The complete mitochondrial genome of the blue skate Dipturus batis

Abstract

The complete mitochondrial genome of the blue skate Dipturus batis is described from shotgun sequencing on an Illumina next-generation sequencing platform. We report a 16,911 bp long sequence similar in size to other members of the genus, containing 13 protein-coding regions, 22 tRNA genes, 2 rRNA genes, and 2 non-coding areas. Phylogenetic analysis was performed using the complete mitochondrial genomes of 17 related species, placing D. batis within the Rajini tribe of the Rajidae family, consistent with current taxonomy. The new resource adds to a growing database of rajid mitogenomes which will help resolve phylogenetic relationships within the family.

The complete mitochondrial genomes of the flapper skate Dipturus intermedius and the longnose skate Dipturus oxyrinchus

“… 2016 ; Delaval et al. 2020 ). Like other Dipturus relatives, they contain 13 protein-coding regions, 22 tRNA genes, two rRNA genes, and two non-coding areas (control region and the origin of L-strand replication).…”

“…To contribute to the knowledge of genetic differences between these commonly confused closely related species, we complement the already described mitogenome of the blue skate D. batis (Delaval et al. 2020 ) with full mitochondrial genomes of the flapper skate D. intermedius and the longnose skate D. oxyrinchus. Fin clips were collected of D. intermedius , north coast of Scotland (59° 13′ 51.6″N, 3° 29′ 49.1994″W) during a Marine Scotland Science survey under UK Home Office License, and of D. oxyrinchus , Norway (61° 29′ 17.052″N, 5° 16′ 23.7174″E) during a University of Bergen research cruise, which are now deposited in the Natural History Museum London (accession numbers NHMUK014943803 and NHMUK014943802, respectively, contact Jackie Mackenzie-Dodds j.mackenzie-dodds@nhm.ac.uk ).…”
