New plant nucleic acid encoding polyunsaturated fatty acid elongase, useful for producing transgenic organisms with increased content of long-chain unsaturated fatty acids

摘要

Isolated nucleic acid (I), of plant origin, encoding a polypeptide (II) that extends C18 fatty acids, containing at least to double bonds, by at least two carbon atoms. Independent claims are also included for the following: (a) (II) encoded by (I); (b) gene construct containing a 1192 bp sequence (1; reproduced), functionally linked to regulatory signals; (c) vector containing (I) or the construct of (b); (d) organisms containing (I), the construct of (b) or the vector of (c); (e) method for producing polyunsaturated fatty acids (PUFAs) by growin organisms of (d); (f) oils, lipids, fatty acids or their fractions produced by method (e); and (g) oils, lipids and fatty acid compositions containing PUFAs and derived from transgenic plants. ACTIVITY : Hypocholesterolemic; cardiovascular. MECHANISM OF ACTION : None given.
