| Research Abstract |
For wood utilization, some of the properties are often affected by the chemical compounds contained in the wood. In the case of Japanese cedar ; sugi, the compounds called norlignan in the heartwood(=dark part of trunk, etc) are considered to control wood color or durability. In this research, we were able to characterize one of the enzymatic reaction in norlignan production(=biosynthesis) in sugi tree, to propose the mechanism of norlignan change toward sugi wood color expression after the biosynthesis, and to elucidate the chemical structure of the changed product. Furthermore, we analyzed the gene expression associated with biological reactions(initiation factor, etc) during sugi heartwood formation involving norlignan biosynthesis.
