  • Patent number: 7524943
    Abstract: The present invention relates to nucleotide sequences commonly designated CJAS1 comprising a novel gene from plants. The novel gene encodes a protein that is involved in seed formation and is associated with plant defense. The invention further relates to the use of the nucleotide sequence in the sense or antisense orientation to inhibit the expression of the plant gene corresponding to the CJAS1 sequence as a means to alter seed metabolism in plants, particularly cruciferous plants, more particularly Brassica species, to generate seeds with reduced fiber content and/or altered seed coats. The invention also relates to similar genes expressed in other plant species. The invention also relates to the discovery that the CJAS1 gene is involved in proanthocyanidin (PA) formation.
    Type: Grant

  • Publication number: 20080145867
    Abstract: Nucleic acid molecules identified in encode lyso-phosphatidylcholine (LPC) acyltransferases. Over-expression of the LPC acyltransferases in a cell may lead to enhanced production of PUFA, or other unusual fatty acids, and/or to increased oil content in the cell.

  • Publication number: 20060206960
    Abstract: Glycerol-3-phosphate acyltransferase is the initial enzyme of the glycerolipid biosynthetic pathway. Biochemical analyses indicated that the reaction mediated by glycerol-3-phosphate acyltransferase represents a potential rate-limiting step for the synthesis of phospholipids and storage neutralipid, triacylglycerol. The present invention relates to the cloning of genes encoding extraplastidic membrane-bound glycerol-3-phosphate acyltransferases. Heterologous expression of the genes, GPAT1, GPAT2, and GPAT3 in a yeast glycerol-3-phosphate acyltransferase mutant demonstrated that the encoded products could efficiently utilize glycerol-3-phosphate to mediate sn-1 stereo-specific fatty acid acylation.
