Cell wall composition and saccharification efficiency of T2 generation B. distachyon plants down-regulated in HCT1 or HCT1 and HCT2. a-d show data for individual lines on the left, means and standard deviations for the group on the right. a Total lignin as determined by thioacidolysis (see Figure S6 for monomer composition). b Cell wall-bound 4-coumaric and ferulic acids. c Total sugar content of cell wall residues in mg glucose equivalents. d Saccharification efficiency of cell wall residues, based on enzymatic sugar release without pretreatment relative to the total available cell wall sugar. Right hand panels show relationship between saccharification efficiency and lignin content (e), S/G (f) and H/T (g) monomer ratios. Asterisks indicate statistically significant differences (P < 0.05)
