Table 2. Lignin Monomeric Composition Determined by Thioacidolysis in Inner- and Outer-Stem Tissues of Flax lbf1 Mutants and Wild-Type Plants.

	Outer Tissues		Inner Tissues
	Wild Type	lbf1	Wild Type	lbf1
H	1.14 ± 0.45	3.33 ± 2.07	3.11 ± 0.82	2.96 ± 0.70
G	10.10 ± 5.80	26.60 ± 10.31	243.37 ± 41.09	243.05 ± 28.09
S	3.25 ± 1.34	6.94 ± 2.64	49.02 ± 3.73	32.85 ± 7.98
S/G	0.34 ± 0.05	0.26 ± 0.11	0.20 ± 0.03	0.13 ± 0.02
S+G	13.35 ± 7.14	35.03 ± 11.53	292.39 ± 42.14	275.90 ± 33.73
S+G/lignin	329.90 ± 203.75	301.49 ± 81.87	872.00 ± 79.94	968.70 ± 147.75

H, G, S = yields of the thioethylated products of p-hydroxyphenyl (H), guaiacyl (G), and syringyl (S) lignin units expressed as μmoles per gram of CWR. S/G = ratio of G to S lignin units. S+G = total S plus G lignin units expressed as μmoles per gram of CWR. S+G/lignin = yields of total lignin (S+G) expressed as μmoles per gram of lignin. For lbf1, values represent the mean values obtained with 16 and 33 individual plants for inner and outer tissues, respectively. For the wild type, inner and outer values are the mean ± sd from three individual plants. Values significantly different from the wild type at P < 0.05 are indicated in bold.
