Figure 3.

Relative gene expression of FPS (A), β-AS (B), CYP88D6 (C), CYP72A154 (D), LUS (E), and CHS (F) in roots of liquorice plants under different treatments (□ non-inoculation; ■ AM inoculation). US and S represent unsterilized and sterilization treatment, respectively. Data are presented as means ± SE (n = 4). Treatment effects (S: Sterilization; I: Inoculation) are tested by two-way ANOVA and are shown as p values in the figure. Different lowercase letters above the columns indicate a significant difference between corresponding treatments at p < 0.05 by Tukey’s HSD test.
