Novel nucleic acids derived from the 5' untranslated regions of the 2S albumin and 11S globulin genes from sesame are disclosed. These novel nucleic acids can be used to direct expression of coding nucleic acids. Expression constructs can be introduced into a plant cell to generate a transgenic plant cell or to generate a transgenic plant.

Nucleic acids from sesame plants

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

A gene encoding diacylglycerol acyltransferase fromis described, as well as methods of altering oil content in plants using the diacylglycerol acyltransferase.

Plant acyltransferases

Plants are disclosed that contain a recombinant nucleic acid construct comprising a nucleic acid encoding a cytosolic acetyl coA-carboxylase (ACCase) operably linked to a promoter. Seeds produced from such plants exhibit statistically significantly increased oil content as compared to seeds produced by a corresponding plant lacking the nucleic acid encoding the ACCase. Methods of producing seeds exhibiting statistically significantly increased oil content are also disclosed.

Plants containing a cytosolic acetyl CoA-carboxylase nucleic acid

Fatty acid desaturase 5&prime; regulatory elements are described, as well as nucleic acid constructs and transgenic plants that include these regulatory elements. Also described are fatty acid desaturase 3&prime; untranslated regions.
