Mitochondrial DNA B Resour. 2021 Feb 15;6(2):540-541. doi: 10.1080/23802359.2020.1756482.

Abstract

We describe the complete mitochondrial genome of the endangered fish Sinocyclocheilus aluensis. It is a circular molecule of 16,583 bp in size with a D-loop region and contains 22 transfer RNA (tRNA) genes, 2 ribosomal RNA (rRNA) genes and 13 protein-coding genes, and all genes show the typical gene arrangement conforming to the vertebrate consensus. The overall base composition of S. aluensis mitogenome is 31.1% for A, 26.9% for C, 16.6% for G, and 25.4% for T. The percentage of G + C content is 43.5%. Phylogenetic analysis demonstrated that all Sinocyclocheilus species clustered together and formed a monophyletic group. The mitochondrial genome sequencing for S. aluensis in this study provides important molecular data for further evolutionary research for Sinocyclocheilus.
