Fig. 3From: Evaluation of engineered low-lignin poplar for conversion into advanced bioproductsLignin and 3,4-dihydroxybenzoate (DHB) contents in WT and QsuB poplar biomass at two different harvests. (A) Total lignin content expressed as a percentage (w/w) of extracted material. (B) DHB content in woody biomass. DW: dry weight. Error bars represent the standard error of three technical replicates conducted on a biomass pool from eight plants. Asterisks indicate significant differences from the WT using the unpaired Student's t-test (*p < 0.05; **p < 0.01)Back to article page
