Determination of p-coumaric acid (CA) and ferulic acid (FA) released by mild alkaline hydrolysis of extract-free mature culms from Brachypodium wild type and laccase mutants

Line	CA mg/g	FA mg/g
WT	6.01 ± 0.22	5.24 ± 0.26
lac5	5.71 ± 0.51	7.86 ± 0.18*
lac8	5.08 ± 0.19*	5.88 ± 0.03*
lac5 lac8	4.81 ± 0.39*	12.99 ± 0.50*

Data are mean values and standard errors from biological triplicates. Asterisks denote significant differences (one-way ANOVA test) relative to the control value at P < 0.05
