    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.

    Abstract: This invention relates to polynucleotide sequences encoding SUT2 or SUT4 sucrose transporter genes. Methods for increasing seed oil content and evaluating increased oil content in a plant seed are described. The compositions and methods disclosed herein employ a variety of sequences that encode sucrose transporters and a variety of sequences that influence fatty acid accumulation, including for example, DGAT, Lec1 and ODP1 transcription factor. In specific embodiments, overexpression of SUT2 and/or SUT4 sucrose transporters in combination with DGAT genes further increase plant seed oil production compared to a high oil plant comprising recombinant DNA constructs that do not overexpress SUT2 or SUT4 transporters.
