Ethylene-Induced Vinblastine Accumulation Is Related to Activated Expression of Downstream TIA Pathway Genes in Catharanthus roseus

Figure 3

Expression of genes and accumulation of alkaloids in response to ethephon. (a) Relative expression of DAT, D4H, and T16H genes in Catharanthus roseus. (b) Loading plot of PCA. The first principal component (PC1) was the expression of genes D4H, T16H, and CrPrx1, which were shown as ●. The second principal component (PC2) was the expression of gene DAT, which was shown as ■. (c) Vindoline and catharanthine contents in Catharanthus roseus. The results shown are the means of three replicates; bars represent SE. Different letters indicate significant differences among treatments ().
