Chromosome-level genome assembly of an important ethnic medicinal plant Callicarpa nudiflora

Callicarpa nudiflora is one of high medicinal and economic value plants in China, which was recorded in Chinese pharmacopoeia (2020 edition) and widely used to treat tropical bacterial infections, acute infectious hepatitis, and internal and external bleeding. In this study, we assembled the C. nudiflora genome with a size of approximately 597.82 Mb and a contig N50 length of 34.14 Mb. A total of 98.61% of the assembled sequences were anchored to 17 pseudo-chromosomes by using PacBio long reads and Hi-C sequencing data. We totally predicted 31,266 protein-coding genes, of which 92.45% could be annotated in databases such as NR, GO, KOG, and KEGG. In addition, we identified 2,303 rRNAs, 884 MicroRNAs and 531 tRNAs from the genome. The chromosome-scale genome represents a crucial resource for investigating the molecular mechanisms underlying the biosynthesis of medicinal components and facilitates the exploration and conservation of C. nudiflora.
