Patent ID: 8119784

Claim:
An isolated nucleic acid molecule selected from the group consisting of: (a) an isolated nucleotide sequence encoding a delta-4 desaturase enzyme selected from the group consisting of SEQ ID NO:2 and SEQ ID NO:4; (b) an isolated nucleotide sequence encoding a delta-4 desaturase enzyme that hybridizes with (a) under the following stringent hybridization conditions: 0.1×SSC, 0.1% SDS, 65° C. and washed with 2×SSC, 0.1% SDS followed by 0.1×SSC, 0.1% SDS; (c) an isolated nucleotide sequence encoding a delta-4 desaturase enzyme having at least 90% identity when compared to a polypeptide haying the amino acid sequence as set forth in SEQ ID NO:2, based on the Clustal W method of alignment; and, (d) an isolated nucleotide sequence that is completely complementary to (a), (b) or (c).
