Stepwise engineering to produce high yields of very long-chain polyunsaturated fatty acids in plants

Article Abstract:

A study reports the transgenic production of significant amounts of arachidonic acid (AA) and eicosapentaenoic acid (EPA) in Brassica juncea seeds through a stepwise metabolic engineering strategy. A series of transformations with increasing numbers of transgenes are used to demonstrate the incremental production of very long chain polyunsaturated fatty acids (VLCPUFAs), achieving AA levels of upto 25% and EPA levels of upto 15% of total seed fatty acids.

Engineering the essence of plants

Article Abstract:

Researchers have described an approach for engineering plants that produce elevated levels of commercially relevant terpenoids. The efficacy of the approach is demonstrated with two sesquiterpenes and a monoterpene, suggesting that the strategy can be generally applied to produce complex plant metabolites, many of which cannot be synthesized chemically or derived from endangered species in threatened ecosystems.
