Bryde's whale (Balaenoptera edeni)

Bryde's whales have a wide distribution and occur in tropical, subtropical, and warm temperate waters around the world. They live in all oceans! Read more about Bryde's whales on NOAA Fisheries website.

Chromosome-length genome assembly

Download the Balaenoptera_edeni_HiC.fasta.gz file containing the chromosome-length (2n=44) assembly of the Bryde's whale genome. All modifications with respect to the draft (see below) are annotated in the Balaenoptera_edeni_HiC.assembly file. Some basic stats associated with the new reference, Balaenoptera_edeni_HiC, are listed below. The full data release can be explored here.

Draft

The chromosome-length genome assembly is based on the draft assembly Balaenoptera_edeni, 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. This work was performed under Marine Mammal Health and Stranding Response Program (MMHSRP) Permit No. 18786-03 issued by the National Marine Fisheries Service (NMFS) under the authority of the Marine Mammal Protection Act (MMPA) and Endangered Species Act (ESA). The specimen(s) used in this study were collected by the NMFS Panama City Lab/Lydia Staggs and provided by the National Marine Mammal Tissue Bank, which is maintained in the Marine Environmental Specimen Bank (Marine ESB) at NIST, and which is operated under the direction of NMFS with the collaboration of USGS, USFWS, MMS, and NIST through the Marine Mammal Health and Stranding Response Program.

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 kidney sample for in situ Hi-C preparation was donated by a female individual, and obtained from National Marine Mammal Tissue Bank maintained by the National Institute of Standards and Technology (NIST) in the NIST Biorepository.

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).
