Fig. 6: Copy number and expression of genes on morphinan biosynthetic pathway.

Correlation of morphinan production with copy number and expression of morphinan biosynthesis genes in three Papaver species. Copy numbers of morphinan biosynthesis pathway genes were shown in a line plot on left. Production levels of thebaine, codeine, and morphine were shown in bubble plots, and the detail numbers were shown in Supplementary Fig. 2. The total expression of all gene copies in the stem was shown in a line plot on right. N_exp normalized expression. Source data are provided as a Source Data file.
