Figure 4.
Relative expression of NtCER7 under salt stress and in different organs of N. tangutorum. EF1-α and His and EF1-α + His were used as one or two of the most stable reference genes; HSP was used as the least stable reference gene. Different letters indicate significant differences in the expression of the target gene based on three biological replications (P < 0.05). The figures were generated by using OriginPro software (version 2018; https://www.originlab.com/).
