Abstract
Isolated nucleic acid fragments and recombinant constructs comprising such fragments encoding a delta-8 desaturase along with a method of making long chain polyunsaturated fatty acids (PUFAs) using this delta-8 desaturase in plants and oleaginous yeast.
Claims10
An isolated polynucleotide comprising:
- (a) a nucleotide sequence encoding a polypeptide having delta-8 desaturase activity, wherein the polypeptide has the amino acid sequence as set forth in SEQ ID NO:113;
- or,
- (b) a complement of the nucleotide sequence, wherein the complement and the nucleotide sequence consist of the same number of nucleotides and are 100% complementary.
An oil-producing oleaginous yeast cell comprising a recombinant DNA construct comprising an isolated nucleotide sequence encoding a polypeptide having delta-8 desaturase activity, wherein the polypeptide has the amino acid sequence as set forth in SEQ ID NO:113.
