Dgat genes from oleaginous organisms for increased seed storage lipid production and altered fatty acid profiles in oilseed plants

An isolated polynucleotide comprising:

• (a) a nucleotide sequence encoding a polypeptide having diacylglycerol acyltransferase activity wherein the polypeptide has at least 80% amino acid identity, based on the Clustal V method of alignment, when compared to an amino acid sequence as set forth in SEQ ID NOs:135, 136, 147, 162, 176, 215, 234, 265, 272, 279, 299, 304, 306, 308, 310, 312, 314, 316, 318, 320, 322, 351, or 363;
• (b) a nucleotide sequence encoding a polypeptide having diacylglycerol acyltransferase activity, wherein the nucleotide sequence has at least 80% sequence identity, based on the BLASTN method of alignment, when compared to a nucleotide sequence as set forth in SEQ ID NO:
• 133, 134, 146, 161, 175, 214, 233, 264, 271, 278, 298, 301, 303, 305, 307, 309, 311, 313, 315, 317, 319, 321, 350, or 352;
• (c) a nucleotide sequence encoding a polypeptide having diacylglycerol acyltransferase activity, wherein the nucleotide sequence hybridizes under stringent conditions to a nucleotide sequence as set forth in SEQ ID NO:
• 133, 134, 146, 161, 175, 214, 233, 264, 271, 278, 298, 301, 303, 305, 307, 309, 311, 313, 315, 317, 319, 321, 350, or 352;
• or
• (d) a complement of the nucleotide sequence of (a), (b) or (c), wherein the complement and the nucleotide sequence consist of the same number of nucleotides and are 100% complementary.
