Mongoose lemur (Eulemur mongoz)

More than other lemurs, mongoose lemurs might be active at different times of the day depending on the time of year. During wet season, they are active during the day, and on the onset of the dry season they shift towards nocturnal behavior! Read more about mongoose lemurs on Duke Lemur Center website.

Chromosome-length genome assembly

Download the Eulemur_mongoz_HiC.fasta.gz file containing the chromosome-length (2n=60) assembly of the mongoose lemur genome. All modifications with respect to the draft (see below) are annotated in the Eulemur_mongoz_HiC.assembly file. Some basic stats associated with the new reference, Eulemur_mongoz_HiC, are listed below. The full data release can be explored here.

The chromosome-length genome assembly is based on the draft assembly Eulemur_mongoz, credited below.

The draft assembly was generated by the DNA Zoo team from short insert-size PCR-free DNA-Seq data using w2rap-contigger (Clavijo et al. 2017), see (Dudchenko et al., 2018) for details.


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).
