 Prof. Björn Sundberg, Swedish University of Agricultural Sciences

The group, in close collaboration with P3, SweTreeTechnologies, will produce transgenic poplars potentially modified in cellulose and matrix structure. Cell walls of wood fibres will be analysed using microscopy, spectroscopy and mass spectrometry by in-house technology and also be made available for the consortium partners.

Umea Plant Science Centre is a world-leading centre in forest biotechnology. UPSC have established all platforms required for state of the art work in functional genomics. The groups of UPSC have significantly contributed to establishing poplar as a model species for forest trees by sequencing 100,000 ESTs and developing a poplar microarray now with 20,000 unique ESTs. Moreover, databases for poplar metabolites and proteins are currently being established by the metabolomics and proteomics platforms. The expertise and research focus of the group is in wood biology. The proposed research is well in line with the interest of the group members and UPSC research profile.
