FATTY ACID DESATURASE GENES FROM PLANTS

The preparation and use of nucleic acid fragments encoding fatty acid desaturase enzymes are described. The invention permits alteration of plant lipid composition. Chimeric genes incorporating such nucleic acid fragments with suitable regulatory sequences may be used to create transgenic plants wit...

Beschreibung
Zusammenfassung:	The preparation and use of nucleic acid fragments encoding fatty acid desaturase enzymes are described. The invention permits alteration of plant lipid composition. Chimeric genes incorporating such nucleic acid fragments with suitable regulatory sequences may be used to create transgenic plants with altered levels of unsaturated fatty acids. L'invention décrit la préparation et l'utilisation de fragments d'acide nucléique codant des enzymes de désaturase d'acides gras. L'invention permet de modifier la composition des lipides des plantes. On peut utiliser des gènes chimères incorporant lesdits fragments d'acide nucléique avec des séquences régulatrices appropriées, afin de créer des plantes transgéniques présentant des niveaux modifiés d'acides gras insaturés.
