Complete mitochondrial genome ofTeratoscincus przewalskii(Reptilia, Squamata, Sphaerodactylidae) and phylogenetic analysis

Abstract

The complete mitochondrial genome of the lizard, Teratoscincus przewalskii, which belongs to the family Sphaerodactylidae was determined based on Illumina data in this study. The result showed that the closed double-stranded circular mitogenome was 16,779 bp in total length (GenBank accession number: MW491837) with 44.07% GC. The complete mitochondrial genome consisted of 13 protein-coding genes, 22 transfer RNA genes, two ribosomal genes, and one noncoding control region. Phylogenetic analysis using mitochondrial genomes suggested that T. przewalskii was most closely related to its congener T. keyserlingii. This work provides valuable molecular information for further research on species identification and molecular evolution.

A complete mitogenome of the Przewalski’s Wonder Gecko (Teratoscincus przewalskii) from the Junggar Basin in Northwest China with its phylogenetic implications

“…The uncorrected p-distance between our sample and that of Yu et al. ( 2021 ), was 0.15%, calculated in MEGA 7 (Kumar et al. 2016 ).…”

“…Strikingly, in Yu et al. ( 2021 ), T. przewalskii was inferred to be more closely related to T. keyserlingii than to T. roborowskii . This unexpected phylogenetic position of T. przewalskii was inconsistent with all previous findings (Macey et al.…”

“… 2020 ; Yu et al. 2021 ). Except for ND6 and eight tRNA genes ( tRNA-Gln , Ala , Asn , Cys , Tyr , Ser [ UCA ] , Glu , and Pro ), the remaining genes were encoded on heavy strand (H-strand).…”

“…A complete mitochondrial genome of T. przewalskii was determined by using using Illumina Novaseq platform (Yu et al. 2021 ), which was collected from Ejin Banner, Alxa League, Inner Mongolia, China. Strikingly, in Yu et al.…”

“…To test the phylogenetic hypothesis of Yu et al. ( 2021 ), in this study, we report a whole mitochondrial DNA genome of T. przewalskii by Sanger sequencing, which was collected from the Junggar Basin (45.078°N, 85.391°E), Xinjiang Uygur Autonomous Region, China, in July 2017. A piece of muscle was dissected from the gecko, which had been euthanized with an overdose of sodium pentobarbital delivered by intraperitoneal injection.…”
