qRT-PCR results of the genes related to salinity tolerance among the Cheongcheong and Nagdong lines, as well as the five resistant and five susceptible lines. The relative expression levels of Os03g0741100, Os03g0741600, Os03g0741700, Os03g0742900, Os03g0742900-1, and Os03g0742900-2 were analyzed after 140 mM of NaCl stress at 0 h, 1 h, 3 h, 6 h, 12 h, and 24 h. Each time point was compared with 0 h in all genes. The error bars represent the standard error of each mean data (n = 3). The error bars with no asterisks indicate non-significant differences, and those with asterisks indicate a significant difference (* p < 0.05, ** p < 0.01, and *** p < 0.001), according to analysis using two-way ANOVA and the Bonferroni post hoc test.
