Punicic acid (PuA) is a conjugated linolenic acid (C18:3Δ 9c,11t,13c ) with a wide range of nutraceutic effects with the potential to reduce the incidence of a number of health disorders including diabetes, obesity, and cancer. It is the main component of seed oil from Punica granatum and Trichosanthes kirilowii. Previously, production of relatively high levels of this unusual fatty acid in the seed oil of transgenic Arabidopsis thaliana plant was accomplished by the use of A. thaliana fad3/fae1 mutant high in linoleic acid (18:2∆ 9c,12c ) and by co-expression of P. granatum FATTY ACID CONJUGASE (PgFADX) with Δ12-DESATURASE (FAD2). In the current study, P. granatum cDNAs governing PuA production were introduced into the yeast Schizosaccharomyces pombe. Expression of PgFADX alone resulted in production of PuA at the level of 19.6% of total fatty acids. Co-expression PgFADX with PgFAD2, however, further enhanced PuA content to 25.1% of total fatty acids, the highest level reported to date for heterologous expression. Therefore, microbial systems can be considered as a potential alternative to plant sources for a source of PuA for nutraceutic applications.
