  • DGAT genes from for increased seed storage lipid production and altered fatty acid profiles in soybean
    Patent number: 8143473
    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.

  • lysophosphatidic acid acyltransferase homolog for alteration of polyunsaturated fatty acids and oil content in oleaginous organisms
    Patent number: 7524658
    Abstract: Lysophosphatidic acid acyltransferase (LPAAT) participates in the second step of oil biosynthesis and is expected to play a key role in altering the quantity of long-chain polyunsaturated fatty acids produced in oils of oleaginous organisms. The present application provides a nucleic acid fragment (identified as “LPAAT2”) isolated from Mortierella alpina encoding a LPAAT homolog that is suitable for use in the manufacture of oils enriched in omega fatty acids in oleaginous organisms. Most desirably, the substrate specificity of the instant LPAAT2 will be particularly useful to enable accumulation of long-chain PUFAs having chain lengths equal to or greater than C20 in oleaginous yeast, such as Yarrowia lipolytica.
