WT and OE represent wild-type and ZmMYB59 transgenic lines, respectively. GA, CTK, IAA, ABA represent gibberellin, cytokinin, indole-3-acetic acid, abscisic acid, respectively. Means with standard deviations that do not followed by the same lower case letter between OE and WT lines significantly differ by ANOVA analysis at 5% level of significance. There are three replicates for each index, and 8 tobacco seedlings or 12 rice seedlings for each replicate.
