Effects of AtFC1 overexpression on Na and K accumulation. Three week-old wild type, fc1 mutant and over-expression transgenic plants were treated with 200 mM NaCl for 3 d. Sodium (A,C) and potassium (B,D) contents in shoots and roots were quantified. K+/Na+ ratio in shoots and roots of the 35 S::AtFC1 transgenic lines and wild type after treatment with 0 (E) or 200 mM NaCl (F) for 3 d. Vertical bars represent mean values ± SE. Asterisk indicates the significant difference between fc1/35 S::AtFC1 and WT plants (p < 0.05).
