My research interest is within the development and biosynthesis of secondary xylem (wood) formation. My current aim is to translate know-how about the molecular regulation of industrial important traits such as wood biomass, fibre morphology, -ultrastructure and -chemistry into biotechnology solutions for operational forestry and industrial biorefining.

We are using in vitro grown aspen trees as an experimental system to perform pharmacological experiments and for initial screening of wood properties. Picture modified from PNAS 2009 106: 5984-5989. | Tension wood is formed in leaning stems. The fiber cell wall (A) forms a normal S2 layer, but has an inner wall layer of almost pure cellulose (G), without lignin and hemicelluloses. Individual cellulose microfibrils are seen in B. Picture modified from Current Opinion Plant Biology 2008 11: 293-300 was generously provided by Prof. Geoffrey Daniel, SLU Uppsala. |
