Abstract:
PROBLEM TO BE SOLVED: To provide a means for optimizing glycan processing in plants.SOLUTION: The invention is directed to methods for optimizing glycan processing of a cell or a living tissue, in particular a plant, containing glycoproteins with N-glycans, so that a glycoprotein, having a complex type double-stranded N-glycan containing a galactose residue on at least one arm and being devoid of (or reduced in) xylose and fucose residues, can be obtained. The invention is further directed to the glycoprotein obtained and in particular a plant host system comprising the protein.
Abstract:
PROBLEM TO BE SOLVED: To provide GnTIII expression in a plant. SOLUTION: A field of glycoprotein processing in transgenic plants used as cost-efficient and contamination possibility-free factories for the production of recombinant biopharmaceutical proteins or pharmaceutical compositions comprising glycoproteins, is provided. In the field, a plant contains a functional mammalian enzyme providing mammalian GnTII (EC 2.4.1.144)I that is normally not present in plants, wherein the plant additionally contains at least a second mammalian protein or functional fragment thereof that is normally not present in plants.

Abstract:
Disclosed is a method of making methacrylic acid, or a carboxylic derivative thereof, from itaconic acid, isomers, or precursors thereof. A starting material comprising an acid selected from the group consisting of itaconic acid, citraconic acid, mesaconic acid, citric acid, aconitic acid, isocitric acid and mixtures thereof, is subjected to contact with 0.1 eq. to 3.0 eq. of a base, at a temperature of 150° C. to 350° C., under the influence of a transition metal-containing heterogeneous catalyst. A better yield at lower temperatures is achieved.
Abstract:
Disclosed is a method of making 5-formyl-2-furoic acid and furan-2,5-dicarboxylic acid. The method involves the use of 5-keto-aldonic acids as intermediates, as these can be subjected to ring formation by a cyclodehydration reaction under mild conditions. The 5-formyl-2-furoic acid or carboxylic derivative thereof is subjected to oxidation so as to form furan-2,5-dicarboxylic acid. The 5-keto-aldonic acid intermediates can be obtained by isomerization of uronic acids which can be obtained from sugar beet pulp, chicory pulp, fruit peals including orange peels, or non-terrestrial sources like seaweeds. A preferred source is sugar beet pulp.

Abstract:
This invention provides a novel means of predicting plant phenotypes that incorporates previously unusable dense marker data derived from historical pedigrees. The method operates by collecting information from a population pertaining to one or more loci, which is used to build one or more matrices by calculating, for the alleles present at the measured loci, the probability that the alleles are identical by descent. These matrices are then used to develop a second set of one or more matrices in which each value represents the probability that a certain individual in the population descended from a certain ancestral (founder) genotype. This set of second matrices can then be used as part of a breeding program for selecting and breeding individuals from the population or can be used to better classify the individuals in the population, leading to improved plant phenotypes.
Abstract:
The present invention relates to non-mammalian β-1,4-galactosyltransferases that can be used in their wild-type or in modified forms. The invention further relates to transformed plants and plant cells expressing non-mammalian β-1,4-galactosyltransferases and methods to produce glycoproteins with altered and preferably mammalian-type glycosylation. The invention additionally provides nucleic acid molecules and expression vectors of non-mammalian β-1,4-galactosyltransferases.
