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

ABSTRACT: 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.

Characterization of the complete mitochondrial genome sequence of Coilia brachygnathus (Clupeiformes, Engraulidae) from Huai River and its phylogenetic position.

Project description:The complete mitogenome sequence of Coilia brachygnathus (Kreyenberg & Pappenheim, 1908) from Wabu Lake in Huai River Basin was annotated and characterized in this study. This mitochondrial genome is a circular DNA molecule of 16.896 bp in size with 57.52% AT content, including 13 protein-coding genes (PCGs), two ribosomal RNA genes (rRNAs), 22 transfer RNA genes (tRNAs), and an AT-rich region (control region) as other bony fishes. There are a total of 10 overlap locations and 15 intergenic spacer regions throughout the mitogenome of C. brachygnathus. All PCGs employed a standard ATG as a start codon, except cytochrome c oxidase 1 (cox1) with GTG. In addition, TAA or TAG was identified as the typical stop codon. A phylogenetic tree reconstructed with the maximum likelihood method depicted a clone relationship with eight species of genus Coilia and our previous study based on the amino acid sequences of 13 mitochondrial PCGs. The complete mitochondrial genome is a valuable resource in classifying and conserving C. brachygnathus.

Sequence and phylogenetic analysis of the mitochondrial genome for the Northern Anchovy, Engraulis mordax (Engraulidae: Clupeiformes).

Project description:The northern anchovy, Engraulis mordax, is a small planktivorous fish from the northeastern Pacific Ocean that is an important forage for fishes, birds, and marine mammals, and is also the target of a commercial fishery. Here, we assembled a complete 16,664 bp genome for the E. mordax mitochondrion, which encodes for 12S and 16S rRNAs, 22 tRNAs, 13 protein-coding genes, and a 1016 bp D-loop in the characteristic arrangement of Order Clupeiformes. Phylogenetic analysis confirmed the evolutionary relatedness of E. mordax to other fishes of Family Engraulidae within Order Clupeiformes, but also indicated non-monophyly for the herring family, Clupeidae.

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.

Multiple freshwater invasions of the tapertail anchovy (Clupeiformes: Engraulidae) of the Yangtze River.

Project description:Freshwater fish evolved from anadromous ancestors can be found in almost all continents. The roles of paleogeographic events and nature selection in speciation process often are under focus of research. We studied genetic diversity of anadromous and resident tapertail anchovies (Coilia nasus species complex) in the Yangtze River Basin using 4,434 nuclear loci, and tested the history of freshwater invasion of C. nasus. We found that both C. brachygnathus and C. nasus were valid species, but the resident C. nasus taihuensis and the anadromous C. nasus were not different genetically based on Bayes factor species delimitation (BFD*). Maximum likelihood tree, Network, PCA and STRUCTURE analyses all corroborated the results of BFD*. Two independent freshwater invasion events of C. nasus were supported, with the first event occurring around 4.07 Ma and the second happened around 3.2 Ka. The time of the two freshwater invasions is consistent with different paleogeographic events. Estimation showed that gene flow was higher within ecotypes than between different ecotypes. F-DIST analyses identified 120 disruptive outliers by comparing C. brachygnathus to anadromous C. nasus, and 21 disruptive outliers by comparing resident C. nasus to anadromous C. nasus. Nine outliers were found to be common between the two comparisons, indicating that independent freshwater invasion of C. nasus might involve similar molecular pathways. The results of this study suggest that adaptation to landlocked freshwater environment of migratory fish can evolve multiple times independently, and morphology of landlocked ecotypes may cause confusion in their taxonomy.
