a PdCCR1 expression and b lignin content of cell wall extracts as percentage of cell wall residue (% CWR) quantified using an acetyl bromide soluble lignin assay in P. dilatatum tissues through development. Values are average and standard errors of three biological replicates. V Vegetative stage (Ps Pseudostem, L leaf), R1 early reproductive stage, R2 late reproductive stage (I1 internode 1, I2 internode 2, I3 internode 3, L1 leaf 1, L2 leaf 2, L3 leaf 3). Asterisks indicate a significant difference (t test) relative to V stage pseudostems (P < 0.05)
