Described are polynucleotides encoding agmatine coumaroyl transferase (ACT) which catalyzes the first step in the biosynthesis of antimicrobial hydroxycinnamoylagmatine derivatives. Furthermore described are recombinant nucleic acid molecules and vectors containing these polynucleotides and host cells, preferably plant cells, being genetically modified with these polynucleotides as well as ACT polypeptides and antibodies specifically recognizing the polypeptide. In addition, transgenic plants are described showing an increased or reduced ACT activity, preferably leading to an increased pathogen resistance when ACT activity is increased and/or to an altered cell wall composition when ACT activity is altered. Moreover, methods are described for producing antimicrobial compounds or precursors thereof as well as methods for producing biopolymers by the help of ACT.
