Abstract
Official abstract text for this publication.
The invention relates generally to the expression of desaturase enzymes in transgenic corn plants and compositions derived therefrom. In particular, the invention relates to the production of oils with improved omega-3 fatty acid profiles in corn plants and the seed oils produced thereby. Such oils may contain stearidonic acid, which is not naturally found in corn plants and has been shown to have beneficial effects on health.
First claim
Opening claim text (preview).
The invention claimed is: 1. An endogenous corn seed oil having an endogenous stearidonic acid (18:4 n-3) content of from about 5% to about 33% and further endogenously comprising gamma-linolenic acid, wherein the ratio of stearidonic acid to gamma-linolenic acid is at least 3:1. 2. The endogenous corn seed oil of claim 1 , wherein the stearidonic acid content is about 15% to about 32%. 3. The endogenous corn seed oil of claim 1 , wherein the corn seed oil is defined as endogenously comprising gamma-linolenic acid in a content of less than 7.5%. 4. The endogenous corn seed oil of claim 1 , wherein the ratio of stearidonic acid to gamma-linolenic acid is from 3:1 to about 10:1. 5. The endogenous corn seed oil of claim 1 , wherein the ratio of omega-3 to omega-6 fatty acids in the oil is selected from the group consisting of from about 0.5:1 to about 10:1, from about 5:1 to about 10:1, and at least 5:1. 6. The endogenous corn seed oil of claim 1 , wherein the stearidonic acid content is about 10% to about 33%. 7. The endogenous corn seed oil of claim 1 , wherein the stearidonic acid content is about 20% to about 30%. 8. The endogenous corn seed oil of claim 1 , wherein the stearidonic acid content is about 25% to about 30%. 9. The endogenous corn seed oil of claim 1 , wherein the corn seed oil is defined as endogenously comprising gamma-linolenic acid in a content of less than 5%. 10. The endogenous corn seed oil of claim 1 , wherein the corn seed oil is defined as endogenously comprising gamma-linolenic acid in a content of less than 3%. 11. The endogenous corn seed oil of claim 1 , wherein the ratio of stearidonic acid to gamma-linolenic acid is from 3:1 to about 5:1.
