Comparison of Na⁺ and K⁺ accumulation in shoots and roots between WT, PutHKT2;1, and OsHKT2;1 over-expression lines. Seven-day-old WT and transgenic seedlings grown on MS were transferred to minimal-medium supplemented with the indicated salts. Seedlings were grown vertically for 14 additional days before being harvested. For each treatment, the ion content was determined from a pool of 15 plants. Results are expressed as means ±SE (n=3). Asterisks indicate a significant difference from the WT (P <0.05) by Student's t test.
