The complete mitochondrial genome of the Vietnamese three-striped box turtle (Cuora cyclornata) was first determined in this study. It was a circular molecule of 16,594 bp in length, consisting of 37 genes typically found in other vertebrates. The AT content of the overall base composition of the whole mitogenome was 60.39%, while the control region was 70.23%. Two ETAS and 4 CSBs were identified, while a remarkable feature was found in the control region: a large number of (TTATTATA) 10 direct tandem repeats followed by (TTATA) n (n ¼ 10, 8 and 1), which were spaced into three domains by (TA) n (n ¼ 1, 1 and 2). The sequence information could play an important role in the study of phylogenetic relationships in turtles and preservation of genetic resources for helping conservation of the endangered species.

The complete mitochondrial genomes of the Spotted Anole (Anolis punctatus), Florida Scrub Lizard (Sceloporus woodi), and Mesquite Lizard (S. grammicus) were assembled and annotated. Genomic DNA of A. punctatus was sequenced in one-sixth of a lane in an Illumina HiSeq while comparable sequencing data for S. woodi and S. grammicus were retrieved from the Short Read Archive (entries SRR1286259 and SRR1145766, respectively). We assembled these mitogenomes using MIRA, NovoPlasty, and/or MITObim software. The resulting whole and circularized mitogenome assemblies exhibited typical vertebrate sequence length and gene organization. We deposited these mitogenomes into public databases under accession numbers MK091854, BK010487, and BK010486, respectively. To verify the taxonomic identifications of our mitogenomes (as iguanian lizards), we conducted maximum likelihood analyses with 14 published mitogenomes from the lizard superfamily Iguanoidea and two outgroups. Our analysis of concatenated gene sequences from mitochondria confirmed the taxonomic identities of our mitogenomes to the genus level.

A phylogenetic tree for major lineages of iguanian lizards is estimated from 1,488 aligned base positions (858 informative) of newly reported mitochondrial DNA sequences representing coding regions for eight tRNAs, ND2, and portions of ND1 and COI. Two well-supported groups are defined, the Acrodonta and the Iguanidae (sensu lato). This phylogenetic hypothesis is used to investigate evolutionary shifts in mitochondrial gene order, origin for light-strand replication, and secondary structure of tRNA Cys . These three characters shift together on the branch leading to acrodont lizards. Plate tectonics and the fossil record indicate that these characters changed in the Jurassic. We propose that changes to the secondary structure of tRNA Cys may destroy function of the origin for light-strand replication which, in turn, may facilitate shifts in gene order.

The mitogenome of the South American parthenogenetic lizard Loxopholis percarinatum Müller, 1923 (Squamata: Gymnophthalmidae), a uni-bisexual species complex, was recovered for three individuals from Rio Negro region, Amazonas, Brazil. The content and order of genes are typical for vertebrate mitochondrial genomes, and we recovered 13 protein-coding genes, 22 tRNA, and two rRNA (12S and 16S), in addition to partial fragments of the Control Region. A maximum likelihood phylogenetic analysis with mitogenomes of selected lizard families recovered L. percarinatum with Iphisa elegans Gray, 1851, the only other Gymnophthalmidae species available in GenBank.
The complete mitochondrial genome of Bothrops jararaca (Reptilia, Serpentes, Viperidae)
Mitochondrial DNA Part B, 2016
The complete mitochondrial genome, containing 17,526 bp, was determined from the pitviper Bothrops jararaca. It is the first mitogenome for the most medically important genus of snake in Latin America. This mitogenome has common snake mitochondrial features such as a duplicated control region that has nearly identical sequences at two different locations of the mitogenome and a translocation of tRNA-Leu (UUR). Besides, we found a translocation of the tRNA-Pro compared to Colubridae snakes. Finally, an unusual possible duplication containing a tRNA-Phe was observed for the first time and may represent a marker of the genus.
