Data from: The first complete mitochondrial genome of the Indian Tent Turtle, Pangshura tentoria (Testudines: Geoemydidae): characterization and comparative analysis
Characterization of complete mitogenome is a widely used genomics study for species delineation and evolutionary research. However, the sequences and structural motifs contained within the mitogenome have been rarely examined to understand the phylogeny and evolutionary history among Testudines. Hence, the mitogenomic features of several Testudines taxa are still anonymous to the scientific communities. The present study decodes the first complete mitochondrial genome of the Indian Tent Turtle, Pangshura tentoria (16,657 bp) by using next-generation sequencing. This denovo assembly encodes 37 genes: 13 protein coding genes (PCGs), 22 transfer RNA (tRNAs), two ribosomal RNA (rRNAs), and one control region (CR). The mitogenome contained 19 intergenic spacer and six overlapping regions. Most of the genes were encoded on majority strand, except for one PCG (NADH dehydrogenase subunit 6) and eight tRNAs. Most of the PCGs were started with an ATG initiation codon, except for cytochrome oxidase subunit 1 with 'GTG' and NADH dehydrogenase subunit 5 with 'ATA'. The termination codons, 'TAA' and 'AGA' were observed in NADH dehydrogenase subunit 4l and NADH dehydrogenase subunit 6 respectively. The Relative Synonymous Codon Usage analysis revealed the maximum abundance of Alanine, Isoleucine, Leucine, and Threonine. The non-synonymous/synonymous ratios were <1 in all PCGs, which indicates strong negative selection among all Geoemydid species. The study also found the typical cloverleaf secondary structure in most of the tRNA genes, except for Serine (trnS1) with lack of the conventional DHU arm. The Wobble base pairing was observed in the different stems (DHU, acceptor, and anticodon) of 11 tRNAs. The comparative study of Geoemydid mitogenomes revealed the occurrence of tandem repeats was frequent in the 3´ end of CR. Further, two copies of a unique tandem repeat 'TTCTCTTT' were identified in P. tentoria. The Bayesian and Maximum Likelihood phylogenetic trees using concatenation of 13 PCGs revealed the close relationships of P. tentoria with Batagur trivittata in the studied dataset. All the Geoemydid species showed distinct clustering with high bootstrap support congruent with previous evolutionary hypotheses. We suggest that the generations of more mitogenomes of Geoemydid species, especially for Batagurinae subfamily, are required to improve our understanding their in-depth phylogenetic and evolutionary relationships.
Data from: Complex phylogeography in Rhinoclemmys melanosterna: conflicting mitochondrial and nuclear evidence suggests past hybridization (Testudines: Geoemydidae)
We examined differentiation within the Colombian wood turtle Rhinoclemmys melanosterna, and among R. melanosterna and the closely allied species R. diademata, R. funerea and R. punctularia, based on 1060 base pairs of the mitochondrial cyt b gene. We also assessed the phylogenetic relationships among these species using 2050 bp of mtDNA (partial cyt b, 12S and 16S genes) and 3620 bp of nuclear DNA (partial Rag 1, Rag 2, C-mos, R35 and ODC genes). There is considerable phylogeographic structuring within R. melanosterna, with seven distinct clades distributed across the species' range. These clades correspond to some extent with previously described differences in the dorsal pattern of head coloration. Individual and combined analyses of mitochondrial and nuclear DNA indicated contradictory relationships among R. melanosterna, R. diademata, R. funerea and R. punctularia. Mitochondrial DNA sequences revealed R. melanosterna to be non-monophyletic with respect to R. diademata, R. funerea and R. punctularia. In contrast, R. melanosterna constituted a well-supported monophyletic clade using nuclear DNA. This conflict between mitochondrial and nuclear data suggests past gene flow among the allopatrically and parapatrically distributed species R. melanosterna, R. diademata, R. funerea and R. punctularia. Compared to the other Rhinoclemmys species, the taxa under study are weakly differentiated. To assess their taxonomic status, further research is warranted using additional nuclear markers and additional samples of R. diademata, R. funerea and R. punctularia. For the time being, a continued classification of R. melanosterna, R. diademata, R. funerea and R. punctularia as distinct species is justified owing to their allopatric and parapatric distributions, and to conserve the established usage of names that is based on characteristic and distinct phenotypes associated with each species.
