Table 1 Lignin content and monomer composition in WT and CWPO-C transgenic poplar

	Lignin (%)			µmol S/g lignin			µmol G/g lignin			S/G			µmol (S + G)/g lignin
WT	9.2	±	0.8	61	±	20	428	±	40	0,14	±	0,03	489	±	60
RNAi1	5.1	±	0.6^b	51	±	14	717	±	81^b	0,07	±	0,01^a	768	±	93^b
OE1	8.8	±	0.9	45	±	14	381	±	74	0,12	±	0,03	426	±	84

Lignin content and monomer composition were measured by derivatization followed by reductive cleavage (DFRC). Lignin contents are presented as percentage of cell wall dry weight. Data presented as mean ± standard deviation from four independent biological replicates. Letters indicate significant differences between transgenic line and WT control
