Figure 8

The relative expression of 24 SiARFs analyzed using real-time quantitative PCR under (a) PEG stress treatment and (b) salinity stress treatment after 0 h, 1 h, 3 h, 6 h, 12 h, and 24 h. All the experimental results were based on three biologic replicates. Error bars imply ±SD for three biological replicates. Different letters indicate significant differences ().
