H2O2 mediated GA biosynthesis and ABA suppressed GA biosynthesis. (a) The germination of cyp707a2 and the CYP707A2 overexpression line in freshly harvested seeds under different treatments. (b) Change in the transcript levels of GA3ox GA biosynthesis genes under different treatments in cyp707a2 and the CYP707A2 overexpression line after 24 h imbibition. (c) Change in the transcript levels of GA-regulated genes XTH5 and EXP2 under different treatments in cyp707a2 and the CYP707A2 overexpression line after 24 h imbibition. H2O2 (10 mM), SNP (200 μM), ABA (0.5 μM), and GA (10 μM) were used for these experiments. Values are the means±SE (n=3 for a–d). An ANOVA test followed by a rank test was performed. Different letters are used to indicate means that are significantly different (P <0.05)
