Chromosome-scale Genome Assembly and Annotation of Anise Hyssop (Agastache foeniculum)

Abstract

We present a chromosome-scale genome assembly and annotation of anise hyssop (Agastache foeniculum), an aromatic perennial herb widely used for medicinal, horticultural, and ornamental purposes. The genome was assembled using PacBio HiFi long-read sequencing, Illumina short-read sequencing, and Omni-C proximity ligation data, with gene annotation supported by RNA-seq data from leaf tissue. The final assembly spans 482.39 Mb, of which 434.47 Mb (90.06%) were anchored into nine chromosome-scale pseudomolecules. Structural annotation identified 28,193 protein-coding genes. Genome completeness was assessed using BUSCO, yielding scores of 98.0% (embryophyta_odb10, genome mode) and 95.5% (protein mode). This chromosome-scale genome assembly provides a foundational genomic resource for comparative and functional genomics within the genus Agastache and the Lamiaceae family.
