The gradual establishment of complex coumarin biosynthetic pathway in Apiaceae.

ABSTRACT: Complex coumarins (CCs) represent characteristic metabolites found in Apiaceae plants, possessing significant medical value. Their essential functional role is likely as protectants against pathogens and regulators responding to environmental stimuli. Utilizing genomes and transcriptomes from 34 Apiaceae plants, including our recently sequenced Peucedanum praeruptorum, we conduct comprehensive phylogenetic analyses to reconstruct the detailed evolutionary process of the CC biosynthetic pathway in Apiaceae. Our results show that three key enzymes - p-coumaroyl CoA 2'-hydroxylase (C2'H), C-prenyltransferase (C-PT), and cyclase - originated successively at different evolutionary nodes within Apiaceae through various means of gene duplications: ectopic and tandem duplications.
