Complete mitochondrial genome of Pterophyllum scalare (Perciformes, Cichlidae)

Abstract

The complete mitochondrial genome of Pterophyllum scalare was determined in order to characterize and compare their mitochondrial genomes (GenBank accession number KP231206). The total length of the mitochondrial genome was 16,581 bp which contained 37 genes (13 protein-coding genes, two ribosomal RNA, and 22 transfer RNAs) and a major non-coding control region which was similar to those reported mitochondrial genomes. Phylogenetic analyses identified P. scalare shared 80–86% sequence identity with other assayed fishes. The relationship was more close to the cichlid family in the perciformes. Most genes were encoded on the H-strand, except for the ND6 and eight tRNA genes, encoding on the L-strand. The nucleotide skewness for the coding strands of P. scalare (AT-skew = 0.02, GC-skew = −0.32) was biased toward A and C. The complete mitogenome may add new information to existing mitogenome data for cichlids, providing further information that may contribute for their taxonomy, evolution, and phylogeny.
