Fig. 1From: Characterization of fatty acid desaturases reveals stress-induced synthesis of C18 unsaturated fatty acids enriched in triacylglycerol in the oleaginous alga Chromochloris zofingiensisGC–MS chromatography of fatty acids from S. cerevisiae expressing the empty vector pYES2 and CzFAD genes. a S. cerevisiae transformant with pYES2, CzFAD2, CzFAD6A or CzFAD6B. b S. cerevisiae transformant with pYES2, CzFAD7A or CzFAD7B supplemented with FFA C18:2Δ9,12 or C18:3Δ6,9,12. c S. cerevisiae transformant with pYES2, CzFAD5A, CzFAD5B or CzFAD5C. d S. cerevisiae transformant with pYES2, CzFAD3A or CzFAD3B supplemented with FFA C18:2Δ9,12 or C18:3Δ9,12,15. e S. cerevisiae transformant with pYES2 or CzFAD4. Newly synthesized and added fatty acids are designated in red and blue, respectively. C17:0 was added as the internal controlBack to article page
