The present technology provides transcription factors for modifying plant metabolism and nucleic acid molecules that encode such transcription factors. Also provided are methods of using these nucleic acids to modulate alkaloid production in plants and for producing plants and cells having altered alkaloid content.本發明技術提供用於修飾植物代謝之轉錄因子,及編碼該等轉錄因子之核酸分子。亦提供使用該等核酸以調節植物中之生物鹼產生,及產生具有改變之生物鹼含量之植物及細胞的方法。
