ZHANG, A., LU, F., SUN, R. & RALPH, J. (2009) Ferulate-coniferyl alcohol cross-coupled products formed by radical coupling reactions. Planta, 229, 1099-1108.
Abstract: Radical coupling reactions between ethyl ferulate (Et-FA), a simple model for feruloyl polysaccharides in planta, and coniferyl alcohol (CA), a monolignol, were studied in order to better understand the polymer cross-coupling interactions among [...]

STEWART, J. J., AKIYAMA, T., CHAPPLE, C., RALPH, J. & MANSFIELD, S. D. (2009) The Effects on Lignin Structure of Overexpression of Ferulate 5-Hydroxylase in Hybrid Poplar1. Plant Physiol., 150, 621-635.
Abstract: Poplar lignins with exceedingly high syringyl monomer levels are produced by over-expression of the ferulate 5-hydroxlase (F5H) gene driven by a cinnamate 4-hydroxylase (C4H) [...]
