MOESM4 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 4. Correlation between the total GAUT12.1 transcript expression and plant growth in P. deltoides PtGAUT12.1-OE transgenic and control lines. a Height and b radial diameter of 3-month-old greenhouse-grown poplar plants are plotted against the transcript expression level. Blue diamonds—WT; black diamonds—vector controls; red diamonds—PtGAUT12.1-OE lines (please note that on the graphs the WT blue diamonds may be obscured by the vector control black diamonds). n = 25 for WT, n = 10–15 for vector control and PtGAUT12.1-OE lines.
