Relative expression levels of genes in secondary metabolite biosynthetic pathways as determined by qRT-PCR. Relative expression levels are presented as the mean of three replicates ± standard error. HY: Zheng58 × sub-CSSL16; CK: Zheng58 × lx9801. * and **Indicate significant differences at P < 0.05 and P < 0.01, respectively, as determined by a one-way ANOVA with Student’s t-test.
