  2. 6. Combined profiling in aspen : a systems biology approach

    Author : Ogonna Obudulu; Sveriges lantbruksuniversitet; Sveriges lantbruksuniversitet; []
    Keywords : LANTBRUKSVETENSKAPER; AGRICULTURAL SCIENCES; LANTBRUKSVETENSKAPER; AGRICULTURAL SCIENCES;

    Abstract : This thesis presents efficient systems biology modelling strategies for integrating complex multi-platform datasets in order to increase our understanding of stress biology, wood formation and secondary cell wall formation in Populus trees and connected responses to perturbations in organisms, particularly aspen. It is based on studies reported in four appended papers, designated Papers I-IV. READ MORE

  4. 7. Acetylation of polysaccharides in plant cell wall : with a focus on woody species

    Author : Prashant Mohan Pawar; Sveriges lantbruksuniversitet; Sveriges lantbruksuniversitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; LANTBRUKSVETENSKAPER; AGRICULTURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; LANTBRUKSVETENSKAPER; AGRICULTURAL SCIENCES;

    Abstract : Plant cell wall in woody tissues is a complex matrix, which consists of cellulose, matrix polysaccharides and lignin. The matrix polysaccharides are substituted with acetyl group that are hypothesised to play important roles in determining properties of these polysaccharides. READ MORE

  5. 8. Applications of molecular characters to breeding of Eucalyptus urophylla in Vietnam

    Author : Tran Ho Quang; Sveriges lantbruksuniversitet; Sveriges lantbruksuniversitet; []
    Keywords : LANTBRUKSVETENSKAPER; AGRICULTURAL SCIENCES;

    Abstract : The aim of this study was to investigate how to incorporate molecular genetics into the tree breeding program for E. urophylla. The material was a combined provenance and progeny trial, initially including 144 families from open-pollinated trees of nine provenances. READ MORE

  6. 9. Ultrastructure of the wood cell wall

    Author : Jonas Hafrén; KTH; []
    Keywords : ;

    Abstract : The ultrastructure of wood fibres has been studied incambial cells, differentiating fibres and mature xylem fibres,using the Rapid-Freeze Deep-Etching (RFDE) technique combinedwith transmission electron- and epifluorescence microscopy.Pectin distribution in mature wood fibres, and in fibres duringdevelopment, have been studied by immunolabelling.

  7. 10. Discovery of fiber-active enzymes in Populus wood

    Author : Henrik Aspeborg; KTH; []
    Keywords : Populus; xylogenesis; secondary cell wall; cellulose; hemicellulose; microarrays; transcript profiling; carbohydrate-active enzyme; glycosyltransferase; glycoside hydrolase;

    Abstract : Renewable fibers produced by forest trees provide excellentraw material of high economic value for industrialapplications. Despite this, the genes and corresponding enzymesinvolved in wood fiber biosynthesis in trees are poorlycharacterized. READ MORE
