Abstract
Terpenes are natural secondary metabolites with isoprene as the basic structural unit; they are widely found in nature and have potential applications as advanced fuels, pharmaceutical ingredients, and agricultural chemicals. However, traditional methods are inefficient for obtaining terpenes because of complex processes, low yields, and environmental unfriendliness. The unconventional oleaginous yeast Yarrowia lipolytica, with a clear genetic background and complete gene editing tools, has attracted increasing attention for terpenoid synthesis. Here, we review the synthetic biology tools for Y. lipolytica, including promoters, terminators, selection markers, and autonomously replicating sequences. The progress and emerging trends in the metabolic engineering of Y. lipolytica for terpenoid synthesis are further summarized. Finally, potential future research directions are envisioned.
