-Expression levels of these biosynthetic genes were analyzed in various tissues (leaf, root, cone, and bark) and after jasmonate treatment. Jasmonate, a known elicitor of secondary metabolism, significantly upregulated nearly all paclitaxel biosynthesis genes, except for GGPPS and CoA Ligase. This highlights the role of external stimuli in boosting paclitaxel production and points to potential strategies for enhancing yield through controlled jasmonate induction.
