arabidopsis (Arabidopsis thaliana) that when the external K+ concentration is very low (,10 mM), K+ nutrition depends exclusively on the high-affinity K+ transporter5 (HAK5). Low-K+-induced transcriptional activation of the gene encoding HAK5 has been previously reported. High Affinity K transporter HAK5 is a transport protein found on the cell surface membrane of plants under conditions of potassium deprivation. It is believed to act as a symporter for protons and the potassium ion, K . Firstly discovered in barley, receiving the name of HvHAK1, it was soon after identified in the model plant Arabidopsis thaliana and named HAK5. These transporters belongs to t…
