Abstract
The present specification relates to the production of cotton plants and seeds and oil prepared therefrom having elevated levels of oleic and reduced levels of palmitic and linoleic acids. Furthermore, cottonseeds having low levels of cyclopropane and/or cyclopropene fatty acids and/or reduced levels of gossypol are described herein. The specification also describe FatB and CPA-FAS nucleotide and amino acid sequences derived from cotton facilitating, inter alia the direct modification of plant oil content and/or composition.
Claims16
A process for producing cottonseed oil comprising the steps of
- (i) obtaining cottonseed of the species Gossypium hirsutum, wherein in the oil of the cottonseed 72% to 88% by weight of the total fatty acid content is oleic acid, 4% to 16% by weight of the total fatty acid content is palmitic acid and 4% to 15% by weight of the total fatty acid content is linoleic acid, and wherein the cottonseed has a reduced level of each of cotton FAD2-1 protein, cotton FatB-2 protein, and cotton CPA-FAS-2 protein relative to the level of cotton FAD2-1 protein, cotton FatB-2 protein, and cotton CPA-FAS-2 protein, respectively, in cottonseed of cotton variety Coker when grown under the same conditions;
- (ii) extracting the oil from the cottonseed;
- and
- (iii) recovering the cottonseed oil.
A cottonseed of the species Gossypium hirsutum comprising oil, wherein in the oil of the cottonseed 72% to 88% by weight of the total fatty acid content is oleic acid, 4% to 16% by weight of the total fatty acid content is palmitic acid and 4% to 15% by weight of the total fatty acid content is linoleic acid, and wherein the cottonseed has a reduced level of each of cotton FAD2-1 protein, cotton FatB-2 protein and cotton CPA-FAS-2 protein relative to the levels of cotton FAD2-1 protein, cotton FatB-2 protein and cotton CPA-FAS-2 protein respectively, in cottonseed of cotton variety Coker when grown under the same conditions.
