Peponocephala_electra genome assembly

Here, we assembled a high-quality, chromosome-level genome of P. electra based on PacBio long reads and Hi-C sequencing data. The final assembled genome size was 2.29 Gb with a contig N50 of 82.36 Mb and a scaffold N50 of 102.72 Mb. And, 2.22 Gb (96.93%) of the genome was anchored into the 22 chromosomes. The final genome assembly showed high completeness with a BUSCO score of 96.6%. A total of 21,492 protein-coding genes were predicted in the genome assembly. The average lengths of coding sequences (CDSs), exons, and introns were 1,432 bp, 179 bp, and 3,405 bp, respectively. Finally, 1,011.15 Mb (43.12%) of the genome consisted of repeat sequences with the greatest proportion of LINEs (14.25%). Thus, the melon-headed whale genome is an important resource for future studies of cetacean biology, evolution, and conservation.
