FATTY ACID DESATURASES FROM FUNGI

摘要

The invention relates generally to methods and compositions concerning fungal desaturase enzymes that modulate the number and location of double bonds in long chain poly-unsaturated fatty acids (LC-PUFA's). In Particular, the invention relates to methods and compositions for improving omega-3 fatty acid profiles in plant products and parts using desaturase enzymes and nucleic acids encoding for such enzymes. In particular embodiments, the desaturase enzymes are fungal -15 desaturases. Also provided are improved canola oil compositions having SDA and maintaining beneficial oleic acid content.
