The complete mitochondrial genome of Sardinops sagax (Jenyns, 1842) (Clupeiformes: Clupeidae) and phylogenetic analyses of sardines.

ABSTRACT: Pacific sardine Sardinops sagax (Jenyns, 1842), a sardine species that widely distributes in Pacific, is an important commercial species in many areas. In this study, we characterized the complete mitochondrial genome of S. sagax using next generation sequencing technology. The complete mitogenome of S. sagax was 16,883 base pairs (bp) in length and comprised 13 protein-coding genes (PCGs), 22 transfer RNA (tRNA) genes, 2 ribosomal RNA genes (rRNA), and one control region (D-loop). Phylogenetic analysis indicated that sardine species included three clades (I, II and III) and S. sagax clustered with Sardinops melanostictus.

The complete mitochondrial genome of Sardinella zunasi (Clupeiformes: Clupeidae).

Project description:The complete mitogenome of Sardinella zunasi was determined by next-generation sequencing. The S. zunasi mitogenome was a circular 16,307 bp molecule that contained 13 protein-coding genes, 22 tRNA genes, 2 rRNA genes, and one control region (D-loop). The gene arrangement was consistent with other Sardinella mitogenomes. The phylogenetic relationships of 29 Clupeoidei species based on 13 protein-coding genes from the available mitogenomes were analyzed. Sardinella zunasi clustered with Sardinella among Clupeidae, suggesting a closer relationship with this genus. These results will be useful for understanding the phylogenetic relationships, taxonomic classification, and phylogeography of the genus Sardinella relative to other genera of Clupeoidei.

Phylogenetic relationships, origin and historical biogeography of the genus Sprattus (Clupeiformes: Clupeidae).

Project description:The genus Sprattus comprises five species of marine pelagic fishes distributed worldwide in antitropical, temperate waters. Their distribution suggests an ancient origin during a cold period of the earth's history. In this study, we evaluated this hypothesis and corroborated the non-monophyly of the genus Sprattus, using a phylogenetic approach based on DNA sequences of five mitochondrial genome regions. Sprattus sprattus is more closely related to members of the genus Clupea than to other Sprattus species. We also investigated the historical biogeography of the genus, with the phylogenetic tree showing two well-supported clades corresponding to the species distribution in each hemisphere. Time-calibrated phylogenetic analyses showed that an ancient divergence between Northern and Southern Hemispheres occurred at 55.8 MYBP, followed by a diversification in the Oligocene epoch in the Northern Hemisphere clade (33.8 MYBP) and a more recent diversification in the Southern Hemisphere clade (34.2 MYBP). Historical biogeography analyses indicated that the most recent common ancestor (MRCA) likely inhabited the Atlantic Ocean in the Southern Hemisphere. These results suggest that the ancestral population of the MRCA diverged in two populations, one was dispersed to the Northern Hemisphere and the other across the Southern Hemisphere. Given that the Eocene was the warmest epoch since the Paleogene, the ancestral populations would have crossed the tropics through deeper cooler waters, as proposed by the isothermal submergence hypothesis. The non-monophyly confirmed for the genus Sprattus indicates that its systematics should be re-evaluated.

Project description:In this study, the complete mitochondrial genome of Engraulis ringens has been determined. The whole sequence is 16,690?bp in length and included the typical structure of 13 protein-coding genes, 22 tRNA genes, 2 rRNA genes, and 2 non-coding regions (control region and L-strand replication origin). The overall base composition includes A 26.65%, T 26.09%, C 28.13%, G 19.13%, with a slightly A?+?T bias of 52.74%. Moreover, the 13 PCGs encode 3797 amino acids in total. The phylogenetic analysis of E. ringens in the Engraulidae family was constructed based on 12 PCGs encoded by the heavy strand, and the result showed that E. ringens is most closely related to Engraulis japonicus and Engraulis encrasicolus.

The complete mitochondrial genome of Thryssa hamiltonii and phylogenetic analysis of Engraulidae (Clupeiformes; Clupeoidei).

Project description:This study aimed to elucidate the complete mitochondrial genome (mitogenome) of Thryssa hamiltonii (Clupeiformes: Engraulidae). The circular mitogenome is 16,737-bp-long, including 13 protein-coding genes, 22 tRNA genes, two rRNA genes, and a non-coding control region as observed in other vertebrates.

Phylogenetic analysis of 16 species in family Engraulidae revealed that T. hamiltonii clustered in subfamily Engraulinae and is closely related to Lycothrissa crocodilus. The present data will contribute to future phylogenetic studies on members of family Engraulidae and conservation strategies for T. hamiltonii.

The complete mitochondrial genome of Thryssa kammalensis (Clupeiformes: Engraulidae).

Project description:In this study, the complete mitochondrial genome (mitogenome) sequence of Thryssa kammalensis has been determined by long polymerase chain reaction and primer walking methods. The mitogenome is a circular molecule of 16 968 bp in length and contains 37 mitochondrial genes including 13 protein-coding genes, two ribosomal RNA (rRNA), 22 transfer RNA (tRNA) and a control region as other bony fishes. Within the control region, we identified the termination-associated sequence (TAS) domain, the central conserved sequence block domains (CSB-F, CSB-E and CSB-D) and the conserved sequence block domains (CSB-1, CSB-2 and CSB-3). There are eight copies of tandem repeats of 38 bp in the control region, which contain TAS.

Phylogenetic analyses of complete mitochondrial genome sequences suggest a basal divergence of the enigmatic rodent Anomalurus.

Project description:BACKGROUND: Phylogenetic relationships between Lagomorpha, Rodentia and Primates and their allies (Euarchontoglires) have long been debated. While it is now generally agreed that Rodentia constitutes a monophyletic sister-group of Lagomorpha and that this clade (Glires) is sister to Primates and Dermoptera, higher-level relationships within Rodentia remain contentious. RESULTS: We have sequenced and performed extensive evolutionary analyses on the mitochondrial genome of the scaly-tailed flying squirrel Anomalurus sp., an enigmatic rodent whose phylogenetic affinities have been obscure and extensively debated. Our phylogenetic analyses of the coding regions of available complete mitochondrial genome sequences from Euarchontoglires suggest that Anomalurus is a sister taxon to the Hystricognathi, and that this clade represents the most basal divergence among sampled Rodentia. Bayesian dating methods incorporating a relaxed molecular clock provide divergence-time estimates which are consistently in agreement with the fossil record and which indicate a rapid radiation within Glires around 60 million years ago. CONCLUSION: Taken together, the data presented provide a working hypothesis as to the phylogenetic placement of Anomalurus, underline the utility of mitochondrial sequences in the resolution of even relatively deep divergences and go some way to explaining the difficulty of conclusively resolving higher-level relationships within Glires with available data and methodologies.
