Normalized total ion current chromatograms displaying the content of esterified p-coumaric (pCA) and ferulic acid (FA) in the cell walls of wild-type and bmr stover as determined by pyrolysis-TMAH-GC-MS. (A) BTx623 (wild-type). (B) bmr29. (C) bmr30. (D) bmr31. (E) bmr-32-1. (F) bmr32-2. The peaks representing the double methylesters of (1) trans-p-coumaric acid (m/z 192) and (2) trans-ferulic acid (m/z 222) have been selectively displayed. The ratio of the peak areas (pCA/FA) is displayed. This ratio is not reflective of the actual molar ratio of pCA and FA in the cell wall due to the differences in sensitivity of detection.
