Saccharification of cell wall residues (CWR) obtained from biomass of switchgrass lines containing the pShOMT::QsuB construct. A line containing the pShOMT::GUS construct was used as control. Amounts of sugars released from CWR after a hot water pretreatment and 72 h of enzymatic digestion with cellulase are shown. Values are means ±SE of four biological replicates (n = 4). Asterisks indicate significant differences from the control using the unpaired Student’s t-test (*P < 0.05)
