Abstract
Transgenic soybean seed having increased total fatty acid content of at least 10% and altered fatty acid profiles when compared to the total fatty acid content of non-transgenic, null segregant soybean seed are described. DGAT genes from Yarrowia Lipolytica are used to achieve the increase in seed storage lipids.
Claims5
A transgenic soybean seed having increased total fatty acid content of at least 10% when compared to the total fatty acid content of a non-transgenic, null segregant soybean seed.
2-42. (canceled)
Meal obtained from a transgenic soybean seed having increased total fatty acid content of at least 10% when compared to the total fatty acid content of a non-transgenic, null segregant soybean seed, wherein said transgenic seed comprises a recombinant construct having at least one DGAT sequence, further wherein protein content is increased when compared to the protein content of a meal obtained from a non-transgenic, null segregant soybean seed.
A method for increasing the protein content of a meal obtained from a soybean seed comprising:
- (a) transforming at least one soybean cell with at least one recombinant construct having at least one DGAT sequence;
- (b) selecting the transformed soybean cell(s) of step (a) having an increased total fatty acid content of at least 10% and an increased protein content of at least 1.5% when compared to the total fatty acid content and protein content of a non-transgenic, null segregant soybean seed.
- (c) preparing a meal from the soybean seed of step (b).
