Chromosome-length genome assembly

Download the cmucedo.flye2_HiC.fasta.gz file containing the chromosome-length (2n=16) assembly of the moss animal genome. All modifications with respect to the draft (see below) are annotated in the cmucedo.flye2_HiC.assembly file. Some basic stats associated with the new reference, cmucedo.flye2_HiC, are listed below.

Draft

The chromosome-length genome assembly is based on the draft assembly cmucedo.flye2, credited below.

This assembly has been generated in collaboration with Leonid Moroz and Andrea Kohn, University of Florida. The draft was generated by the DNA Zoo team from PacBio data produced at UofF using Flye (Kolmogorov et al., 2019).

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 30 whole animals sample for in situ Hi-C preparation was obtained from Leonid Moroz, University of Florida. We thank Moroz for additional samples for this species.

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).
