Saccharification efficiency of OXPdDUF266A transgenic plants. Dried Populus stem was used for this analysis. a Glucose release. b Xylose release. X axis denotes enzymatic hydrolysis times in (a) and (b). c Total sugar release at 72-h enzymatic hydrolysis. Shown are mean values of two biological replicates ± standard deviation. Asterisks indicate statistical significance (p < 0.01)
