Figure 2. Relative expression of aquaporin genes in leaves of plants exposed to a drying-rewatering cycle.

Figure 2

Gene expression was measured in leaves of well-watered control plants (C), drought-stressed plants (D), and 3 h after drought-stressed plants were rewatered (RW). The geometric mean of the expression levels of four reference genes (ACT2, CYC063, TIP41-like, UBQ7) was used to normalize the results. Asterisks denote significant differences in expression level compared to control levels (one-way ANOVA, followed by Bonferroni’s post test, *P≤0.05; **P≤0.01***P≤0.001). Data are means ± SE of three biological replicates.
