RESUMO

The functional expression in yeast of the Arabidopsis thaliana FAD2 gene, encoding the extraplastidial oleate desaturase (1-acyl-2-oleoyl-sn-glycero-3-phosphocholine delta 12-desaturase) is reported. Dienoic fatty acids constituted up to 11% (w/w) of the total fatty acids in transformed Saccharomyces cerevisiae cells and were confirmed to be linoleic acid and delta 9, delta 12-hexadecadienoic acid by gas chromatography-mass spectrometry.
