Evolution‐Inspired Engineering of Diterpene Biosynthesis via Chloroplast Genome Modification
Plant Biotechnology Journal, Volume 24, Issue 10, Page 5510-5525, October 2026.ABSTRACT Terpenes constitute the largest and most structurally diverse class of plant secondary metabolites, with critical roles in plant‐environment interactions and broad industrial applications. Although nuclear genome engineering of terpene pathways has been extensively explored, chloroplast genome engineering remains largely undeveloped, with most
