Abstract
Peucedanum praeruptorum Dunn, a traditional Chinese medicine rich in coumarin, belongs to the Apiaceae family. A high-quality assembled genome of P. praeruptorum is lacking, which has posed obstacles to functional identification and molecular evolution studies of genes associated with coumarin production. Here, a chromosome-scale reference genome of P. praeruptorum, an important medicinal and aromatic plant, was first sequenced and assembled using Oxford Nanopore Technologies and Hi-C sequencing. The final assembled genome size was 1.83 Gb, with a contig N50 of 11.12 Mb. The entire BUSCO evaluation and second-generation read comparability rates were 96.0 % and 99.31 %, respectively. Furthermore, 99.91 % of the genome was anchored to 11 pseudochromosomes. The comparative genomic study revealed the presence of 18,593 orthogroups, which included 476 species-specific orthogroups and 1211 expanded gene families. Two whole-genome duplication (WGD) events and one whole-genome triplication (WGT) event occurred in P. praeruptorum. In addition to the γ-WGT shared by core eudicots or most eudicots, the first WGD was shared by Apiales, while the most recent WGD was unique to Apiaceae. Our study demonstrated that WGD events that occurred in Apioideae highlighted the important role of tandem duplication in the biosynthesis of coumarins and terpenes in P. praeruptorum. Additionally, the expansion of the cytochrome P450 monooxygenase, O-methyltransferase, ATP-binding cassette (ABC) transporter, and terpene synthase families may be associated with the abundance of coumarins and terpenoids. Moreover, we identified >170 UDP-glucosyltransferase members that may be involved in the glycosylation post-modification of coumarins. Significant gene expansion was observed in the ABCG, ABCB, and ABCC subgroups of the ABC transporter family, potentially facilitating the transmembrane transport of coumarins after bolting. The P. praeruptorum genome provides valuable insights into the machinery of coumarin biosynthesis and enhances our understanding of Apiaceae evolution.
