produces the valuable medicinal component， artemisinin， which is a sesquiterpene lactone widely used in malaria treatment. AaORA， a homolog of CrORCA3， which is involved in activating terpenoid indole alkaloid biosynthesis in ， is a jasmonate (JA)-responsive and trichome-specific APETALA2/ETHYLENE-RESPONSE FACTOR that plays a pivotal role in artemisinin biosynthesis. However， the JA signaling mechanism underlying AaORA-mediated artemisinin biosynthesis remains enigmatic. Here， we report that AaORA forms a transcriptional activator complex with AaTCP14 (TEOSINTE BRANCHED 1/CYCLOIDEA/PROLIFERATING CELL FACTOR 14)， which is also predominantly expressed in trichomes. AaORA and AaTCP14 synergistically bind to and activate the promoters of two genes， () and ()， both of which encode enzymes vital for artemisinin biosynthesis. AaJAZ8， a repressor of the JA signaling pathway， interacts with both AaTCP14 and AaORA and represses the ability of the AaTCP14-AaORA complex to activate the promoter. JA treatment induces AaJAZ8 degradation， allowing the AaTCP14-AaORA complex to subsequently activate the expression of ， which is essential for artemisinin biosynthesis. These data suggest that JA activation of the AaTCP14-AaORA complex regulates artemisinin biosynthesis. Together， our findings reveal a novel artemisinin biosynthetic pathway regulatory network and provide new insight into how specialized metabolism is modulated by the JA signaling pathway in plants.
