The Dynamic Changes in Biosynthesis and Spatiotemporal Distribution of Phytohormones Under Jasmonic Acid Treatment Provide Insights into Hormonal Regulation in <i>Sinopodophyllum hexandrum</i>.

ABSTRACT: Sinopodophyllum hexandrum (Royle) Ying, the only species of Sinopodophyllum in Berberidaceae, is an endangered traditional Tibetan medicine. The harsh plateau growth environment makes S. hexandrum tough to breed and meet the global demand for clinical medications such as podophyllotoxin (PTOX) and etoposide. Jasmonic acid (JA) is acknowledged as a key phytohormone that modulates stress responses by activating defense mechanisms and promoting the production of specialized metabolites, which offers valuable insights for developing varieties that are more resilient to stress or yield higher amounts of secondary metabolites. In this study, JA treatment was used as a simulated source of stress to investigate the spatiotemporal changes in phytohormones, such as JA, cis
