The sequence and de novo assembly of Oxygymnocypris stewartii genome

Abstract

Animal genomes in the Qinghai-Tibetan Plateau provide valuable resources for scientists to understand the molecular mechanism of environmental adaptation. Tibetan fish species play essential roles in the local ecology; however, the genomic information for native fishes was still insufficient. Oxygymnocypris stewartii, belonging to Oxygymnocypris genus, Schizothoracinae subfamily, is a native fish in the Tibetan plateau living within the elevation from roughly 3,000\u2009m to 4,200\u2009m. In this report, PacBio and Illumina sequencing platform were used to generate ~385.3\u2009Gb genomic sequencing data. A genome of about 1,849.2\u2009Mb was obtained with a contig N50 length of 257.1\u2009kb. More than 44.5% of the genome were identified as repetitive elements, and 46,400 protein-coding genes were annotated in the genome. The assembled genome can be used as a reference for future population genetic studies of O. stewartii and will improve our understanding of high altitude adaptation of fishes in the Qinghai-Tibetan Plateau.Design Type(s)sequence analysis objective • sequence annotation objective • sequence assembly objective • transcription profiling designMeasurement Type(s)whole genome sequencing • transcription profiling assayTechnology Type(s)DNA sequencing • RNA sequencingFactor Type(s)Sample Characteristic(s)Oxygymnocypris stewartii • muscle tissue • ovary • gut wall • kidney • adipose tissue • eye • swim bladder • skin of body • liver • heart • gill • brain • Tibetan Plateau • riverMachine-accessible metadata file describing the reported data (ISA-Tab format)
