Plush-coated ringtail possum (Pseudochirops corinnae)

The plush-coated ringtail possum or golden ringtail possum is a species of marsupial from Indonesia, Papua New Guinea and the Solomon Islands. It lives in the lower montane forest. Read more about plush-coated ringtail possums on Wikipedia.

Chromosome-length genome assembly

Download the Pseudochirops_corinnae_HiC.fasta.gz file containing the chromosome-length (2n=16) assembly of the plush-coated ringtail possum genome. All modifications with respect to the draft (see below) are annotated in the Pseudochirops_corinnae_HiC.assembly file. Some basic stats associated with the new reference, Pseudochirops_corinnae_HiC, are listed below. The full data release can be explored here.

Draft

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

This genome assembly was done in collaboration with the Mallarino Lab at Princeton University. The draft genome assembly was put together from short-insert size PCR-free DNA-Seq data using w2rap-contigger (Clavijo et al. 2017).

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 kidney sample for in situ Hi-C preparation was obtained from Australian Biological Tissue Collection at the South Australian Museum.

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).
