Abstract Potassium (K+) is a necessary nutrient for plant growth and crop production. The K+ transporter plays crucial roles in the absorption and transport
of K+ in plants. Most K+ transporters in Arabidopsis have been reported, but AtKUP12, which is a member of the KT/KUP/HAK family, has not yet been the subject of relevant in-depth research. In the present study, we demonstrated that
AtKUP12 plays a crucial role in K+ uptake in Arabidopsis under 100 μM lowK+ and 125 mM salt stress conditions. AtKUP12 transcripts were induced by
K+ deficiency and salt stress. We analyzed the K+ uptake of AtKUP12 using… More >
