Aliphatic (a) and aromatic (b) regions of 1H-13C HSQC NMR spectra of untreated and 7 days P. anserina-treated wheat straw lignin water-insoluble residues. Unassigned signals are shown in gray. Colored boxes show semiquantitative analysis of the volume integrals, with interunit linkages per 100 subunits (aromatic rings, Ar), relative distribution of subunits (%) and T, pCA and FA relative to total subunits (%). Dotted lines represent –H or –OCH3. Wavy lines indicate main positions for further coupling. Unassigned signals are shown in gray
