摘要：
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.
