Lignins are assembled from monolignols, which are synthesized via the shikimate and phenylpropanoid pathways. Mutants in which the lignin biosynthetic genes are affected have been identified in several species.
Hydroxycinnamic acids, which originate from the deamination, hydroxylation and sometimes methylation of phenylalanine (and tyrosine in grasses), are commonly incorporated into type II walls.
