Lupeol production in Phaeodactylum tricornutum transformant lines. GC‐MS analysis of transformant lines AtLUS‐6 (yellow) and LjLUS‐25 (red) with the wild type (blue). Lupeol standard in black. 1. Brassicasterol (major sterol in P. tricornutum). 2. Lupeol; 3. 3β, 20‐dihydroxylupane by‐product of AtLUS enzyme only. Additional peaks: a. campesterol; b. unidentified diterpene molecule; *unidentified terpenoid molecules, mass spectra for these peaks with their best database hits are shown in Figure S3.
