Correlations between the wall polymers and the biomass saccharification in transgenic rice straws (n = 247). a Correlation between cellulose levels and yields of sugars (pentoses, hexoses) released from both pretreatment and enzymatic hydrolysis. b Correlation between hemicellulose features and yields of sugars released. c Correlation between lignin features and yields of sugars released. Ara arabinose, Xyl xylose, X/A xylose/arabinose, ASL acid-soluble lignin, AIL acid-insoluble lignin. * and ** indicate significant correlations at the p < 0.05 and 0.01 levels
