Fig. 3. Expression profiles of SmMYB1 and genes involved in the phenolic acid biosynthesis pathway in response to treatment with MeJA.

A Expression patterns of SmMYB1 in different tissues. The fold changes of the relative gene expression level in all the other tissues are normalized to the expression level in the calyx tissue. B Effect of elicitors (yeast extract, YE; abscisic acid, ABA; salicylic acid, SA; methyl jasmonate, MeJA; gibberellic acid, GA₃; ethylene, Eth) on SmMYB1 expression. C Expression profiles of genes in the phenolic acid biosynthesis pathway after treatment with MeJA. The fold changes in the relative gene expression level were all normalized to the control expression without induction at the 0 h time point in B and C. The error bars indicate the standard errors of the means. The asterisks indicate significant differences between the calyx versus the other tissues in A, between the treatment versus the control in B, and according to C t-tests at two different significance levels (**P < 0.01; *P < 0.05). The experiment was replicated three times
