<i>nhx5 nhx6</i> is sensitive to low K⁺ treatment.

<p>(A) Seedling growth under low K⁺ treatment. (B) Expression of <i>AtNHX5</i> and <i>AtNHX6</i> recovered <i>nhx5 nhx6</i> growth under low K⁺ treatment. (C) Root growth was measured 7 days after the seedlings were grown on the media containing various levels of KCl. Three independent experiments were performed, and about 10 seeds were counted for each experiment. Data are means SD. (D) Root growth was measured 10 days after the seedlings were grown on the media containing 0.01mM KCl. Three independent experiments were performed, and about 10 seeds were counted for each experiment. Data are means SD. (E) K⁺ content in seedlings. Three independent experiments were performed, and about 10 seeds were counted for each experiment. Data are means SD.
