Metabolic Engineering of Terpenoid Biosynthesis in Medicinal Plants: From Genomic Insights to Biotechnological Applications

Le résumé fourni par la source

Terpenoids, vital pharmaceutical compounds, face production challenges due to low yields in native plants and ecological concerns. This review synthesizes recent advances in metabolic engineering strategies implemented across three complementary platforms: native medicinal plants, microbial systems, and heterologous plant hosts. We elucidate how the "Genomic Insights to Biotechnological Applications" paradigm, empowered by multi-omics technologies such as genomics, transcriptomics, metabolomics, etc., drives research advancements. These technologies facilitate the identification of key biosynthetic genes and regulatory networks. CRISPR-based tools, enzyme engineering, and subcellular targeting are highlighted as transformative strategies. Significant yield improvements have been demonstrated, with artemisinin and paclitaxel precursors showing considerable increases in production through strategic co-expression and optimization techniques. Persistent challenges such as metabolic flux balancing, cytotoxicity, and scale-up economics are discussed alongside emerging solutions including machine learning and photoautotrophic chassis. We conclude by outlining a roadmap for industrial translation that emphasizes the critical integration of systems biology and synthetic biology approaches to accelerate the transition of terpenoid biomanufacturing from discovery to commercial scale.
