Lignin-derived monomers (H, G, S) after thioacidolysis of dry aerial parts from control Ws and null cyp98A3 mutant

The data represent the mean value (se in brackets) of duplicate analyses. Stems/leaves from 6-week-old null plants (grown on soil) or 3-week-old roots (plate grown) were collected and compared to samples either from similarly sized Ws plants or from similarly aged Ws plants.
