Plants produce around 300 aromatic compounds enzymatically linked to prenyl side chains via C-O bonds, some of which can impact human health. The discovery of aromatic O-PT genes in plants like grapefruit and Angelica keiskei sheds light on the evolution of plant secondary metabolites. Phylogenetic analysis suggests that aromatic O-prenylation activity evolved independently from the same ancestral gene in distant plant taxa.
Plants produce ?300 aromatic compounds enzymatically linked to prenyl side chains via C?O bonds. These O-prenylated aromatic compounds have been found in taxonomically distant plant taxa, with some of them being beneficial or detrimental to human health. Although their O-prenyl moieties often play crucial roles in the biological activities of these compounds, no plant gene encoding an aromatic O-prenyltransferase (O-PT) has been isolated to date. This study describes the isolation of an aromatic O-PT gene, CpPT1, belonging to the UbiA superfamily, from grapefruit (Citrus ? paradisi, Rutaceae). This gene was shown responsible for the biosynthesis of O-prenylated coumarin derivatives that alter drug pharmacokinetics in the human body. Another coumarin O-PT gene encoding a protein of the same family was identified in Angelica keiskei, an apiaceous medicinal plant containing pharmaceutically active O-prenylated coumarins. Phylogenetic analysis of these O-PTs suggested that aromatic O-prenylation activity evolved independently from the same ancestral gene in these distant plant taxa. These findings shed light on understanding the evolution of plant secondary (specialized) metabolites
