Cell wall degradation after saccharification. Stem material after 48 h of saccharification (including acid pretreatment). (A) Wild-type. The structure of stem segments of the mutants c4h-2 (B), ccr1-3 (C), and ccr1-6 (D) are fully degraded as a consequence of the almost complete conversion of cellulose into glucose. Although the cellulose conversion was also improved in other mutants, such as c4h-3 (E) and 4cl1-1 (F), the stem structure remained intact. Scale bar = 2 mm.
