Compositions and methods for engineering oil content in plants

Abstract

Compositions and methods for producing plants with enhanced oil content and higher seed yield are disclosed. The transgenic plant comprises a polynucleotide encoding a monoacylglycerol O-acyltransferase 1 (MGAT1) operatively linked to a plant-expressible promoter; a polynucleotide encoding a phosphatidylcholine diacylglycerol cholinephosphotransferase 1 (PDCT1) operatively linked to a plant-expressible promoter; a polynucleotide encoding a suppressor of expression of Sugar Dependent 1 (SPD1) operatively linked to a plant-expressible promoter; a polynucleotide encoding a diacylglyerol acyltransferase (DGAT1) operatively linked to a plant-expressible promoter and a polynucleotide encoding a glycerol-3-phosphate dehydrogenase (GPD1) operatively linked to a plant-expressible promoter; or a combination thereof.
