Lignin composition and acetyl bromide (AcBr) lignin content analysis in 6-week-old Arabidopsis stems from WT, fpgs1, ccoaomt1, and fpgs1ccoaomt1 plants. a Total lignin monomer yield (μmol/g AIR) determined with thioacidolysis. b Lignin monomer percentage calculated by total thioacidolysis yield. c S/G ratio of lignin monomers obtained by thioacidolysis analysis. d Total AcBr lignin content (mg/g AIR). Different letters in column indicate statistically significant differences between values according to one-way ANOVA and LSD test (values were mean ± SE. n = 3, P ≤ 0.05. Each biological replicate included mature inflorescence stems pooled from 20 individual plants)
