From: Cell-specific expression of tryptophan decarboxylase and 10-hydroxygeraniol oxidoreductase, key genes involved in camptothecin biosynthesis in Camptotheca acuminata Decne (Nyssaceae)

Figure 2

CPT concentration in the shoot apex and in the first 4 leaves of plantlets and mature plants of Camptotheca acuminata , and the effect of drought-stress (D-S) on CPT production. Each value represents the means of three independent determinations; the vertical lines and different letters above the bars indicate standard errors (SE) and statistically significant differences (P ≤ 0.05) between concentrations.
