Dingo, Desert ecotype (Canis lupus dingo, Desert ecotype)

There are at least two dingo forms, we call ecotypes, that may have colonised Australia independently or may have diverged upon arrival in Australia. These ecotypes are most commonly called Desert and Alpine types. Read more about dingo, desert ecotype on UNSW website.

Chromosome-length genome assembly

Download the sandy.combined.contigs.arrow.purged_HiC.fasta.gz file containing the chromosome-length (2n=78) assembly of the dingo, desert ecotype genome. All modifications with respect to the draft (see below) are annotated in the sandy.combined.contigs.arrow.purged_HiC.assembly file. Some basic stats associated with the new reference, sandy.combined.contigs.arrow.purged_HiC, are listed below. The full data release can be explored here.

Draft

The chromosome-length genome assembly is based on the draft assembly sandy.combined.contigs.arrow.purged, credited below.

This genome assembly was generated as part of a collaborative effort led by J. William O. Ballard, School of Biotechnology and Biomolecular Sciences, University of New South Wales, Sydney NSW 2052, Australia. The final (with additional gap-filling) version of this genome assembly is available on NCBI website as ASM325472v2.

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 blood sample for in situ Hi-C preparation was donated by a female individual named Sandy, and obtained from Vineyard Veterinary Hospital, Australia (coordinated by Robert Zammit and William Ballard).

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).
