Description
Summary:•Uronic acids-rich wall polymers positively affect biomass saccharification.•Uronic acids of AO-extracted components play a major role in biomass digestion.•Uronic acids negatively affect lignocellulose CrI for high biomass digestibility.•Potential modification of uronic acids-rich polymers in bioenergy Miscanthus. Based on systems biology analyses of total 179 representative Miscanthus accessions, ammonium oxalate (AO)-extractable uronic acids could either positively affect biomass digestibility or negatively alter lignocellulose crystallinity at p
