| Outline of Final Research Achievements |
For the highly utilization of wood biomass, we need to understand the mechanism of differentiation of secondary xylem in trees such as the process of formation of highly ordered structure of cell wall. We developed new in vitro model system that induced directly secondary xylem-like tracheary elements from cultured cells of trees such as hybrid poplar and some conifers. Tracheary elements formed highly developed structure of secondary walls, such as broad regions of thick cell walls, bordered pits and helical thicknenings. Using this model system, we analyzed the pattern of lignification in cell walls and cell corners by histochemical techniques. In addition, we analyzed the localization of microtubules using stable expression of genes for microtubule-associated proteins with green fluorescent protein. The microtubules play an important role in the determination of localization of secondary wall.
