Canyon mouse (Peromyscus crinitus)

Vocalizations are an important form of communication in canyon mice. When injured, adults make brief squeaking sounds, and when defending the nest, they often make "chit" sounds. When excited, canyon mice thump the ground with their hind feet, and when aggressive, they chatter their teeth! Read more about canyon mice on Animal Diversity Web.

Chromosome-length genome assembly

Download the pecr10X_v2_HiC.fasta.gz file containing the chromosome-length (2n=48) assembly of the canyon mouse genome. All modifications with respect to the draft (see below) are annotated in the pecr10X_v2_HiC.assembly file. Some basic stats associated with the new reference, pecr10X_v2_HiC, are listed below. The full data release can be explored here.

Draft

The chromosome-length genome assembly is based on the draft assembly pecr10X_v2, credited below.

The chromosome-length genome assembly was created in collaboration with the MacManes lab, University of New Hampshire. The draft genome assembly was generated using 10X data by Matthew MacManes, Anna Tigano and Jocelyn Colella, University of New Hampshire.

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 fibroblast sample for in situ Hi-C preparation was donated by a female individual, and obtained from MD Anderson Frozen Archive.

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).
