Project description:The Korean oily shinner (Sarcocheilichthys nigripinnis morii) is a subspecies belonging to the subfamily Gobioninae in the family Cyprinidae and is endemic to Korea. Herein, we report the first sequencing and assembly of the complete mitochondrial genome of S. nigripinnis morii. The complete mitochondrial genome is 16,679 bp long, consisting of 13 protein-coding genes, 22 tRNA genes, 2 rRNA genes, and a control region. It has the typical vertebrate mitochondrial gene arrangement. Phylogenetic analysis using mitogenomes of 16 species showed that S. nigripinnis morii was clustered with S. nigripinnis and S. variegatus microoculus and grouped with the other Cyprinidae species.
