Lignin content of extract-free mature culms from Brachypodium wild type and laccase mutants

Line	KL %	ABL %
WT	18.29 ± 0.09 (100)	20.85 ± 0.27 (100)
lac5	16.37 ± 0.10 (89)*	19.50 ± 0.50 (93)*
lac8	16.52 ± 0.22 (90)*	19.11 ± 0.42 (92)*
lac5 lac8	12.10 ± 0.04 (66)*	16.78 ± 0.46 (80)*

The Klason lignin (KL) and the acetyl bromide lignin (ABL) contents are expressed as weight percentage of extract-free samples. Data are mean values and standard errors from biological triplicates. Values between brackets are the percentages relative to the control level. Asterisks denote significant differences (one-way ANOVA test) relative to the control value at P < 0.05
