Red panda (Ailurus fulgens)

The sound red pandas make is known as twittering! Read more about red pandas in Scientific American and in our Chromognomes Comic Series.

Chromosome-length genome assembly

Download the ASM200746v1_HiC.fasta.gz file containing the chromosome-length (2n=36) assembly of the red panda genome. All modifications with respect to the draft (see below) are annotated in the ASM200746v1_HiC.assembly file. Some basic stats associated with the new reference, ASM200746v1_HiC, are listed below. The full data release can be explored here.

Draft

The chromosome-length genome assembly is based on the draft assembly ASM200746v1 (GCA_002007465.1), credited below.

Yibo Hu, Qi Wu, Shuai Ma, Tianxiao Ma, Lei Shan, Xiao Wang, Yonggang Nie, et al. 2017. "Comparative Genomics Reveals Convergent Evolution between the Bamboo-Eating Giant and Red Pandas." Proceedings of the National Academy of Sciences of the United States of America 114 (5): 1081-86. https://doi.org/10.1073/pnas.1613870114.

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 Take`, and provided to us by 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). (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).
