Chromosome-level genome assembly of the copepod Eurytemora carolleeae (Atlantic clade of the Eurytemora affinis species complex)

A. Circos plot showing the genomic landscape, including: (I) four chromosomes on the Mb scale; (II) density of protein-coding genes; (III) distribution of GC content (mean GC = 33.0%); and (IV) distribution of repetitive sequences. All distributions were calculated with 100-kb non-overlapping sliding windows, except for the distribution of GC content, which was calculated with 10-kb sliding windows. B. Circular diagram showing proportion of different categories of repetitive sequences identified in the copepod genome, with the numbers on the diagram indicating their percentage of occupied length in the genome assembly. Repetitive sequences comprise 46.1% of this copepod genome. C. Well-isolated cell showing the karyotype of E. carolleeae (2n = 8) at metaphase. D. Hi-C contact map of the genome generated by Juicebox. Chr, chromosome; LINE, long interspersed nuclear element; LTR, long terminal repeat; Hi-C, high-throughput chromosome conformation capture.
