Pretreatability and digestibility of shoot biomass from switchgrass transgenics. a Total glucose release after the hot-water pretreatment and co-saccharification of shoot biomass. b Total xylose release after the hot-water pretreatment and co-saccharification. The percentage values on the top of bars of transgenic lines represent the % increase of released sugar in the transgenic lines compared to the EV control. Data are presented as the mean (± SE) of nine replicates. Different letters are significantly different at p < 0.05 between lines compared by one-way ANOVA with Tukey’s test
