From: In muro deacetylation of xylan affects lignin properties and improves saccharification of aspen wood
Transgenic trees had similar lignin content but different lignin solubility and associated sugars compared to WT. a Acetyl bromide-soluble and b dioxane-soluble lignin contents in ball milled wood (BMW). c Composition of sugars in polysaccharides co-precipitated with lignin. Lignin was extracted from BMW with acidified dioxane as described in “Methods”, and precipitated with water. The inset shows the absolute change in the Xyl content of the lignin precipitate. Data in a and c are mean ± SE, n = 3 replicates representing pooled samples of six transgenic (Trans; two trees from each lines, 8, 4, 17), or wild-type (WT) trees. Asterisks indicate means significantly different from WT, *P ≤ 0.1; **P ≤ 0.05 (ANOVA)
