Na⁺ content of Col-0, Tsu-1, <i>athkt1</i> and <i>hkt1-c1</i>.

<p>(A) Na⁺ content in flowers under normal conditions. (B) Na⁺ content in flowers under salt treatment. Negatively correlated between floral sodium content and seed number under salt stress (<i>Embedded</i>) (C) Na⁺ content in stems under normal conditions. (D) Na⁺ content in stems under salt treatment. (E) Na⁺ content in rosette leaves under normal conditions. (F) Na⁺ content in rosette leaves under salt treatment. Five-week-old plants irrigated without or twice with 100 mM NaCl were used to analyze Na⁺ by ICP-MS. Data represented with mean ± SE, <i>n</i> = 12, and significant differences were determined by ANOVA.
