Isolated polynucleotides encoding Brassica napus diacylglycerol
O-acyltransferase (DGAT) are provided. Also provided are the encoded DGAT
polypeptides, transgenic plants which express DGAT, and methods for making
such plants. The DGAT-encoding polynucleotides are useful for increasing
triacylglycerol (TAG) synthesis, seed oil content, and oil quality in
plants.
