Chromosome-level genome assembly and annotation of the Patagonian toothfish Dissostichus eleginoides.
The Patagonian toothfish (Dissostichus eleginoides) belongs to the Actinopterygii class, and the suborder Notothenioidei, which lives in cold waters in the Southern Hemisphere. We performed assembly and annotation, and we integrated the Illumina short-read sequencing for polishinng, PacBio long-read sequencing for contig-level assembly, and Hi-C sequencing technology to obtain high-quality of chromosome-level genome assembly. The final assembly analysis resulted in a total of 495 scaffolds, a genome size of 844.7 Mbp and an N50 length of 36 Mbp. Among these data, we confirmed 24 scaffolds exceeded 10 Mbp and classified as chromosome-level. The completeness of BUSCO rate was over 97%. A total gene set of 32,224 was identified. Furthermore, we analyzed the presence of AFGP genes, classified into Antarctic and sub-Antarctic categories through phylogenetic analysis. This study provides a useful resource for the genomic analysis of Patagonian toothfish and genetic insights into the comparison with Antarctic fishes.
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.
