Figure 3. Salt tolerance of AtRDUF overexpression plants and mutants.

Figure 3

(A) WT, atrduf1atrduf2, atrduf1, RDUF1-L1 (Line 1 of 35S::AtRDUF1 transgenic plants), RDUF1-L2 and RDUF1-L3 seedlings with or without salt treatment. 3-day-old seedlings were transferred to 1/2 MS medium containing 0, 110, 120 or 150 mM NaCl, and vertically cultured for 6 days. Bars represent 1 cm. (B) Soil-grown plants under salt treatment. 2-week-old soil-grown plants were treated with 200 mM NaCl for 15 days. (C) Germination of seeds at 10 days after imbibition on medium supplemented with 0, 200, or 250 mM NaCl, respectively. (D-F) Primary root length (D), survival rates (E) and germination rates (F) of materials under the conditions described in (A), (B), and (C), respectively. Data are presented as means ± SD. Asterisks indicate significance (*, P<0.05 versus WT control).
