Complete mitochondrail genome of Corydoras panda (Teleostei, Siluriformes, Callichthyidae, Corydoradinae)

Abstract

We reported the complete mitochondrial genome yielded by next-generation sequencing of Corydoras panda in this study. The total length of the mitochondrial genome is 16,611 bp, with the base composition of 32.50% A, 26.30% T, 26.10% C, and 15.10% G, respectively. 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. The complete mitogenomes of C. panda and other 18 species from Siluriformes were used for phylogenetic analysis using Neighbor-Joining method. The topology demonstrated that all species belong to nine genera are divided into three groups (Siluridae, Loricariidae, and Callichthyidae), and the C. panda was clustered with other species from genus Corydoras. Corydoras panda external morphological feature classification is consistent with the molecular classification results, so the information of the mitogenome could be used for future identification of Corydoras species.
