S = syringyl lignin, G = guaiacyl lignin, 35S = cauliflower mosaic virus promoter, COMTa = caffeic acid-O-methyltransferase from Populus trichocarpa × deltoides, C4H = cinnamate-4-hydroxylase promoter from Arabidopsis thaliana, F5H = ferulate 5-hydroxylase from Arabidopsis thaliana, F5H2 = ferulate 5-hydroxylase 2 from Populus trichocarpa, RNAi = RNA interference
