Transgenic oilseeds as sustainable source of nutritionally relevant C20 and C22 polyunsaturated fatty acids?

High‐value oils from plants

“…However, from the long-term perspective, this solution is hampered by the steady decrease in global fish populations (Sargent and Tacon, 1999) in combination with various problems associated with commercial fish farming (Naylor et al, 2000). Generation of plants that produce high amounts of 'fish oil'-type fatty acids, therefore, would be highly desirable for sustainable production of these important fatty acids (Abbadi et al, 2001;Ursin, 2003).…”

Microalgal Biotechnology: Prospects and Applications

“…Some of the environmental conditions include heterotrophic, photoautotrophic and nitrogen deprivation or stimulation. Although some microalgae species are cultivated as sources of these fatty acids, transgenic algae engineered to produce EPA, like transgenic oilseed crops, could provide an alternative sustainable source of oil for human consumption [18]. However, the possibility for deploying transgenic organisms nutritionally enhancedwith EPA is currently limited by continued consumer antipathy to transgenic food products.…”

n -3 Oil sources for use in aquaculture – alternatives to the unsustainable harvest of wild fish

“…However, the requirement for coordinate expression and activity of five or more new enzymes encoded by genes from possibly diverse sources has made this goal difficult to achieve and only low yields have generally been obtained (139,141,142) .…”
