Next-generation sequencing yields a nearly complete mitochondrial genome of the Multiocellated Racerunner (Eremias multiocellata) in Northwest China

Abstract

The viviparous Multiocellated Racerunner, Eremias multiocellata, is widespread in North China, Mongolia, and the Tuva Republic of Russia. A nearly complete mitochondrial genome of one individual from the suburb of Jingyuan County in Northwest China was determined by next-generation sequencing. The mitogenome is 17,333 bp in size, comprising 2 ribosomal RNA genes, 13 protein-coding genes (PCGs), 22 transfer RNA genes (tRNAs), and one control region. The gene arrangement and composition is similar to the typical mitochondrial DNA of vertebrates. With exception to the control region, all of the 37 genes were completely recovered. The concatenated PCGs were used to conduct Bayesian phylogenetic analyses together with several related lizards with mitogenome data in GenBank. The resulting phylogenetic tree confirmed the monophyly of both genus Eremias and its viviparous group. The mitogenome sequence will provide fundamental data for resolving phylogenetic and genetic problems related to Eremias viviparity.
