Abstract
The use of a gene expressing a SMT1 to increase the level of sterols or decrease the amount of cholesterol in the seeds of plants.
Claims15
The use of a gene expressing a SMT1 to increase the level of sterols in the seeds of plants and/or decrease the level of cholesterol in plant tissue.
The use according to one or more of the preceding claims, wherein the level of sterols is increased in the seeds by at least 10%, more preferred at least 25%, most preferred at least 30%.
Method of obtaining seeds by
- (a)Transforming a plant by:
- 1. transforming a plant cell with a recombinant DNA construct comprising a DNA segment encoding a polypeptide with SMT1 activity and a promoter for driving the expression of said polypeptide in said plant cell to form a transformed plant cell.
- 2. regenerating the transformed plant cell into the transgenic plant.
- 3. selecting transgenic plants that have enhanced levels of sterols or decreased levels of cholesterol in the seeds compared wild type strains of the same plant
- (b)cultivating the transformed plant for one or more generations;
- (c)harvesting seed from the plant grown under(b).
Seeds having enhanced level of sterols and produced by a plant having increased SMT1 activity.
A method to increase the level of sterols in the seeds of plants and/or decrease the level of cholesterol in plant tissue by increasing the expression of SMT1 in said plants.
Plant tissue having decreased levels of cholesterol, said plant tissue being derived from a plant having increased SMT1 activity.
