Lignin is an essential component of plant cell walls, but it is not a storage material. The characteristics present obstacles to enzymatic hydrolysis of lignocellulosic polysaccharides for biorefinery. Herein, we identified factors that control secondary cell wall formation and manipulated expression of genes encoding the factors. Analysis of the transgenic plants thus obtained indicated that they had lower lignin contents and thatthe lignin structures and amounts affected largely the enzymatic saccharification efficiency. This provides useful information on future molecular breeding of lignocellulosic materials for biorefinery.
