Fig. 6From: Overexpression of PtoMYB115 improves lignocellulose recalcitrance to enhance biomass digestibility and bioethanol yield by specifically regulating lignin biosynthesis in transgenic poplarComparison of lignocellulose features between the PtoMYB115 transgenic lines and WT. a Degree of polymerization (DP) of crude cellulose; b cellulose accessibility by measuring Congo red (CR) dye area; c glucose yield of the cellobiose released from time-course CBHI hydrolyzes using crude cellulose as substrate; d correlation analysis between lignocellulose features and hexose yields (% biomass) released from enzymatic hydrolyses after NaOH pretreatment. All data are means ± SD of three technical replicates. **Significant correlation at P < 0.01 (n = 3 in a–c, n = 15 in d)Back to article page
