Brassicaceae plants are disclosed that contain a mutation in a delta-12 fatty acid desaturase gene and that have altered fatty acid composition in seeds. In one embodiment, a Brassicaceae 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.

Plants having mutant delta-12 desaturase sequences that confer altered fatty acid profiles

A non-hydrogenated canola oil having superior oxidative stability and fry stability useful for food applications is disclosed, as well as seeds, plant lines and progeny thereof from which the oil is derived.

Non-hydrogenated canola oil for food applications

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-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 sequence of at least 20 nucleotides from a mutant delta-12 or delta-15 fatty acid desaturase gene.

Brassica or helianthus plants having mutant delta-12 or delta-15 sequences

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.

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

A canola line has been stabilized to produce seeds having an &agr;-linolenic acid content of less than that of generic canola oil, more preferably less than or equal to about 7% &agr;-linolenic acid relative to total fatty acid content of said seed and a total glucosinolate content of less than 18 &mgr;mol/g of defatted meal, more preferably less than or equal to about 15 &mgr;mol/g of defatted meal. This canola line has reduced sulfur content of less than or equal to 3.0 ppm, improved sensory characteristics and increased oxidative stability.

Canola oil with reduced linolenic acid

Plants, seeds and oils having a total long chain monounsaturated content of at least about 82% and an erucic acid content of at least about 15% are described. Methods for producing plants having the profiled fatty acid content are also described.

Plants, seeds and oils having an elevated total monounsaturated fatty acid content

Canola meal having reduced glucosinolates

A triacylglycerol containing oil having a 1,3-dierucoyl 2-oleoyl glycerol (EOE) content of at least 50% is described. Plants for producing an oil having a high EOE content are also described.

Biodegradable high oxidative stability oils

Brassica seeds having a maximum of glucosinolate content of 3.4 &mgr;moles per gram of seed, plant lines and progeny thereof which produces such seeds, and meal derived from such seeds are disclosed.

Low level glucosinolate Brassica

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.
