 Contributed by aracyc:
Lignin is a three dimensional polymer of phenylpropanoid alcohols (monolignols). Lignin is always associated with cell wall cellulose and hemicellulose, and provides mechanical rigidity to plant-supporting and plant-conducting tissues. There are three monolignols, p-coumaryl alcohol, coniferyl alcohol, and sinapyl alcohol. The relative amounts of these monolignols found in lignin show plant specificity. Gymnosperm lignins contain mainly coniferyl alcohol, angiosperm lignins contain both coniferyl alcohol and sinapyl alcohol, whereas all three types of monolignols are found within lignins of grasses. The transport of monolignols to the cell wall and their lignification to lignin is poorly understood. These events possibly involve glucosylation. Lignification is possibly catalyzed by peroxidase. In the past decade, the lignin biosynthesis pathway has been redrawn several times based on new genetic and biochemical evidences. The pathway depicted here only illustrates the major routes to lignin monomers.
  Parts of this pathway occur in:   cytosol     nucleus     endoplasmic reticulum     peroxisome
