Orange-legged furrow bee (Halictus rubicundus)

The species exhibits different social behaviors depending on climate: it is a solitary species in high elevations or latitudes where the season is short, but eusocial in other areas. Read more about orange-legged furrow bees on iNaturalist.org.

Chromosome-length genome assembly

Download the HRUB_genome_v2.1.1.fasta.gz file containing the chromosome-length (2n=36) assembly of the orange-legged furrow bee genome. All modifications with respect to the draft (see below) are annotated in the HRUB_genome_v2.1.1.assembly file. Some basic stats associated with the new reference, HRUB_genome_v2.1.1, are listed below. The full data release can be explored here.

Draft

The chromosome-length genome assembly is based on the draft assembly HRUB_genome_v1.0, credited below.

This genome assembly was created in collaboration with the Kocher Lab at Princeton University. The draft was assembled with Supernova assembler using 10x Genomics linked-read libraries. For details see https://www.biorxiv.org/content/10.1101/2021.04.14.439731v1..

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 head and thorax sample for in situ Hi-C preparation was donated by a female individual named COI-eq ID: N/A, Legacy ID: HRUB046, 4-letter alias: HRUB, alt: Apo0051, and obtained from Karen M. Kapheim (Utah State University).

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).
