GmNHX1positively regulates plant salt tolerance. Transcription Level ofGmNHX1under salt stress in Soybean was detected by RT-qPCR,ACTINgene was used as a reference gene. The data shows the mean ± S.E. of triplicate experiments. Columns with different letters indicate significant differences atP< 0.05 (a). The silencing efficiency ofGmNHX1in silenced plants using VIGS were detected by RT-qPCR, usingACTINas reference gene (b).
