Abstract
Official abstract text for this publication.
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.
First claim
Opening claim text (preview).
That which is claimed: 1. A soybean plant seed with increased oil content comprising in its genome: (a) a first recombinant DNA construct comprising a first polynucleotide operably linked to at least one first regulatory element, wherein said first polynucleotide comprises a diacylglycerol acyltransferase (DGAT) coding region encoding a polypeptide having at least 95% sequence identity to SEQ ID NO:180, based on the Clustal W method of alignment with pairwise alignment default par…
