In this study, a haplotype-resolved chromosome-scale genome assembly for Coriaria nepalensis was obtained using PacBio HiFi sequencing and Hi-C scaffolding techniques. The assembly has a size of approximately 620 Mb with a contig N50 of 11 Mb and 99.9% of the sequences anchored to 40 pseudochromosomes. A total of 60,862 protein-coding genes, 939 tRNAs, 7,297 rRNAs, and 982 ncRNAs were predicted. This chromosome-scale genome provides a valuable resource for studying the genetic basis of root nodulation with Frankia, toxicity, and tannin biosynthesis in C. nepalensis.
Coriaria nepalensis Wall. (Coriariaceae) is a nitrogen-fixing shrub which forms root nodules with the actinomycete Frankia. Oils and extracts of C. nepalensis have been reported to be bacteriostatic and insecticidal, and C. nepalensis bark provides a valuable tannin resource. Here, by combining PacBio HiFi sequencing and Hi-C scaffolding techniques, we generated a haplotype-resolved chromosome-scale genome assembly for C. nepalensis. This genome assembly is approximately 620 Mb in size with a contig N50 of 11 Mb, with 99.9% of the total assembled sequences anchored to 40 pseudochromosomes. We predicted 60,862 protein-coding genes of which 99.5% were annotated from databases. We further identified 939 tRNAs, 7,297 rRNAs, and 982 ncRNAs. The chromosome-scale genome of C. nepalensis is expected to be a significant resource for understanding the genetic basis of root nodulation with Frankia, toxicity, and tannin biosynthesis.
