Table 1 Analysis of lignin monolignols and interunit linkage in OXPdWND3A transgenic plants. Structural information of lignin was obtained by 2D 1H-13C HSQC NMR analysis. The contents of monolignols (S and G), PB (p-hydroxybenzoate), and lignin interunit linkage [β-aryl ether (β-O-4), phenylcoumaran (β-5), and resinol (β-β)] were calculated as a fraction of total lignin subunits (S + G). Two biological replicates of stem tissues were used for the analysis. The number in parenthesis displayed standard deviation
