Variation of lignin and carbohydrate contents in transgenic and wildtype P. trichocarpa. a lignin, b glucose, c xylose, d mannose, and e galactose contents, and the carbohydrate to lignin (C:L) ratio f in the wood of transgenic (red bars) and wildtype (black bars) P. trichocarpa. See Supplementary Data 3. g Lignin and total carbohydrate contents are negatively correlated. The negative linear relationship has a slope of −0.8 and a correlation coefficient of −0.4. Each data point represents a replicate pool of one wildtype or transgenic line containing 3–5 clonally propagated trees
