Patent ID: 7863502

Claim:
An isolated polynucleotide comprising: (a) a nucleotide sequence encoding a polypeptide having delta-8 desaturase activity, wherein the polypeptide has at least 80% amino acid identity, based on the Clustal V method of alignment, when compared to an amino acid sequence as set forth in SEQ ID NO:47, SEQ ID NO:49 or SEQ ID NO:57; (b) a nucleotide sequence encoding a polypeptide having delta-8 desaturase activity, wherein the nucleotide sequence has at least 80% sequence identity, based on the BLASTN method of alignment, when compared to a nucleotide sequence as set forth in SEQ ID NO:92, SEQ ID NO:93 or SEQ ID NO:62; (c) a nucleotide sequence encoding a polypeptide having delta-8 desaturase activity, wherein the nucleotide sequence hybridizes under stringent conditions to a nucleotide sequence as set forth in SEQ ID NO:92, SEQ ID NO:93 or SEQ ID NO:62; or (d) a complement of the nucleotide sequence of (a), (b) or (c), wherein the complement and the nucleotide sequence consist of the same number of nucleotides and are 100% complementary.
