Saccharification efficiency of stem biomass from wild-type (WT) and hpCSE plants. A, C, and E, Cellulose-to-Glc conversion during limited saccharification of stems from the wild type (solid lines) and the hpCSE lines (dashed lines) without (A) and with acidic (C) and alkaline (E) pretreatments. Cellulose-to-Glc conversion was calculated based on the amounts of released Glc and the quantified amount of cellulose. B, D, and F, Relative Glc release per plant after 48 h of saccharification without (B) and with acid (D) and alkaline (F) pretreatments, normalized to the values of the wild type. Error bars indicate se. Significant differences were assessed with Student’s t test (*, 0.05 > P > 0.01; **, 0.01 > P > 0.001; and ***, P < 0.001; n = 10).
