FIGURE 8.

The expression levels of GmSALT3, GmNHX1, GmSOS1, GmNCED3, GmMYB84, GmDREB2, GmWRKY46, and GmRbohB in RNAi, EV, and OE transgenic soybean plants under control, salt, and drought conditions. (A) Transcripts of GmSALT3, GmNHX1, GmSOS1, GmNCED3, GmMYB84, GmDREB2, GmWRKY46, and GmRbohB in EV and OE transgenic lines under control, salt, and drought conditions. (B) Transcript levels of these genes in RNAi and EV transgenic lines under control, salt, and drought conditions. GmCYP2 was used as the internal control and transcripts of GmNFYA13 were normalized to the expression level in EV transgenic soybean plants under control conditions, which was set as 1.0. CTR represents the control condition, and salt and DH represent salt and drought treatment, respectively. For salt treatment, roots were subjected to 500 mM NaCl solution for 1 h; for drought treatment, roots were placed on a plastic plate for 2 h; roots under normal condition were used as the control sample. Data indicate three biological replicates ± SD. Different letters above the columns represent significant differences at P < 0.05.
