Abstract:
The complete mitochondrial genomes of two ornamental fishes, black molly (Poecilia sphenops) and blue gourami (Trichogaster trichopterus), were obtained by the traditional polymerase chain reaction (PCR)-based sequencing approach. The mitogenomes of P. sphenops and T. trichopterus are determined as 16,533 bp and 16,456 bp in length, respectively. Both the genomes include 22 transfer RNA genes, 13 protein-coding genes and 2 ribosomal RNA genes. Phylogenetic tree was constructed based on the complete mitogenomes of these two species and closely related 20 teleost species to assess their phylogenic relationship and evolution.
