Oct 10, 2024 · Arabidopsis K+ transporter HAK5-mediated high-affinity root K+ uptake is regulated by protein kinases CIPK1 and CIPK9. AKT1 and AtHak5 are associated with both uptake and translocation of Potassium in Arabidopsis.

Oct 3, 2024 · Here, the authors show the transport characteristics of Arabidopsis HAK5, unveiling its K+ and pH dependent activation and deactivation kinetics.

Aug 6, 2020 · The high-affinity K+ transporter HAK5 is the major contributor to root K+ uptake from dilute solutions in K+-starved Arabidopsis plants. Its functionality is tightly regulated and its activity is enhanced under K+ starvation by the transcriptional induction of the AtHAK5 gene, and by the activation …

In this study, a gene encoding for a high-affinity potassium transporter (MeHAK5) was isolated from cassava and its function was investigated. Subcellular localization analysis showed that Me HAK5 is a plasma membrane-localized transporter.

High Affinity K+ transporter HAK5 is a transport protein found on the cell surface membrane of plants under conditions of potassium deprivation. [1][2][3] It is believed to act as a symporter for protons and the potassium ion, K +. [4] .

Mar 22, 2021 · Phosphorylation of ARF2 relieves its repression of transcription of the K + transporter gene HAK5 in response to low potassium stress

Jul 27, 2013 · HAK5, an Arabidopsis high-affinity K transporter gene, plays an important role in K uptake. Its expression is up-regulated in response to K deprivation and is rapidly down-regulated when sufficient K levels have been re-established.

Sep 13, 2023 · To better understand the biological functions and expression regulation mechanism of potassium transporter gene GmHAK5 in soybean, the coding sequence (CDS) of GmHAK5 gene was cloned in this study, and its encoding protein had the typical structural features of the HAK/KUP/KT family genes.

arabidopsis thaliana high affinity k+ transporter 5, athak5, hak5, high affinity k+ transporter 5 Description Encodes a protein of the KUP/HAK/KT potassium channel class that is upregulated in the roots by K levels.

Oct 6, 2009 · We found that AtHAK5 is required for K + absorption necessary to sustain plant growth at low K + in the absence as well as in the presence of salinity. Salinity greatly reduced AtHAK5 transcript levels and promoted AtAKT1-mediated K + efflux, resulting in an important impairment of K + nutrition.
