The molecular weights and glycosyl residue composition of the hemicellulose fractions from switchgrass. Number-average (Mn) and weight-average (Mw) molecular weights of the alkaline-extracted hemicellulose-enriched fractions isolated from GAUT4-KD (2A, 2B, and 4A) lines and wild-type (WT) control. Ara: arabinose; Rha: rhamnose; Xyl: xylose; GalA: galacturonic acid; Man: mannose; Gal: galactose; Glc: glucose. *p value <0.05 and **p value <0.001 by Student’s t test of biologically duplicate values
