Squirrel monkey (Saimiri boliviensis)

Black capped or Bolivian squirrel monkeys are a squirrel monkey species found in Bolivia, Brazil and Peru. In German, squirrel monkeys are called Totenkopfaffen (skull monkeys) for their distinctive black-and-white faces. Read more about squirrel monkeys in Wildscreen Arkive.

Chromosome-length genome assembly

Download the saiBolDis_HiC.fasta.gz file containing the chromosome-length (2n=44) assembly of the squirrel monkey genome. All modifications with respect to the draft (see below) are annotated in the saiBolDis_HiC.assembly file. Some basic stats associated with the new reference, saiBolDis_HiC, are listed below. The full data release can be explored here.

Draft

The chromosome-length genome assembly is based on the draft assembly saiBolDis, credited below.

This assembly was generated by the DNA Zoo team in collaboration with Jessica Alfoldi, Broad Institute, using an early version of DISCOVAR de novo contigger.

Method

3D Assembly was performed using 3D-DNA pipeline (Dudchenko et al., Science, 2017). The genome was reviewed using Juicebox Assembly Tools  (Dudchenko et al., bioRxiv, 2018). See Methods for more information.

Hi-C sample

The primary sample for in situ Hi-C preparation was donated by a female individual, and provided to us by Jessica Alfoldi, Broad Institute.

Hi-C Contact maps

Hi-C data was aligned to the draft reference using Juicer (Durand, Shamim et al., Cell Systems, 2016), and contact maps visualizing the alignments with respect to the draft and the new reference were built using 3D-DNA (Dudchenko et al., Science, 2017). The contact maps can be explored below via Juicebox.js interactive tool (Robinson et al., Cell Systems, 2018). (Please note that the interactive figures are scaled 1:2.) To explore the assembly in greater detail, please download the .hic and .assembly files from the data release folder and use Juicebox Assembly Tools  (Dudchenko et al., bioRxiv, 2018).
