Anser indicus Genome sequencing and assembly
Bar-headed goose (Anser indicus) mainly inhabit on the plateau wetlands of Asia. As a specialized species native to high altitude, Bar-headed geese can migrate between South and Central Asia and fly twice annually over the Himalayan mountains along the central Asian flyway. The physiological, biochemical and behavioral adaptations of Bar-headed geese to high-altitude living and flying have been the subject of much interest. However, to date, there is still no genome sequence information publicly available for Bar-headed geese. In this study, we present the first de novo whole genome sequencing and assembly of the Bar-headed geese, along with gene prediction and annotation. 10 X Genomics sequencing produced a total of 124 Gb sequencing data, which can cover the estimated genome size of Bar-headed geese for 103 times. The genome assembly comprised 10,528 scaffolds, with a total length of 1.143 Gb and a scaffold N50 of 10.09 Mb. Annotation of the Bar-headed geese genome assembly identified a total of 102 Mb (8.9%) of repetitive sequences, 16,428 protein-coding genes and 282 tRNAs. We anticipate that these data will provide a valuable resource for future investigation of the genetic adaptation of Bar-headed geese to high altitude.
