Abstract excerpt

Previous studies have indicated that the Arabidopsis thalianairregular xylem 4 (irx4) mutant is severely lignin-deficient, forming abnormal lignin from aberrant monomers. Studies of lignin structure in dwarfed cinnamoyl CoA reductase (CCR)-downregulated tobacco were also previously reported to incorporate feruloyl tyramine derivatives. The lignin in the Arabidopsis irx4 mutant was re-investigated at 6 weeks and...
