摘要:
The present invention relates to compositions and methods for preparing poly-unsaturated long chain fatty acids in plants, plant parts and plant cells,such as leaves, roots, fruits and seeds. Nucleic acid sequences and constructsencoding PKS-like genes required for the poly-unsaturated long chain fattyacid production, including the genes responsible for eicosapentenoic acidproduction of Shewanella putrefaciens and novel genes associated with theproduction of docosahexenoic acid in Vibrio marinus are used to generatetransgenic plants, plant parts and cells which contain and express one or moretransgenes encoding one or more of the PKS-like genes associated with suchlong chain poly-unsaturated fatty acid production. Expression of the PKS-likegenes in the plant system permits the large scale production of poly-unsaturated long chain fatty acids such as eicosapentenoic acid anddocosahexonoic acid for modification of the fatty acid profile of plants,plant parts and tissues. Manipulation of the fatty acid profiles allows forthe production of commercial quantities of novel plant oils and products.
