Recalcitrance of the lignocellulose – focus on cellulose |
 |
 |
 |
Cellulose biosynthesis will be investigated by utilising microarray and co-expression data to identify novel genes that are highly co-regulated with the cellulose biosynthetic CesA genes during tension wood formation of hybrid aspen. Arabidopsis mutants in some of these genes have revealed interesting cell wall phenotypes, suggesting that they are important parts of cellulose biosynthesis. We will analyse localization and function of these genes in Arabidopsis. We will also modify expression levels of some these genes in transgenic hybrid aspen trees for functional analysis in cellulose biosynthesis and related processes. In addition to the analysis of wood chemistry and saccharification potential, the novel lines will be analysed for the structure of cellulose and for mechanical analysis (3.5.2) in collaboration with Dr. Ingo Burgert.
