The genome sequence of the butterfly blenny, Blennius ocellaris Linnaeus, 1758

Patrick Adkins et al. Wellcome Open Res. .

Abstract

We present a genome assembly from a specimen of Blennius ocellaris (the butterfly blenny; Chordata; Actinopteri; Blenniiformes; Blenniidae). The genome sequence spans 728.70 megabases. Most of the assembly is scaffolded into 24 chromosomal pseudomolecules. The mitochondrial genome has also been assembled and is 16.5 kilobases in length.

Keywords: Blenniiformes; Blennius ocellaris; butterfly blenny; chromosomal; genome sequence.

Figure 2.. Genome assembly of Blennius ocellaris, fBleOce1.1: metrics.
The BlobToolKit snail plot 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 728,745,255 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 (37,598,765 bp, shown in red). Orange and pale-orange arcs show the N50 and N90 scaffold lengths (29,635,927 and 19,804,534 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 actinopterygii_odb10 set is shown in the top right.

Sequences are coloured by phylum. Circles are sized in proportion to sequence length. Histograms show the distribution of sequence length sum along each axis. An interactive version of this figure is available at https://blobtoolkit.genomehubs.org/view/CAUJSF01/dataset/CAUJSF01/blob.

Figure 4.. Genome assembly of Blennius ocellaris fBleOce1.1: BlobToolKit cumulative sequence plot.
The grey line shows cumulative length for all sequences. Coloured lines show cumulative lengths of sequences assigned to each phylum using the buscogenes taxrule. An interactive version of this figure is available at https://blobtoolkit.genomehubs.org/view/CAUJSF01/dataset/CAUJSF01/cumulative.
