This is a correction to: Jan Hellinger, Hoon Kim, John Ralph, Steven D Karlen, p-Coumaroylation of lignin occurs outside of commelinid monocots in the eudicot genus Morus (mulberry), Plant Physiology, 2022, kiac485, https://doi.org/10.1093/plphys/kiac485
In the originally published version of this manuscript, Figure 3 was incorrect. A duplicate of figure 2 had been used incorrectly instead of the correct Figure 3, which is presented here:
Chemical characterization by pyrolysis–GC–MS and DFRC confirming the presence of pCA. A, GC–MS pyrograms of Morus lignins pyrolyzed at 500°C in the presence of TMAH. Labeled peaks correspond to compounds identified and reported in Table 2. B, GC–MRM–MS chromatograms of the released products diagnostic for lignin-bound pCA (quantified as ML-DHpCA) with MRM transitions: G-DHpCA 370 > 131 m/z and S-DHpCA 400 > 161 m/z, and lignin-bound FA (quantified as DHFA) with MRM-transition G-DHFA 358 > 163 m/z. C, Schematic for the DFRC lignin depolymerization process. D, ML pCA abundance as determined by DFRC (detected as G-DHpCA and S-DHpCA then converted to G-pCA and S-pCA), and the calculated amount of lignin-bound pCA as determined from the DFRC product mixture. Error bars indicate Sem for n = 2 technical replicates.
