Patent ID: 7608753

Claim:
A genetically modified plant, wherein cells of the plant are transfected with at least one recombinant nucleic acid molecule encoding a polyketide synthase (PKS) system for the production of polyunsaturated fatty acids (PUFAs), wherein the PKS system comprises the following proteins: a) a protein comprising an amino acid sequence that is at least 95% identical to SEQ ID NO:39 and has β-keto acyl-ACP synthase (KS) activity, malonyl-CoA:ACP acyltransferase (MAT) activity, acyl carrier protein (ACP) activity and ketoreductase (KR) activity; b) a protein comprising an amino acid sequence that is at least 95% identical to SEQ ID NO:52 and has β-keto acyl-ACP synthase (KS) activity, chain length factor (CLF) activity, acyl transferase (AT) activity, and enoyl ACP-reductase (ER) activity; and c) a protein comprising an amino acid sequence that is at least 95% identical to SEQ ID NO:62 and has FabA-like β-hydroxy acyl-ACP dehydrase (DH) activity and enoyl ACP-reductase (ER) activity.
