Patent number: 9587245Abstract: Transformed Phaeodactylum tricornutum including a nucleic acid sequence operatively linked to a promoter, wherein the nucleic acid sequence encodes an N-acetylglucosaminyltransferase I and/or an ?-Mannosidase II and wherein at least one ?-N-acetylglucosaminidase of the transformed Phaeodactylum tricornutum has been inactivated. A method for producing a glycosylated polypeptide includes the steps of (i) culturing a transformed P. tricornutum as defined previously and (ii) purifying the polypeptide that is expressed and glycosylated in the transformed P. Tricornutum.

Publication number: 20110008837Abstract: A method for synthesizing a protein of interest with a modified N-glycosylation profile within a plant, a portion of a plant, or a plant cell is provided. The method comprises co-expressing within a plant a nucleotide sequence encoding a first nucleotide sequence encoding a hybrid protein (GNT1-GalT) comprising a CTS domain of N-acetylglucosaminyl transferase (GNT1) fused to a catalytic domain of beta-1,4galactosyltransferase (GalT), the first nucleotide sequence operatively linked with a first regulatory region that is active in the plant, and a second nucleotide sequence for encoding the protein of interest, the second nucleotide sequence operatively linked with a second regulatory region that is active in the plant. The first and second nucleotide sequences are co-expressed to synthesize a protein of interest comprising glycans with the modified N-glycosylation profile within the plant, the portion of the plant, or the plant cell.Type: ApplicationFiled: June 13, 2008Publication date: January 13, 2011Inventors: Marc-Andre D-Aoust, Louis-Philippe Vezina, Stephanie Aquin, Estelle Marquet-Blouin, Muriel Bardor, Veronique Gomord, Christophe Rihouey, Thomas Paccalet, Carole Burel, Loic Faye, Patrice Lerouge, Christophe Sourrouille

Patent number: 5549718Abstract: An essentially pure substance has a structure of a Nod factor or one of its analogues. The Nod factor is characterized by the fact that its biosynthesis is controlled by at least one nodulation gene (nodA,B,C) common to the Rhizobiaceae, in particular to the genera Rhizobium, Bradyrhizobium, Sinorhizobium and Azorhizobium. This substance consists of a lipo-oligosaccharide which is not a derivative of the exopolysaccharides and which has the general formula (I). In formula (I), the Nod factor of which it has the structure is a plant-specific symbiotic signal and is capable of enhancing the capacity of the bacteria of infect the host plant with which it is associated and/or of accelerating the formation of nodules on the host plant with which it is associated and/or of inducing the transcription of symbiotic genes of the leguminoseae. Applications to the treatment of plants and as an active therapeutic agent in humans and animals.Type: GrantFiled: September 30, 1994Date of Patent: August 27, 1996Assignees: Centre National de la Recherche Scientifique (C.N.R.S.), Institut National de la Recherche Agronomique (I.N.R.A.)Inventors: Patrice Lerouge, Philippe Roche, Catherine Faucher, Fabienne Maillet, Jean Denarie, Jean-Claude Prome, Georges Truchet
