| General Description | 1. The brown midrib2 (bm2) mutant of maize displays a reddish-brown coloration of the vascular tissue in the leaf and stem, which becomes first visible at the four-leaf stage. |
| Organ Specificity | |
| Impact on Wall | 1. bm2 mutant has reduced amounts of di- and trimeric lignin derivatives, notably species with m/z 272 and m/z 330, 2. The ratio of guaiacyl residues to polysaccharides is reduced in the bm2 mutant. |
