Complete mitochondrion genome of the endangered Mohave tui chub Siphateles bicolor mohavensis (Cypriniformes: Cyprinidae).

ABSTRACT: The Mohave tui chub (Siphateles bicolor mohavensis) is an endangered cyprinid fish endemic to the Mojave Desert region of southeastern California, USA. Here, we describe the complete 16,607 base pair (bp) mitochondrial genome of S. b. mohavensis. The mitogenome has a nucleotide base composition of A (29.08%), T (26.91%), G (17.58%), and C (26.43%), and encodes 13 protein subunits, 22 tRNAs, a 12S rRNA of 956 bp and 16S rRNA of 1691 bp, and a 929 bp D-loop control region, each located in the conserved mtDNA structure typical for cyprinid fishes. All protein-coding genes have initiation codons of ATG or GTG, and only the ND1, CO1, ATPase8, NDL4, ND4, ND5, and ND6 genes have complete stop codons. Phylogenetic analyses confirmed the relationship of S. b. mohavensis to several genera of cyprinids (e.g. Gila, Acrocheilus) also endemic to western North America. This characterized mitogenome may help inform management practices for S. b. mohavensis by facilitating future studies on how allopatric populations of this imperiled species are evolving across refuge habitats.

The complete mitochondrion genome of the Barbodes hexagonolepis (Cypriniformes, cyprinidae).

Project description:The Barbodes hexagonolepis, as an important commercial species, had the limited resources on biology and genetics. We reported the complete mitogenome of this species, and got a whole length of 16?587?bp (containing two rRNAs, 22 tRNAs, 13 mRNAs and one D-loop region). The two rRNAs located between tRNAphe and tRNAleu and were separated by tRNAval. The 22 tRNAs was ranged from 66?bp (tRNAcys) to 76?bp (tRNAleu and tRNAlys) in length. The 13 mRNAs had four overlap regions, three types of start codons and four types of termination codons. The D-loop region was found between tRNAPro and tRNAPhe. To further explore the phylogenetic relationship of the B. hexagonolepis, we constructed the phylogenetic tree and verified that the B. hexagonolepi was a part of the Barbinae and independent from other genus of the Barbinae. This result provided the valuable evidence on phylogenetic relationship of the B. hexagonolepi at the molecular level and essential resource for further research on this species.

The complete mitochondrial genome of Leuciscus merzbacheri (Cypriniformes: Cyprinidae)

Project description:Abstract Leuciscus merzbacheri (Zugmayer, 1912) is a cyprinid fish endemic to China, with a distribution range limited to Xinjiang Province. As a landmark species in the Junggar Basin, L. merzbacheri is of considerable significance regarding our understanding of the adaptive evolution of salt and alkali tolerance. In this study, the complete mitochondrial sequence of L. merzbacheri was obtained for the first time by high-throughput sequencing. The circular mitogenome is 16,609 bp in length and contains the standard 37 genes, including 13 protein-coding, 22 transfer RNA, and 2 ribosomal RNA genes, which is similar to that of other fish. The mitogenome contents of A, T, C, and G were 27.9, 26.3, 27.1, and 18.7%, respectively. Phylogenetically, L. merzbacheri was located on a new branch near the base of the phylogenetic tree, thereby suggesting an early origin.
