MOESM3 of Working towards recalcitrance mechanisms: increased xylan and homogalacturonan production by overexpression of GAlactUronosylTransferase12 (GAUT12) causes increased recalcitrance and decreased growth in Populus

Additional file 3. Plant height and diameter of three-month-old P. deltoides wild-type (WT), vector control and PtGAUT12.1-OE lines. Values are mean ± SE, n = 25 for WT, n = 10–15 for vector control (V. Control-1-8) and PtGAUT12.1-OE lines (AB29.1–AB29.13). Transgenic values that are significantly different from WT and vector control lines are in bold and denoted with one star (P < 0.05) or two stars (P < 0.001), as determined by one-way analysis of variance (ANOVA) followed by Tukey’s multiple comparison test using Statistica 5.0.
