Viereck's sweat bee (Lasioglossum vierecki)

Since L. vierecki and other native bees have become more important for agriculture due to the decline in population of honey bees, there are new efforts to sustain and promote these species. Some farmers are now raising native plants that these bees feed from in order to ensure that their farming practices do not negatively affect the native bee population.

Chromosome-length genome assembly

Download the LVIE_genome_v2.1.1.fasta.gz file containing the chromosome-length (2n=22) assembly of the viereck's sweat bee genome. All modifications with respect to the draft (see below) are annotated in the LVIE_genome_v2.1.1.assembly file. Some basic stats associated with the new reference, LVIE_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 LVIE_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: LVIE030, 4-letter alias: LVIE, alt: Apo0035, and obtained from Kocher Lab, Princeton 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).
