Abstract
Big-barbel schizothorcin (Schizothorax macropogon), an endemic and vulnerable species to the mid-reaches of the Yarlung Zangbo River, epitomizes survival in harsh conditions yet suffers significant population contractions due to human activities. This species was the subject of our study in which we leveraged PacBio, MGI-Seq, and Hi-C data to assemble a chromosome-scale genome. This assembly comprises 25 pseudo-chromosomes, yielding a genome size of 1.42 Gb with a scaffold N50 length of 59.4 Mb, indicative of a highly contiguous assembly. A BUSCO assessment ascertained the comprehensiveness of the genome at 97.9%. Annotation efforts identified 46,246 putative protein-coding genes, with 49.61% of the assembled genome annotated as repetitive sequences. This genome assembly is instrumental for advancing conservation of the giant whiskered schizothoracines and related species, and for illuminating the evolution and ecology of schizothoracine fishes in the Qinghai-Tibet Plateau.
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.
