  1. *Internode 3 were collected from each transgenic and WT plants grown in soil for 5 months, six tillers were collected for each replicate. Total lignin content = S + G + H monomer content. Values are means ± SE (n = 6). The significance of treatments was tested at the P < 0.05 level (one way ANOVA, Dunnett’s test).
