Accurate Assembly Of The Olive Baboon (Papio Anubis) Genome Using Long-Read And Hi-C Data

Background: Baboons are a widely used nonhuman primate model for biomedical, evolutionary, and basic genetics research. Despite this importance, the genomic resources for baboons are limited. In particular, the current baboon reference genome Panu 3.0 is a highly fragmented, reference-guided (i.e., not fully de novo) assembly, and its poor quality inhibits our ability to conduct downstream genomic analyses. Findings: Here we present a de novo genome assembly of the olive baboon (Papio anubis) that uses data from several recently developed single-molecule technologies. Our assembly, Panubis1.0, has an N50 contig size of similar to 1.46 Mb (as opposed to 139 kb for Panu 3.0) and has single scaffolds that span each of the 20 autosomes and the X chromosome. Conclusions: We highlight multiple lines of evidence (including Bionano Genomics data, pedigree linkage information, and linkage disequilibrium data) suggesting that there are several large assembly errors in Panu 3.0, which have been corrected in Panubis1.0.
