1. Understanding and manipulating primary cell walls in plant cell suspension cultures
Abstract : The cell wall is required for many aspects of plant function and development. It is also an accessible and renewable resource utilized both in unrefined forms and as raw material for further development. Increased knowledge regarding cell wall structure and components will contribute to better utilization of plants and the resources they provide. READ MORE

2. Composition of lignin in outer cell-wall layers
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

3. Interactions between Wood Polymers in Wood Cell Walls and Cellulose/Hemicellulose Biocomposites
Abstract : A wood fibre is a complex multi component biocomposite that is hierarchically organised. The arrangement of a wood fibre on the ultrastructural level is highlycontrolled by the interactions between the main structural polymers, i.e. cellulose, various hemicelluloses and lignin, as well as in some parts also pectin and protein.

4. Ultrastructure of the Primary Cell Wall of Softwood Fibres Studied using Dynamic FT-IR Spectroscopy
Abstract : The primary cell wall is a complex multipolymer system whose composite structure has been mostly determined from chemical and biochemical studies. Although the primary cell wall serves a central role, with regard to the connective properties of fibres, knowledge about the interactions among the polymers, when it comes to the mechanical properties, is very limited.

5. Ultrastructure of the wood cell wall
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.
