GbAACT and GbMVK expression level (A,B) and total terpene trilactone (TTL) content (C) changes in ginkgo by salicylic acid (SA) and methyl jasmonate (MeJA). The expression levels were normalized to the house-keeping gene GAPDH (glyceraldehyde-3-phospate dehydrogenase). Data from qRT-PCR were analyzed as expression ratios relative to the level of control (CK), and are shown as the mean ± SD of triplicate assays. Means with different letters from each time of post-treatments are significantly different at p < 0.05 by one-way ANOVA, with Tukey’s honestly significant difference test.
