Haplotype-resolved chromosome-level genome sequence of Elsholtzia splendens (Nakai ex F.Maek.)

Elsholtzia splendens, a perennial herb native to East Asia, is valued for its ornamental and medicinal uses, particularly in treating inflammatory and febrile conditions. Recent studies have highlighted its antibacterial, anti-inflammatory, antidepressant, antithrombotic, and lipid-lowering properties of its compounds. Additionally, E. splendens shows potential for phytoremediation owing to its ability to hyperaccumulate copper (Cu), lead (Pb), zinc (Zn), and cadmium (Cd). However, its role in remediation conflicts with its medicinal use because of the risk of heavy metal accumulation. Genome sequencing will be key to boosting beneficial compound production and reducing heavy metal risks. In this study, we generated a high-resolution, haplotype-resolved, chromosome-scale genome sequence of E. splendens using PacBio Revio long-read, Illumina short-read, and Hi-C sequencing technologies. The haplotype genome assemblies, spanned 275.4 and 265.0 Mbp with a scaffold N50 of 33.9 and 33.8 Mbp for haplotype 1 and 2, respectively. This assembly provides valuable insights into medicinal compound biosynthesis and supports genetic conservation efforts, facilitating future genetic and biotechnological applications of E. splendens for medicinal and ecological uses.
