The genome sequence of the Brown Litter Worm, Bimastos eiseni (Levinsen, 1884)

Keiron D Brown et al. Wellcome Open Res. .

Abstract

We present a genome assembly from an individual Bimastos eiseni (the Brown Litter Worm; Annelida; None; Haplotaxida; Lumbricidae). The genome sequence is 660.5 megabases in span. Most of the assembly is scaffolded into 17 chromosomal pseudomolecules. The mitochondrial genome has also been assembled and is 15.34 kilobases in length.

Keywords: Bimastos eiseni; Brown Litter Worm; Haplotaxida; chromosomal; genome sequence.

The BlobToolKit Snailplot shows N50 metrics and BUSCO gene completeness. The main plot is divided into 1,000 size-ordered bins around the circumference with each bin representing 0.1% of the 660,529,080 bp assembly. The distribution of scaffold lengths is shown in dark grey with the plot radius scaled to the longest scaffold present in the assembly (71,778,175 bp, shown in red). Orange and pale-orange arcs show the N50 and N90 scaffold lengths (41,312,700 and 23,769,983 bp), respectively. The pale grey spiral shows the cumulative scaffold count on a log scale with white scale lines showing successive orders of magnitude. The blue and pale-blue area around the outside of the plot shows the distribution of GC, AT and N percentages in the same bins as the inner plot. A summary of complete, fragmented, duplicated and missing BUSCO genes in the metazoa_odb10 set is shown in the top right. An interactive version of this figure is available at https://blobtoolkit.genomehubs.org/view/whEisEise2_1/dataset/whEisEise2_1/snail.

Scaffolds are coloured by phylum. Circles are sized in proportion to scaffold length. Histograms show the distribution of scaffold length sum along each axis. An interactive version of this figure is available at https://blobtoolkit.genomehubs.org/view/whEisEise2_1/dataset/whEisEise2_1/blob.

Figure 4.. Genome assembly of Bimastos eiseni, whEisEise2.1: BlobToolKit cumulative sequence plot.
The grey line shows cumulative length for all scaffolds. Coloured lines show cumulative lengths of scaffolds assigned to each phylum using the buscogenes taxrule. An interactive version of this figure is available at https://blobtoolkit.genomehubs.org/view/whEisEise2_1/dataset/whEisEise2_1/cumulative.
