A chromosome-level genome assembly reveals triterpenoid biosynthesis in Clinopodium chinense.

ABSTRACT:

Background

Clinopodium chinense is an important medicinal plant in the family Lamiaceae. The desiccated roots of C. chinense possess various pharmacological activities and are widely used in traditional Chinese medicine.

Results

Here we present the first chromosome-level genome assembly of C. chinense, comprising 20 pseudochromosomes with a total size of 0.61 Gb and containing 45,466 predicted protein-coding genes. Genome evolution analyses indicated that two recent bursts of long terminal repeats (LTRs) significantly contribute to genome expansion in C. chinense. Additionally, numerous large-scale chromosomal rearrangements have been identified between the genomes of C. chinense and Thymus quinquecostatus. Comparative genomics analyses further indicated that tandem duplicat
