Characterization of the complete mitochondrial genome of smallscale blackfish Girella melanichthys (Perciformes: Kyphosidae)

Abstract

The complete mitochondrial genome of smallscale blackfish, Girella melanichthys (Perciformes: Kyphosidae), was analyzed using MGISEQ-2000 platform. The assembled mitogenome had 16,518 nucleotides (overall A + T contents 56.2%), containing canonical 13 protein-coding genes (PCGs), 22 transfer RNA genes, 2 ribosomal RNA genes, and 1 putative control region. Among 13 PCGs, seven genes (ND2, ND3, ND4, COII, COIII, CytB, ATPase6) had incomplete stop codons. The phylogenetic study revealed that G. melanichthys is more closely related to G. leonina than G. punctate. This study will be useful to shed light on the evolution of the family Kyphosidae and the genus Girella.
