Mitogenome analysis of dwarf pufferfish (Carinotetraodon travancoricus) endemic to southwest India and its implications in the phylogeny of Tetraodontidae. J Genet. 2019 Dec;98: Authors: Sathyajith C, Yamanoue Y, Yokobori SI, Thampy S, Vattiringal Jayadradhan RK Abstract The Tetraodontidae (pufferfishes), is primarily a family of marine and estuarine fishes with a limited number of freshwater species. Freshwater invasions can be observed in South America, Southeast Asia and central Africa. In the present study, we have analysed the complete mitogenome of freshwater pufferfish, Carinotetraodon travancoricus (dwarf pufferfish or Malabar pufferfish) endemic to southwest India. The genome is 16487 bp in length and consist of 13 protein-coding genes, 22 transfer RNA genes, two ribosomal RNA genes and one control region like all the other vertebrate mitogenomes. The protein-coding genes ranged from 165 bp (ATP synthase subunit 8) to 1812 bp (NADH dehydrogenase subunit 5) and comprised of 11310 bp in total, constituting 68.5% of the complete mitogenome. Some overlaps have been observed in protein-coding genes by a total of 7 bp. The AT skew (0.032166) and GC skew (-0.29746) of the mitogenome indicated that heavy strand consists equal amount of A and T, but the overall base composition was mainly C skewed. The noncoding D-loop region comprised 869 bp. The conserved motifs ATGTA and its complement TACAT associated with thermostable hairpin st...
