Specialized (iso)eugenol 4-O-methyltransferase (s-IEMT) enzymes having increased capacity for methylation of monolignols are disclosed. The s-IEMTs have unique activity favoring methylation of coniferyl alcohol versus sinapyl alcohol. Various s-IEMTs methylate ferulic acid. Means for producing the various s-IEMTs are provided. The s-IEMTs are useful for modification of lignin content and production of aromatic compounds.
