Effects of overexpression of HtNHX1 and HtNHX2 on rice growth under different nutrient supply and salt‐stress condition. The rice was grown for 21 days in the solution before the sampling. (a, c, d) IRRI solution with full supply of nutrients (see Materials and methods); (b, e, f) Full nutrient solution + 100 mm NaCl. WT: cv. Nipponbare; X1‐1, 1‐2, 1‐3, 1‐4 and 1‐5: five T2 individual transgenic lines of expressing HtNHX1; X2‐1, 2‐2, 2‐3, 2‐4 and 2‐5: five T2 individual transgenic lines of expressing HtNHX2. Different letter(s) on the column indicates the significant difference at probability at 5%. ns: no significant difference.
