| Research Abstract |
Lignocellulose is the main source of renewable biomass on Earth and is an attractive feedstock. Lignin is a major component of lignocellulosic biomass, and is an obstacle in the enzymatic saccharification of plant cell wall polysaccharides. However, little is known about suprastructures of the lignocellulosic components, which affect largely the utilization of the lignocellulose. In this context, using chemical analysis, gene expression analysis, morphological observation, enzymatic saccharification etc., we have characterized lignins and related compounds of a large grass plant, Erianthus and a number of transgenic rice plants, where expression of lignin biosynthetic genes are regulated. This study provided basic information on cell wall components for future breeding programs of large grass plants and for better utilization of the lignocellulosic biomass resource.
