  2. 11. Analysis of Genes and Proteins Involved in Wood Formation

    Author : Anders Winzell; Tuula Teeri; Alan Marchant; KTH; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Biochemistry; Biokemi;

    Abstract : SAMMANFATTNING Vedbildning är en underliggande mekanism för så skilda områden som industri, boende och en hållbar miljö. Vedbildning sker i det vaskulära kambiet där organiserade celldelningar åtföljs av differentiering till specialiserade vedceller. READ MORE

  4. 12. Investigation of genes and proteins involved in xylan biosynthesis

    Author : Anders Winzell; Ines Ezcurra; Johan Edqvist; KTH; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Populus; xylan biosynthesis; hemicellulose; glycosyltransferase; GT43; IRX; glycoside hydrolase; GH10; Xyn10A; CAZy; transcription factor; MYB; wood formation; secondary cell wall; Arabidopsis; Molecular biology; Molekylärbiologi;

    Abstract : Wood formation or xylogenesis is a fundamental process for so diverse issues as industry, shelter and a sustainable environment. Wood is comprised of secondary xylem, rigid large cells with thick cell walls that are lignified. READ MORE

  5. 13. A study of the molecular pathways of wood formation using peptide mass spectrometry

    Author : Robert Nilsson; Sveriges lantbruksuniversitet; Sveriges lantbruksuniversitet; []
    Keywords : LANTBRUKSVETENSKAPER; AGRICULTURAL SCIENCES;

    Abstract : Wood consists essentially of secondary plant cell walls, composed of a cellulose and hemicellulose network impregnated with lignin. It is formed via the development of derivatives of a thin layer of cells (the vascular cambium) into xylem cells through cell division, expansion, secondary wall formation, lignification and, finally, programmed cell death.

  6. 14. Composition of lignin in outer cell-wall layers

    Author : Maria Christiernin; Gunnar Henriksson; Gösta Brunow; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Lignin; thioacidolysis; primary wall; middle lamella; Populus balsamifera; Populus tremula L. x P. tremuloides Michx.; Picea abies; Picea glauca; Cellulose and paper engineering; Cellulosa- och pappersteknik;

    Abstract : The composition of lignin in the outer cell-wall layers of spruce and poplar has been studied and the data obtained have been compared with those of the mature reference wood in which the secondary cell wall predominates. Materials with exclusively or predominantly outer cell-wall layers were examined. READ MORE

  7. 15. Modification of forest trees by genetic engineering : from design to the field

    Author : Evgeniy Donev; Sveriges lantbruksuniversitet; Sveriges lantbruksuniversitet; []
    Keywords : LANTBRUKSVETENSKAPER; AGRICULTURAL SCIENCES;

    Abstract : Developing viable genetic engineering methods for cell wall modification in trees is important to improve in a timely manner the properties of lignocellulose for biorefinery applications. New wood cell wall functionalities can be introduced by altered expression of native enzymes or by expressing microbial enzymes in planta. READ MORE
