Effects of overexpression of HtNHX1 and HtNHX2 on rice growth, harvest index grown in the soil with different amount of additive salts (NaCl). Two‐week‐old seedlings were acclimated to the soil containing 0.1% (1‐g/kg soil) NaCl for 1 week before being transplanted to the pot filled with 40 kg of soil which had been fertilized and mixture with indicated extra amount of salts for 2 weeks. Control: no additive NaCl was provided into the fertile soil (see Table S2); 0.13% and 0.18% salts: adding 1.3 and 1.8 g NaCl per kg soil in the pot. WT: cv. Nipponbare; X1‐1, 1‐2: two T2 individual transgenic lines of expressing HtNHX1; X2‐1, 2‐2: two 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.
