Large flying fox (Pteropus vampyrus)

Despite the 'vampire' in their scientific name, large flying foxes feed exclusively on fruits, nectar and flowers! Read more about large flying foxes in Wildscreen Arkive.

Chromosome-length genome assembly

Download the Pvam_2.0_HiC.fasta.gz file containing the chromosome-length (2n=38) assembly of the large flying fox genome. All modifications with respect to the draft (see below) are annotated in the Pvam_2.0_HiC.assembly file. Some basic stats associated with the new reference, Pvam_2.0_HiC, are listed below. The full data release can be explored here.

Draft

The chromosome-length genome assembly is based on the draft assembly Pvam_2.0 (GCA_000151845.2), credited below.

These are improved versions of the contigs from Lindblad-Toh, Kerstin, Manuel Garber, Or Zuk, Michael F. Lin, Brian J. Parker, Stefan Washietl, Pouya Kheradpour, et al. 2011.

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, and provided to us by SeaWorld.

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).
