Chromosomal-level assembly of Tokudaia osimensis, Tokudaia tokunoshimensis, and Tokudaia muenninki genomes.

ABSTRACT: Herein, we present the first high-quality long-read-based chromosome-level genome assemblies and gene annotations of the genomes of three endangered Tokudaia species: Tokudaia osimensis, Tokudaia tokunoshimensis, and Tokudaia muenninki. These species, which are endemic to different islands of the Ryukyu Islands, Japan, exhibited unique karyotypes and sex chromosomal characteristics. The genome assemblies generated using PacBio, Illumina, and Hi-C sequence data consisted of 13 (corresponded to 12 autosomes and one X chromosome), 23 (corresponded to 22 autosomes and one X chromosome), and 23 (corresponded to 21 autosomes and the neo- and ancestral X regions) chromosome-level scaffolds that contained 2,445, 2,477, and 2,661 Mbp of sequence data, respectively.
