Abstract:
1. A polynucleotide molecule comprising a nucleic acid sequence selected from the group consisting of: a) a nucleic acid sequence encoding the polypeptide sequence of SEQ ID NO:2 or SEQ ID NO:4; b) a nucleic acid sequence of SEQ ID NO:1 or SEQ ID NO:3; c) a nucleic acid sequence that hybridizes to SEQ ID NO:1 or SEQ ID NO:3 or a complement thereof, under conditions of 5×SSC, 50% formamide and 42° C. and encodes a polypeptide having desaturase activity that desaturates a fatty acid molecule at carbon 5; and d) a nucleic acid sequence encoding a polypeptide with at least 75% sequence identity to a polypeptide sequence of SEQ ID NO:2 or SEQ ID NO:4 having desaturase activity that desaturates a fatty acid molecule at carbon 5, wherein the polynucleotide molecule is operable linked to a heterologous promoter.
