    Keywords : MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; xyloglucan; xyloglucan endo-transglycosylase hydrolase; xyloglucan endo-hydrolase; xyloglucan endo-transglycosylase; XET; xyloglucan oligosaccharides; synthesis; carbohydrate; cellulose; crystal structure; fiber; surface modification; Populus tremula x Populus tremuloides; Hybrid aspen; nasturtium; NXG; Biochemistry; Biokemi;

    Abstract : Cellulosabaserade material är världens rikligast förekommande förnyelsebara råvara. Växters cellväggar är naturliga kompositmaterial där den kristallina cellulosan är inbäddad i en väv av hemicellulosa, strukturproteiner och lignin. READ MORE

  4. 2. Cellulose synthases in Populus- identification, expression analyses and in vitro synthesis

    Author : Soraya Djerbi; Tuula Teeri; Petter Gustafsson; KTH; []
    Keywords : ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; cellulose synthase; Populus; secondary cell wall; gene upregulation; cell suspension culture; stationary phase; Bioengineering; Bioteknik;

    Abstract : Cellulose is a biopolymer of great relevance in the plant cell walls, where it constitutes the most important skeletal component. Cellulose is also an important raw material in the pulp- and paper, forest, and textile industries, among others. READ MORE

    Abstract : Xyloglucans are polysaccharides found as storage polymers in seeds and tubers, and as cross-linking glycans in the cell wall of plants. Their structure is complex with intricate branching patterns, which contribute to the physical properties of the polysaccharide including its binding to and interaction with other glycans such as cellulose.

    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.
