Salt-stress responses of soil-grown EpHKT1;1- and EpHKT1;2-overexpressing plants compared with AtHKT1-overexpressing plants. (A) Seeds were germinated on 1XMS medium in a growth chamber under long-day conditions (16 h light, 8 h dark). One-week-old seedlings were then transferred to soil and grown for 2 more weeks. Photographs were taken before salt treatment. (B) Fresh weight of plants shown in A. (C) Two-weeks-old plants, as shown in A, were treated with 300 mM NaCl twice a week for 2 weeks. Photographs were taken at the end of salt treatment. (D) Fresh weight of plants shown in C. Error bars represent SE. Significant differences were determined by Student’s t-test (∗P < 0.001 and ∗∗P < 0.01) compared with Col-gl1 under salt treatment.
