The complete mitochondrial genome of Sarcocheilichthys variegatus wakiyae (Cypriniformes, cyprinidae) and corresponding phylogenetic analysis

Abstract

In this study, the complete mitochondrial genome of Sarcocheilichthys variegatus wakiyae was sequenced using samples collected from the Tamjin River (type locality), located in Jangheung-gun, Jeollanam-do, Republic of Korea. The complete mitochondrial genome of S. variegatus wakiyae includes 13 protein-coding genes (PCGs), 22 transfer RNA (tRNA) genes, 2 ribosomal RNA (rRNA) genes, and a control region (D-loop), with a total length of 16,675 bp. The overall base nucleotide compositions encoded are 30.15% A, 26.71% C, 16.81% G, and 26.33% T with 56.48% A + T. The phylogenetic tree constructed using a neighbor-joining (NJ) method showed that S. variegatus wakiyae and S. variegatus microoculus are not sister groups, despite being subspecies of the same taxonomic species. Rather, S. variegatus wakiyae forms a sister group with S. hainanensis.
