Schematic illustration of the structure of different plant cell wall polysaccharides along with the associated reactions and genes in the PCWDN of N. crassa. Cellulose has an unbranched structure composed of linear chains of β-1,4-linked d-glucose residues. Hemicellulose comprises several branched polymers including xylan, xyloglucan (XG), mannan, and mixed-linkage glucan (MLG). Pectin is a family of several polymers including homogalacturonan, xylogalacturonan, and rhamnogalacturonan I. Starch is a polymer composed of amylose and amylopectin. On the right, the number of reactions and genes involved in the degradation of cellulose, hemicelluloses, pectin, and starch are indicated that are captured in our PCWDN
