Fig. 3From: Expression of a bacterial 3-dehydroshikimate dehydratase (QsuB) reduces lignin and improves biomass saccharification efficiency in switchgrass (Panicum virgatum L.)Protocatechuate (PCA) content measured in the biomass of switchgrass pShOMT::QsuB transgenic lines. Values are means ±SE of three biological replicates (n = 3). Asterisks indicate significant differences from a line containing the pShOMT::GUS construct using the unpaired Student’s t-test (*P < 0.05)Back to article page
