White eared pheasant (WT), (Crossoptilon crossoptilon), inhibiting at high altitudes (3000~4,300 m), is a Galliformes bird native to the Qinghai, Sichuan, Yunnan and Tibet Province of China. Due to the difficulty of sequencing the precious species, there is no high-quality genome assembly for the species, hampering the understanding of their genetic mechanisms. To fill the gap, we sequenced and assembled a WT individual using Illumina short reads, PacBio long reads and Hi-C reads. With a contig N50 of 19.63 Mb, scaffold N50 of 29.59 Mb, total length of 1.02 Gb and BUSCO completeness of 97.2%, the assembly is highly complete. Evaluation shows that the assembly is at chromosome-level with only six gaps. Thus, our assembly provides a valuable genetic resource for the crossoptilon species. To further provide resources for gene annotation and population genetics analysis, we also sequenced transcriptomes of 20 tissues of the WT individual and re-sequenced another 10 individuals of WT. Our assembled WT genome and the sequencing data can be valuable resources to study the crossoptilon species.
