The abundance of the monolignol biosynthetic gene transcripts and proteins in transgenic P. trichocarpa lines. a Relative abundance of PtrPAL1 transcripts in the transgenic and wildtype P. trichocarpa. White bars represent PtrPAL1 transcript abundance in wildtype trees. Striped bars represent PtrPAL1 transcript abundance in transgenic lines targeting the downregulation of PtrPAL1. Gray bars represent PtrPAL1 transcript abundance in transgenic lines targeting the downregulation of both PtrPAL1 and PtrPAL3. Black bars represent PtrPAL1 transcript abundance in transgenic lines targeting the downregulation of all five PtrPALs. b The x-axis represents the genotypes of the transgenic lines, and the y-axis represents relative transcript (black bars) and protein (gray bars) abundance to the average wildtype level. Error bars represent the standard error of at least three biological replicates
