Abstract
Cellulose, a major component of the cell walls, is the most abundant biopolymer in plants and serves many uses as industrial materials. However, the cellulose synthesis is so complicated that the mechanisms are poorly understood. In the present study, we analyzed a comprehensive gene coexpression profiles of the cell wall formation-related genes based on the publicly available microarray data sets from RIKEN and the Max Planck Institute.
The cellulose synthase genes (CesA) involved in primary and secondary cell wall formation were classified into two separate groups. In these groups, genes that have been previously shown to participate in cell wall formation, such as COBRA and chitinase-like protein gene, were correlated with CesA. Additionally, CesA also correlated with genes encoding enzymes and transcription factors that have been uncharacterized so far. These genes may participate in and play distinct roles in the formation of primary and secondary cell wall.
