The genome sequence of a hydroid, Candelabrum cocksii (Cocks, 1854)

Patrick Adkins et al. Wellcome Open Res. .

Abstract

We present a genome assembly from an individual Candelabrum cocksii (hydroid; Cnidaria; Hydrozoa; Anthoathecata; Candelabridae). The genome sequence is 232.9 megabases in span. Most of the assembly is scaffolded into 15 chromosomal pseudomolecules. The mitochondrial genome has also been assembled and is 14.55 kilobases in length.

Keywords: Anthoathecata; Candelabrum cocksii; a hydroid; chromosomal; genome sequence.

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 232,868,000 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 (21,456,843 bp, shown in red). Orange and pale-orange arcs show the N50 and N90 scaffold lengths (16,016,071 and 12,720,173 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.

Sequences are coloured by phylum. Circles are sized in proportion to sequence length. Histograms show the distribution of sequence length sum along each axis.
