Abstract:
Here we report, for the first time, the complete mitochondrial genome of Astyanax giton which, together with other species, are popularly known as tetras. The mitogenome's length is 16,643 bp, containing 13 protein-encoding genes (CDS), two ribosomal RNAs (rRNA), 22 RNA transfer (tRNA) and one control region (D-loop). As for other vertebrates, all genes are encoded on the heavy strand except for ND6 and eight tRNA genes. In the phylogenetic analyses, this species and other Astyanax were paraphyletic.
