| Research Abstract |
Secondary cell walls (SCWs) of plants are important because they are major components of woody biomass. However, little is known about mechanisms underlying SCW formation. In this study, we revealed several new aspects of the mechanisms through the analysis of biosynthesis of cellulose and xylan, major constituents of SCWs, and the analysis of regulatory system of VND7, the master regulatory switch of SCW formation, by using a new in vitro SCW induction experimental system that was established with the VND7 gene.
