Canola oils from hybridvarieties and methods for producing hybridvarieties are described. The hybrid seeds have a low, mid, or high oleic acid content and a low linolenic acid content.

[object Object]

Seeds, plants and oils are provided having high oleic acid; low linoleic acid; and low linoleic acid plus linolenic acid; and advantageous functional or nutritional properties. Plants are disclosed that contain a mutation in a delta-12 or delta-15 fatty acid desaturase gene. Preferred plants are rapeseed and sunflower plants. Plants carrying such mutant genes have altered fatty acid composition in seeds. In one embodiment, a plant contains a mutation in a region having the conserved motif His-Xaa-Xaa-Xaa-His, found in delta-12 and delta-15 fatty acid desaturases. A preferred motif has the sequence His-Glu-Cys-Gly-His. A preferred mutation in this motif has the amino acid sequence His-Lys-Cys-Gly-His. Nucleic acid fragments are disclosed that comprise a mutant delta-12 or delta-15 fatty acid desaturase gene sequence.

Fatty acid desaturases and mutant sequences thereof

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.

Methods for decreasing linolenic acid content in seeds from transgenic plants containing a mutant delta 15 desaturase

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 mutant delta-12 fatty acid desaturase nucleic acid fragments with suitable regulatory sequences may be used to create transgenic plants with altered levels of unsaturated fatty acids.

Methods for increasing oleic acid content in seeds from transgenic plants containing a mutant delta 12 desaturase

Seeds, plants and oils are provided having low FDA saturates; high oleic acid; low linoleic acid; high or low palmitic acid; low stearic acid; and low linoleic acid plus linolenic acid; and advantageous functional or nutritional properties.

Seeds, plants and oils with altered fatty acid profiles

The oil from a canola seed with an altered fatty acid profile is disclosed to have low FDA saturates; high oleic acid; low linoleic acid; low stearic acid; and low linoleic acid plus linolenic acid. The method for extracting the oil from the seeds is also disclosed.
