Golden perch (Macquaria ambigua)

Golden perch or "yellowbelly" are one of the main large-bodied native fish of that support the freshwater recreational fishing industry. Golden perch are also of high cultural importance for many First Nations. Read more about golden perch on the Australian Government Department of Agriculture, Water and Environment website.

Chromosome-length genome assembly

Download the GOP001_1.1_HiC.fasta.gz file containing the chromosome-length (2n=48) assembly of the golden perch genome. All modifications with respect to the draft (see below) are annotated in the GOP001_1.1_HiC.assembly file. Some basic stats associated with the new reference, GOP001_1.1_HiC, are listed below.

Draft

The chromosome-length genome assembly is based on the draft assembly GOP001_1.1 (GCA_008360985.1), credited below.

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 fin clip sample for in situ Hi-C preparation was donated by a female individual, and obtained from James O'Dwyer (LaTrobe University Melbourne).

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). 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).
