Organism | Comment | Expression |
---|---|---|
Artemisia annua | transcription factor protein glandular trichome-specific WRKY 1, i.e. AaGSW1, promotes artemisinin biosynthesis in Artemisia annua by inducing CYP71AV1 expression. AaGSW1 positively regulates CYP71AV1 and AaORA expression by directly binding to the W-box motifs in their promoters. Overexpression of AaGSW1 in Artemisia annua (via Agrobacterium tumefaciens transformation method) significantly improves artemisinin and dihydroartemisinic acid contents. AaGSW1 can be directly regulated by AaMYC2 and AabZIP1, which are positive regulators of jasmonate- and abscisic acid-mediated artemisinin biosynthetic pathways, respectively. AaGSW1 binds to the W-box in the CYP71AV1 promoter in vitro and activates the transcription of CYP71AV1 in vivo.
