From: Effect of IAA on coumarins synthesis in Angelica dahurica under soil compactness stress

A.Expression patterns of genes involved in coumarins biosynthesis. B.Relative expression of coumarins synthesis genes in A. dahurica taproots was determined by qRT-PCR under different concentrations of IAA treatment. CK(control treatment, 0 mg/L), LT(low treatment, 0.3 mg/L ),MT (medium treatment, 0.6 mg/L), HT(high treatment, 0.9 mg/L) and ST(super-high treatment, 1.2 mg/L) represent treatment groups with different concentrations of IAA, respectively.Data are the mean values (n = 3). Letters represent significant differences between treatments (p < 0.05).
