Overexpression of PtxtPL1-27 affects extractability of acidic polymers from wood. Wood alcohol-insoluble residues (AIRs) were sequentially extracted with water, 1,2-cyclohexylenedinitrilotetraacetic acid (CDTA) 1 M potassium hydroxide (KOH) and 4 M KOH, and the amounts of uronic acids extracted by each solvent and remaining in the pellet was determined by the biphenyl assay and expressed per weight of extracted cell wall material. Data are means of three biological replicates and standard error. Probability refers to the post analysis-of-variance analysis by contrast between transgenic lines and wild-type (WT).
