Next-generation sequencing yields the complete mitochondrial genome of Corydoras sterbai (Teleostei, Siluriformes, Callichthyidae, Corydoradinae)

Abstract

In this work, we reported the complete mitochondrial genome yielded from next-generation sequencing of Corydoras sterbai. The total length of the mitochondrial genome is 16,636 bp, with the base composition of 32.70% A, 26.40% T, 26.00% C, and 14.90% G. It contains two ribosomal RNA genes, 13 protein-coding genes, 22 transfer RNA genes, and a major non-coding control region (D-loop region). The arrangement of these genes is the same as that found in the Siluriformes. All the protein initiation codons are ATG, except for cox1 that begins with GTG. The Neighbour-Joining tree built using Geneious showed that C. sterbai was clustered with other species from the genus Corydoras. It means that its external morphological feature classification is consistent with the molecular classification results.
