Abstract

We present the complete mitochondrial genome sequence of the Variable Platyfish, Xiphophorus variatus (Meek 1904) (Cyprinodontiformes: Poeciliidae). The genome consists of 16,624 bp which encodes 13 protein-coding genes, 22 transfer RNAs, 2 ribosomal RNAs, and 1 control region. Genome-wide nucleotide composition is 27.79% adenine, 31.11% cytosine, 15.63% guanine, and 25.48% thymine. The X. variatus mitochondrial genome shares similar GC content and identical gene order and gene strand location with other members of Poeciliidae. The sequence presented herein will be of utility for future phylogenetic and biomedical research and for designing primers for species detection from environmental DNA samples.

Keywords: Oxford Nanopore; Xiphophorus variatus; invasive species; mitochondrial genome.

The evolutionary history of Poeciliidae mitogenomes was inferred by using the maximum-likelihood method in the RAxML-HPC BlackBox through the CIPRES portal using 16,944 bp. The resulting file was viewed in Dendroscope. Numbers on branch lengths are bootstrap support values in %. The study species, Xiphophorus variatus, is boldened.
