  2. 1. Spectroscopic data and multivariate analysis : tools to study genetic perturbations in poplar trees

    Author : Susanne Wiklund; Ulf Edlund; Olav Kvalheim; Umeå universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; NMR spectroscopy; Metabolomics; Degree of methylation; S-plot; SUS-plot; Metabonomics; Poplar; MLR; PLS; OPLS; PCA; Pectin; Wood; Organic chemistry; Organisk kemi;

    Abstract : In our society in the 21st century one of the greatest challenges is to provide raw materials to the industry in a sustainable way. This requires increased use of renewable raw materials such as wood. Wood is widely used in pulp, paper and textile industries and ongoing research efforts aim to extend the use of wood in e.g. READ MORE

  4. 2. Gene regulation of UDP-glucose synthesis and metabolism in plants

    Author : Henrik Johansson; Pierdomenica Perata; Umeå universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Molecular biology; antisense; Arabidopsis thaliana; carbohydrate; hybrid aspen; photosynthesis; poplar; sugar; UDP-glucose; UDP-glucose pyrophosphorylase; UDP-glucose dehydrogenase; Molekylärbiologi; Molecular biology; Molekylärbiologi; molekylärbiologi; Molecular Biology;

    Abstract : Photosynthesis captures light from the sun and converts it into carbohydrates, which are utilised by almost all living organisms. The conversion between the different forms of carbohydrates is the basis to form almost all biological molecules. READ MORE

  5. 3. Biochemical and Physiological Characterization of Nonsymbiotic Plant Hemoglobins

    Author : Nélida Leiva; Tillämpad biokemi; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Hemoglobin; Non-symbiotic hemoglobin; Sugar beet; Ligand binding; Nitric oxide; Gene expression; Gene overexpression; Poplar; Arabidopsis; Lepidium campestre.;

    Abstract : Hemoglobins (Hb) are usually associated with blood in humans. However, these proteins are widely distributed among living organisms. In plants the most known group are the leghemoglobins. Still, other Hbs that not participate in symbiosis are also found. READ MORE

  7. 5. Functional studies of a membrane-anchored cellulase from poplar

    Author : Ulla Jonsson Rudsander; Tuula Teeri; Eva Nordberg-Karlsson; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Populus; cellulose biosynthesis; endo-1; 4-b-glucanase; cellulase; Pichia pastoris; Arabidopsis thaliana; NMR spectroscopy; cleavage pattern; stereochemistry; transglycosylation; complementation; hybrid proteins; overexpression; substrate analysis; overglycosylation; Bioengineering; Bioteknik;

    Abstract : Cellulose in particular and wood in general are valuable biomaterials for humanity, and cellulose is now also in the spotlight as a starting material for the production of biofuel. Understanding the processes of wood formation and cellulose biosynthesis could therefore be rewarding, and genomics and proteomics approaches have been initiated to learn more about wood biology.
