Comparative analysis of mitochondrial genomes from Buthidae (Scorpiones): gene rearrangement and phylogenetic implications
Scorpions, a diverse group of arachnids consisting of over 2,000 valid species, have received limited research attention in terms of their complete mitochondrial genomes (mitogenomes). To increase the taxonomic sampling frequency of species available for study based on mitogenomes, we reconstructed...

| description | Scorpions, a diverse group of arachnids consisting of over 2,000 valid species, have received limited research attention in terms of their complete mitochondrial genomes (mitogenomes). To increase the taxonomic sampling frequency of species available for study based on mitogenomes, we reconstructed the complete mitogenomes of five scorpions, Androctonus amoreuxi (Audouin, 1826), Hottentotta tamulus (Fabricius, 1798), Leiurus quinquestriatus (Ehrenberg, 1828), Lychas mucronatus (Fabricius, 1798), and Teruelius flavopiceus (Kraepelin, 1900) within the family Buthidae. These five mitogenomes had a typical circular structure, with total sizes ranging from 14,504 to 15,083 bp. Nucleotide composition analysis indicated that the sequences were biased toward A and T. The Ka/Ks ratios within 13 protein-coding genes (PCGs) were lower than 1, suggesting that they had been subject to purifying selection in Buthidae. Our analyses provide additional evidence on that, in scorpions, the majority of mitogenome rearrangements occurred in tRNAs. Moreover, the genes tRNA-Asp, tRNA-Gln and tRNA-Ile were the hotspots of rearrangement in this order. Phylogenetic analyses based on PCGs supported taxonomic relationships in this taxon. Our results might provide useful insights into the gene arrangement features of scorpion mitogenomes and lay the foundation for further studies on the family Buthidae. |
