Central bearded dragon (Pogona vitticeps)

When threatened, central bearded dragons inflate and puff up their throats. These enlarged throat pouches resemble human beards, hence their name! Read more about central bearded dragons on Animalia website.

Chromosome-length genome assembly

Download the pvi1.1_HiC.fasta.gz file containing the chromosome-length (2n=32) assembly of the central bearded dragon genome. All modifications with respect to the draft (see below) are annotated in the pvi1.1_HiC.assembly file. Some basic stats associated with the new reference, pvi1.1_HiC, are listed below.

Draft

The chromosome-length genome assembly is based on the draft assembly pvi1.1 (GCF_900067755.1), credited below.

Georges, A., Li, Q., Lian, J., O'Meally, D., Deakin, J., Wang, Z., Zhang, P., Fujita, M., Patel, H.R., Holleley, C.E., Zhou, Y., Zhang, X., Matsubara, K., Waters, P., Graves, J.A., Sarre, S.D., Zhang, G. 2015. High-coverage sequencing and annotated assembly of the genome of the Australian dragon lizard Pogona vitticeps. Gigascience 4, 45. https://doi.org/10.1186/s13742-015-0085-2.

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 male individual named Norman, and obtained from Houston Zoo.

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).
