Abstract

Heliocidaris crassispina is a tropical sea urchin that holds both ecological and economic value and serves as an ideal experimental animal. This study first employed a combination of PacBio HiFi and Hi-C sequencing data to present a high-quality, chromosome-level assembly of H. crassispina genome. This assembled genome spanned 709.77 Mb, with a contig N50 length of 4.98 Mb and a scaffold N50 length of 33.23 Mb. The assembly was anchored on 21 pseudo-chromosomes, covering 98.32% of the genome. A total of 18,665 protein-coding genes were identified, and BUSCO analysis revealed a completeness score of 97.1%. Additionally, non-coding RNAs (ncRNAs) were annotated, including miRNAs, rRNAs, tRNAs and snRNAs, providing a more complete functional understanding of the genome. The high-quality reference genome will enrich the current echinoderm genomic resources and provide a solid foundation for future studies on H. crassispina, including resource surveys, genomic breeding, and marine ranch management.

期刊介绍： Scientific Data is an open-access journal focused on data, publishing descriptions of research datasets and articles on data sharing across natural sciences, medicine, engineering, and social sciences. Its goal is to enhance the sharing and reuse of scientific data, encourage broader data sharing, and acknowledge those who share their data. The journal primarily publishes Data Descriptors, which offer detailed descriptions of research datasets, including data collection methods and technical analyses validating data quality. These descriptors aim to facilitate data reuse rather than testing hypotheses or presenting new interpretations, methods, or in-depth analyses.
