Article Title: Compartmentalized sesquiterpenoid biosynthesis and functionalization in the Chlamydomonas reinhardtii plastid

doi: 10.1101/2024.08.21.608953

Figure Lengend Snippet: Sesquiterpene synthases (STPS) and cytochrome P450 enzymes (CYPs) were targeted to the algal chloroplast. Each STPS construct included C-terminal ScErg20 FPPS, while CYPs were co-expressed through plastid targeting and without transmembrane domains. (A) GC-MS chromatograms of dodecane extracts from C. reinhardtii strains expressing plastid localized STPS and CYP combinations, numbers indicate specific compounds identified by MS. (B) Quantitative analysis of sesquiterpenoid production based on GC-FID data. Circles: sum of peak areas for sesquiterpenoids; triangles: sum of peak areas for modified sesquiterpenoids. Data represent mean ± SD (n=12, 4 transformants × 3 biological replicates). (C) Functionalization efficiency (%) of each CYP, calculated as the fraction of functionalized sesquiterpenoids from total sesquiterpenoids. Circles represent individual transformants. Compounds: [1] Aristolene, [2] Aristolochene, [3] Aristolochone, [4] Valencene, [5] Nootkatone, [6] α-Santalene, [7] Bergamotol, [8] Santalol, [9] α-Cadinene, [10] δ-Cadinene, [11] β-Cadinene, [12] Muurolene, [13] Muurolol, [14] τ-Cadinol, [15] α-Guaiene, [16] β-Guaiene, [17] α-Humulene, [18] δ-Guaiene, [19] Alloaromadendrene, [20] α-Guaiol, [21] β-Guaiol, [22] Globulol, [23] Rotundone, [24] Alloaromadendrene oxide. GC-MS/FID data in SI Appendix File S5, Tables S3, and Fig. S6–S7.

Article Snippet: For quantification, we used calibration curves (1 – 500 μM) of purified standards in dodecane or FCs: δ-guaiene, patchoulol, α-santalene, valerianol, α-bisabolol, valencene, and cedrene (Toronto Research Chemicals, Canada) ( SI Appendix, Fig. S5 ).

Figure Lengend Snippet: GC-MS/FID analysis of dodecane overlay samples for sesquiterpenoid species accumulated by C. reinhardtii expressing different STPSs (B02, B03, B06, B08, B09) and corresponding cytochrome P450s (CYP02, CYP05, CYP09, CYP10, CYP12) when cultivated with three carbon source conditions: CO₂, acetate, or CO₂+acetate. Black dots represent sesquiterpenoid compounds; black triangles indicate functionalized derivatives. Relative abundance plots quantify production levels under each condition. (A) Aristolochene synthase (B02) + CYP02; (B) Valencene synthase (B03) + CYP05; (C) Santalene synthase (B06) + CYP09; (D) Cadinol synthase (B08) + CYP10; (E) Guaiene synthase (B09) + CYP12. For each panel, chromatograms (left) show product retention times; bar graphs (right) depict relative abundance. GC-MS/FID data in SI Appendix File S6, Tables S6–S8.
