The sequence and de novo assembly of the wild yak genome

In this study, we sequenced and de novo assembled its genome. A total of six different insert-size libraries were sequenced and generated 662 Gb of clean data in total. The assembled wild yak genome is 2.83 Gb in length, with an N50 contig size of 63.2 kb and a scaffold size of 16.3 Mb. BUSCO assessment indicated that 93.8% of the highly conserved mammal genes were completely present in the genome assembly. Annotation of the wild yak genome assembly identified 1.41 Gb (49.65%) of repetitive sequences and a total of 22,910 protein-coding genes, among these genes, 20,660 (90.18%) are annotated with functional terms.
