  1. Lignin content is expressed in % (w/w). Sugar content is expressed in μg/mg of wood de-starched alcohol-insoluble residue (AIR). Means ± standard error, n = 10 or 2 biological replicates for lignin and sugars, respectively.
  2. 1Averages for the transgenic lines in bold are significantly different from wild-type (WT) (post analysis-of-variance (ANOVA) t-test). Averages for WT in bold are significantly different from both transgenic lines taken together (post-ANOVA contrast). *P ≤10%; **P ≤5%.
