GmNHX1 positively regulates plant salt tolerance. Transcription Level of GmNHX1 under salt stress in Soybean was detected by RT-qPCR, ACTIN gene was used as a reference gene. The data shows the mean ± S.E. of triplicate experiments. Columns with different letters indicate significant differences at P < 0.05 (a). The silencing efficiency of GmNHX1 in silenced plants using VIGS were detected by RT-qPCR, using ACTIN as reference gene (b). Phenotype of TRV- VIGS plants under 200 mM NaCl solution treatment for 24 h (c)
