DGAT genes from <i>Yarrowia lipolytica </i>for increased seed storage lipid production and altered fatty acid profiles in soybean

摘要

Transgenic soybean seed having increased total fatty acid content of at least 20% 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 combined with plastidic phosphoglucomutase down regulation are used to achieve the increase in seed storage lipids.

1. A transgenic soybean seed having increased total fatty acid content of at least 20% when compared to the total fatty acid content of a non-transgenic, null segregant soybean seed wherein said seed comprises at least one recombinant construct having at least one DGAT sequence, a construct downregulating plastidic phosphoglucomutase activity and a construct downregulating GAS activity wherein the DGAT sequence, the plastidic phosphoglucomutase and GAS construct can be in the same recombinant construct or in separate recombinant constructs.
